Video subtitles:
  • 00:00: look at the bathtub constantly analyze how liquid is it and how it flows arc welding part 2
  • 00:38: Hello my Name Is steve blyle and I'm a welder when you work in welding industry or home workshop welding always works it looks like you need connect two pieces metal so that they kept there is a lot opportunities combine different metal not only different thicknesses welding position or Strength requirements
  • 01:08: but also individual engineering skills each welding seam make individually so let's consider the main day independently stationary or portable welding apparatus he provides you and alternating current or disis dc to the electrode alternating current flows in both directions there is a break in only some welding Electrodes developed with stabilizers in coating to hold an arc despite the break welding machines for
  • 01:38: direct current provide strong the flux of electrons in one direction current direction is called polarity it is determined by how wires are connected to Welder, plus a electrode polarity is usually used for welding sheet conventional metal electrode used for welding of carbon became fast cooling and filling with characteristics suitable for different situations rapidly cooling have a strong arc helping to burn pollution on surface movement
  • 02:08: on a circle or side in help form welding seam and for thin slag layer can be brewed in steps for the maximum two wires for vertical seam 6010 and 6011 can be used for welding with feed up or down it good electrodes for potholders and lightly rusty metal also brewing of gaps or poorly fitted connections and for first pass for good cook filling electrodes penetrates
  • 02:38: not so deep they scrape the seam stabilizers in the 6013 coating makes it the easiest use of small layer heavy slag holds the bow to the tub 6013 can also used with feed up and down for vertical Welding for welding general purpose 6013 makes smoother finishing stitch 7018 contains in coating iron powder he also has depleted hydrogen thick slag covers the entire bathtub
  • 03:09: excluding seats directly Under the electrode, carry them directly from or movements from the side in the direction of the arc hold on the front edge of the bath vertical position 7018 cook on upwards 7018 requires a better management electrode but provides a very strong stitch for loaded situations and provides very smooth seam for welding of any metal welding electrodes available in any quantity would be good hold fast cooling and
  • 03:39: filling close electrodes good with gloves cap keep clean Filters in welding also always wear protective goggles before lighting bend the arch conveniently click to ignite the arc and transfer the electrode to the start and start Welding bath hold down constant arc gap and set the current sufficiently large for its formation molten metal follows heat check that about me are filled to not pinch put a point
  • 04:09: leaving a little additional metal and extinguish arc on the seam you need to check your seam for availability Defects you need see the seam when he this whole the cost of the process control the heat and filling metal during welding observing and understanding Welding bath see after electrode focusing on welding bath look at the edges and on formed seam constantly analyze how it is
  • 04:39: It flows and how much liquid and make corrections when it need installation long set current through the electrode is main regulator amount of heat for welding if the current is small then the bath has outline of the electrode with increasing current heat is generated sufficient for forming Welding bath when does it start provar and you control the edges bath and formation seam is not accurate rigs of the foot
  • 05:11: virtually every welder sees them differently also affects the thickness metal and position for welding will be be required different quantity heat look at bath look at parties and see on an electrode sometime increases in the bath permeates steps spread finally filling metal becomes liquid and boiling that you just can not more to manage experiment with current settings for good cook and smoother suture and
  • 05:41: set the current so greater can keep bath so she does not became too large and uncontrollable and for characteristics of plaster bath will behave differently depending on the type the whole electrode It is visible at using 6010 and 6011 slag covers the top edge of 6013 but melted metal is still visible on it should easy to manage electrode 7018 slag covers the entire bathtub
  • 06:11: but you can still see the flow of edges and slag cooling down from the electrode during Welding Filling metal freezes below the slag the ashlag remains melted in horizontal and vertical position slag can to drip you will not deceive thinking that the seam too hot for you perhaps to experiment current settings for 7018 Well you will get the best result with more hot installations no matter what or
  • 06:41: work you use current only provides heat tilt angle determines how fast metal will be warm up if electrode perpendicular welding bath is formed spreads quickly you can move faster to limit cooking to thin metal less metal for a small seam or flattened shock embedded if the electrode incline heat leaves metal allows you to do lower speed welding for forming a seam if tilt the electrode
  • 07:12: metal is too strong will not warm up the weld pool will be the piece I found will be choose and you lose control at the edges for majority fitted you can hold constant angle electrode to formed dense the seam, however, some situations you will need to change the angle of the electrode in welding time for filling the gap in connecting electrode can be tipped slowing down transfer of metal and keeping the size then raise
  • 07:43: electrons to end a shock for angle control electrode need practice but you need stay free relaxed when you cook horizontal seam entered the corner you need to hold constant width baths watch the bathroom if the speed is too great metal is not enough time to warm up therefore bath will be very Narrow if speed too little metal it will be heated by will expand depending on
  • 08:13: metal electrode can spread in different parties or roll off always manage the size of the bathroom welding speed the last is the gap arc this distance from electrode to metal welding machine for sheet metal are used energy source direct current when installed current-voltage changes for arc retention It is necessary to avoid sticking of the electrode into the metal or retention electrode too far away but you can
  • 08:43: use minor changes arc clearance for heat management and seam shape is difficult but the average length of the arc is used for seam formation short arc reduces heat cooling bath try a short arc on the vertical you will have 7018 thicker joint slight elongation arc will cause an increase heat and bath spreads is used for perpendicular position of the electrode and small joints or
  • 09:13: flattening of the seam on heavy metal is important hold right clearance changes in arc clearance changes the number of does not become warm difficult to keep flat bath if we consider all aspects of welding that is a lot opportunities cooks in different ways practice and experiment try to the bath did what you need see how to boil Other if you have opportunity you need
  • 09:43: see the bath at the end electrode and develop a style suitable for you we observed heating metal to let the bath boil down and melt overheating also acts on base metal metal consists of Roughly at home in uniform crystals when metal is heated to certain temperature if it cools down quickly formed small crystals they harden cold slower atoms to contact and
  • 10:13: form large crystals that do not know the metal is softer in welding time metal near the seam it becomes hot enough in order to change structure of crystals relatively small heated region it will cool faster and will give less crystals they will become solid will be located air and welding also calling connected pieces of metal tension hot metal expands into welding time metal superimposed in the most extensive when we have you are not he, we are
  • 10:44: if the metal can move it will be pull in the direction seam if chunks metal clamped molten metal will still be shrink causing residual stress in metal there are many ways avoid this for metal that free if it is possible to cook with both sides reduce care for pipes or squares use sequence seams to manage care large temperature difference gives a great effect on metal
  • 11:14: if it's too cold use the burner to heat the metal the condensate will appear Greeks until the moisture is not will also dry if you cook high carbon steel which is not too well tolerates tensile-compression preliminary heating can be is necessary to avoid the seam from cracks when it will be cool down low carbon steel fatigue on stretching and compression for large salt and load on the final product in most cases project is constructed in this way
  • 11:44: so that the load on the seam was not close to the maximum strength of the seam or metal start welding first should be avoided seams more than it is necessary when you finish the metal slowly cool down if metal will break near the seam you need review either thickness of metal or the whole project well let's we connect two pieces metal together welded joints
  • 12:19: the first step before any type of welding this is preparation metal and fit connections if you work with a new mostly must be processed factory scale dark cover on surfaces use grinder to clear metal from paint or rust pollution on surface causes discord lack of fusion or problem on the other when you metal cutting save edges direct
  • 12:49: rectangular if use the burner remove leftovers process of cutting during adjustment do good pothookers to keep elements not save constant preliminary gap uneven clearance in the compound for welding makes welding more difficult than it should we escape many problems with cleaning of metal spend time on fit there is a lot varieties welded joint in basically there are four type connection is butt in
  • 13:20: overlap pumpkins angular with butt joint should boil in depth and depth filled with metals and less thickness the metal for the maximum strength use one hundred percent pro wars fully melted by my edges when connecting lapped seam is called a tape he fits into height and width equal to the thickness metal and seam lightly semicircular ribbon seam also used for t connection when one
  • 13:50: element joins the surface of another welding on both sides reduces the required size seam providing strong corner connection connection happens edges or angle preparation of metal and fit provides sufficient cooking and the volume of what we will stop at butt joints it can be done on plates flat bars angular tubes and square tubes with thickness of metal up to three millimeters make the edges straight
  • 14:21: and square for good overall compliance get a good one penetration just by putting pieces especially if you cook from both parties or in a circle for sheets or bars do potholder by edges to help heat transfer of the ring for square pipes grab the corners grabbing opposite edges in order if you plan to tank for smooth you can leave a small constant gap when possible start on the outside
  • 14:51: do not lay the edge more metal on the seam flat hold the electrode nearly perpendicularly metal can brew 6010 and 6011 using circular motions slightly reduce the current and cook faster to provide cook but do not burn metal for more smooth seam on try 6013 or 2 and 3 millimeters 7018 using the motion from side to side for horizontal seam hold the electrode
  • 15:21: nearly perpendicular to the seam watch the bathroom for 6010 and 6011, change the the welding speed to the bath spread and did not overlap metal see upstairs to avoid undercuts 6013 and 7018 cook directly without electrode movements hold down constant arc gap and welding speed if you can establish connection 3 millimeter metal easier to cook vertical position down three millimeter
  • 15:51: metal is quite thin for the electrode, therefore practice on a separate piece of iron to understand what use current and what speed cook from three millimeter need splay for a good cook bevel is made under angle of 30 degrees upper edge of the straight line at the bottom is flat landing hold grinder for small angle using the bottom the end of the disk for removal of metal when almost ready use the entire disk not and alignment for
  • 16:23: thick metal easier to do with using the burner and polish it bulgarian argument for the bevel serves in the bathroom in connection depth if through the narrow you you can not get it electrode to the bottom then you can expand the sample cut the Bulgarian using the bend of the disk to expand goats bevel may be is divided into three parts the root is where the first
  • 16:53: the passage he fuses but the compound fill and cover There are a few opportunities adjust connections butt-end there is a difference like between root wires in parts with bevel can leave a small gap then in the first passage is possible deep brow for 100 processor is used the lining then first pass falls into three piece or leaving a gap between plates the root is glorified actually there is a seam on
  • 17:23: back side after the first pass other passages filling on the lid are the same and so let's look at how begins connection every time when you cook the bevel you need to hold the electrode nearly perpendicularly metal to the top the seams were flat if you tilt the electrode will appear crown leaving the slag which will interfere the next pass so that the seam is even it is necessary to cut grinders protrusions calling without so it's easier
  • 17:53: hold evenness grinder and try to fix it on the next seam also if the seam is all still began to speak inside the bevel use the Bulgarian to cut the top to avoid capture slag not all welding situations require one hundred percent penetration is depends on the type load bag but always have to do leaving the entrance ramp small gap 6010 6011 provide good provar and do the first the passage is not
  • 18:24: much easier in any position of the seam to use a whip or step reverse squeezing motion for a provender and pushing into the bath for fill in, see on both edges to avoid undercutting for buildup use modified circular motion always come back to the cutting edge baths on the bottom connections if you cope with the bathroom You can also use filling electrodes 6013 and 7018 hold the electrodes
  • 18:55: for sure perpendicularly use small movements from side to side and avoid when fastening of electrodes to the wall in dependence on the bevel and the gap is possible will have to follow metal for maintaining the constant clearance of the main metal arc becomes thicker and up to fill bevel and takes more heat when cooking look on the edge of the bath as she floats and fuses with edges of the bevel after first pass on smash the slag brush and we are ready for
  • 19:25: filling caps if you can get both the sides of metals to you better to boil The reverse side for stronger seam cut out a clean metal save the same depth and width a little tilting the electrode slow down speed weld and make a seam Slightly wider than grooves and flush with surface some welding situations require full wire for strength if welded pieces are not precisely fitted or
  • 19:55: of high-carbon steel tend cracks in the first pass used lining bevel together lined used for verification of the structure aim to melt and boil down we put it prepare the band bevels with a few a smaller angle of 22 s half degree and thin edge clean the factory raid lining is narrow the strip will be tied or give
  • 20:25: surface in pollution warm up attach Come a gap of 6 3 millimeters this type of connection usually brewed by at least three with half to twenty two millimeters and you need to get to our an electrode can even to make a tack with reverse side or with bevel if with bevel cut the bulgarian to of pure metal always keep in mind that melting the bevel must be kept top of seam relative flat to avoid
  • 20:55: capture was flat hold the electrode is almost perpendicularly slightly tilted to the seam keep the arc on the front edge of the bath with weak movements from side to side pay attention to arc clearance you must see the edges of the tub offered to the edges skew avoid protrusion of the seam when you are using 7018 inside the bevel stay ahead went and slag if molten slag
  • 21:27: fall in front of electrode it can or loosen the arc or limit metal penetration at the edges on vertical seam you will have problems fusion base metal the tab you need hold a seam flat without undercutting around the edges cut electrode perpendicularly metal or a little tilt the bath should follow from the plane went but needed avoid undercutting move fast so that there is not
  • 21:57: overheating of metal because of which the bath splash down on you may be needed slightly reduce 5 amp not reducing not too much happens problems in vertical seam when it is colder rather than when he hot remember the top only gives heat to muse welding speed angle electrode determine how hot there will be metal but also butt-jointing head is not necessary do too
  • 22:27: large seam electrode keep perpendicularly adjust the speed Welding to the bath diverged without overheating of metal most problems seamstresses received is from bad management electrode when end of electrode jumps change gap arc and flow is not a plan constant and focused find a way Strengthen yourself so that you could manage electrode also if angle is aimed at back seam molten metal will take warmth and
  • 22:58: will cause fallout baths horizontal usually not is used for welding test but falls into practical tilt situations electrode up and a bit on the seam use the bottom bevel edge as a stop helping to keep seam which will be help small movement of electrons look up and push the bath alcohol set current sufficient for high speed welding in order not to overheat metal that will make the bath is too liquid
  • 23:29: do not try to pull many metals horizon niche allow parts tie them together and hold down filling metal and sags last type of roots is v-shaped open connection of seats and look at the electrode 6010 deep in the gap there is a seam on back side metal preparation and adjustment are critical so spend it time to metal the bevel edges were ready must be direct rectangular take away all factory raid on
  • 23:59: back side times half and brush inside square or round tubes landing should be the same use files to cut off the protruding points with three in millimeters 6010 I using 1 and 6 millimeter with landing 16 millimeters in size clearance of landing maybe a little change if you understand that you want to use this is for every seam which you do outer part of metal 16 millimeters spacer master make a gap
  • 24:30: pothaking liter it directly pattern before finish and tack remove the spacer potholders do not cool The battle and clamp easy to clean space check the seam on the smoothness and finish seize connection on heavy elements after first with masonry use small or medium screwdriver for clearance was the same and for limbs you can remove it afterwards how the seam will be
  • 25:00: caught completely with canine square take the pipes opposite pipe ends opposite elephants check that there was the same gap straighten it if need then leave two more potholes aboriginal passages flat horizontal and vertical overhead position are done in the same way cut the edges to were thin keep electrode perpendicularly metal chirk spark right on surface and push the electrode into bath and start move filling metal
  • 25:30: will grow under thin edges potholes and then he will leak right through and then move so quickly how much you can fill out gap if not runs right through then you will see as metal grows behind the electrode back because most of ester will be on back where a seam is built on back side metal you will want put quite high current start from whom to whom are you believe in the flat position if you burned a hole better stop
  • 26:00: return electrode back seam start on the edge hole and continue boil when finish the seam cut out the edges of flowers so that they thin with both parties and fill in and some procedures welding requires upper root the seam usually you need a current of 5 amps is not less simple prepare the metal in the same way enter the same seam hold electrode perpendicular and cook so much quickly the clearance is filled in
  • 26:30: some welders love to do landing is more subtle movement step will dig the groove then and fills up hole and again always fills up hold the electrode deep within the seam other welders like leave more thick landing and a wide gap and again use motion step put the metal and verified that when melted on the bottom corner lack of traffic step this is an opportunity stop undercuts on back side dignity that you
  • 27:01: see as done root for 100 percentage of penetration root step up also works when the gap inhomogeneous or stain seam with reverse side will be higher surfaces fully fused with mini pro cooked bevel edges in unsuccessful places available inadequate cooking if the welding speed will be too low The seam will be selected from reverse side causing unnecessary right at the front side because of cluttering
  • 27:31: of the metal will choose and there are undercutting with both sides with cut out the speaker metal that was not capture of slag metal for grinding will be thin therefore it is necessary make another seam called hot passage that will take more metal and co the remaining slag 6010 try the pass steps in time The hot passage is not going deep into reverse motion use fast feed therefore you can warm up and look around so that there is not
  • 28:01: You can also crop make hot three-pass half a millimeter 7018 hold the electrode nearly perpendicularly let's warmly Edge moving transversely relative to quickly see how grow show check that the edges in the bathroom liquid and seam top remains flat when one connection melted by one of the listed procedures you can fill a pore rupture here you get best result using 6013 and 7018 if metal is not thick you
  • 28:31: can finish one passage for heavy metal more filler, remove all the slag between passages of young and metal brush it comes with experience but simple welding with several passes required overlap with previous passages where only this is possible last filling passage should be slightly below the surface try leave leading edge miter with a weak movement me side to side pay attention to arc clearance
  • 29:01: so that the electrode does not grabbed by sides do not ask obliquely hold the electrode nearly perpendicular and try to avoid so that the seam protrudes to you may need accelerate and slow down to to govern number of transferable filling metal try to leave upper bevel angle on the final do not incline electrode to form protruding seam between use the edge bevel as guide helping to make a suture direct course seam should be the thickness metal, get out
  • 29:31: deep the cap should be slightly wider than the bevel level with metal surface filling with large what does it give me strength only the lines will be stronger heat metal if top too wide for hats one pass is necessary make several passages side to side to conclude with little movement side to side using bevel as a guide to the seam was straight use interior
  • 30:01: bevel as guide for second campaign at the end and speed welding and movements electrode to move into the air the first seam in the last pass in mostly bright keep liters more perpendicularly metal move straight and faster for a smaller metal transfer horizontal tilt electrode up use the mean length and move straight without movement electrode the first pass will be support the second
  • 30:32: pass so hold electrode perpendicular and move fast enough to withstand the shock for the final pass try tilt a little electrode of move fast for less than your vertically possible seam side to side or stitch small seams very lecture use edge of the seam to the first the passage was flat if there are a lot of stitches try it use another way how to guide to The seam was straight if
  • 31:02: you do not like multipass a structure use bastard's seam start with one hand let the bath closes the edges of the bevel cross the stage relatively fast here wait when bath will appear and will flow to the edge raise a little electrode cross Wait rise and cross all promotion will slow it will be more strongly heat a metal so a bit reduce current
  • 31:32: use the edges bevel as guides to retain seam edges straight outline seam at the edges and hold down constant arc gap and continue bind the weight we make it possible weld more metal but it is required practice stably flatten when you fill out or close you need experiment with current angle of the electrode and welding speed Learn to manage number of of the transferred metal and understand how much
  • 32:02: metal you can transfer without subsidence or splashing out compound a plus when butting together we connect the edges metal when one a piece covers another this connection lapped edge and especially the upper corner will be hot and melt faster than surface and will expand to the surface you want to melt the bottom angle and fill it up
  • 32:32: up semicircular welding seam compound overlaps can be done quickly cooling down electrode but filling electrode will give a smoother flat seam welding is called horizontal ribbon need to discuss two angles one relatively metal and 2 carrier own seam concerning metal angle of electrode determines the position tapes in the mix angle relative to the seam the angle controls the shape
  • 33:02: seam holding electrode perpendicularly heat quickly Heats the metal expand the bath for flat seam if tilt the electrode back the seam will begin protrude there are many variables look at the bath for 6010 and 6011 hold the electrode is almost perpendicular to the seam with an arc in the front the edge of the tub should be on the bottom edge push you wear then lead the electrode leading edge may be needed
  • 33:32: accelerate or slow down to divide heat translate the arc to front edge to melt the angle see how the bathtub floats on the top edge and become attached at the bottom quickly cooling liquors gives an excellent provar and is inclined to do flat or concave seam even on thin metal can be done second pass for ribbon seam filling Electrodes give more smooth seam hold down
  • 34:02: constant arc gap for smooth seam pick up speed Welding and angle electrode to the bath always flowed the top edge from behind that filling metal longer remains liquid cook directly without electronics hold the arc on the front edge of the bath on thick metal you may not it turns out ribbon seam for one pass then you can do for 2 upper ones is less and bad and move more metal and round out the seam second pass
  • 34:32: may be needed even three passage on the heavy seam use 7018 so that the bottom seam is not cracked put 1 seasoning the bottom end the slag and clean the seam a metal brush determine how far there must be a seam hold the electrode exactly up a bit on the seam and cook retaining the external straight edge electrode on compound perpendicular to the seam second seam fill up to
  • 35:02: of the upper edge ceiling ribbon the seam is similar to flat only more inconvenient guide the electrode in the corner pick it up with allowance for thickness metal hold the electrode is almost perpendicular to the seam and look at the bathtub near the edge superimposed piece as soon as you can keep filling base metal from overheating of metal remains in place on vertical external position the edge will be
  • 35:32: warm up stronger than surface cook from top to bottom a little tilting the electrode up transferring heat to back piece move in a corner and push the bathtub edge and back outside here take the speed welding hold in front van and check that you on the leading edge bath in the corner There will be no stitch growth when Welding vertically down so it's possible need a second pass vertical seam in welding up 7018 provides more
  • 36:03: strong seam also you You can give more filling metal in one pass always remember that 7018 very sensitive to The clearance of the arc is not cling it to the edges not lengthen the arc across the bevel transfer heat to back parts like only the bath will flow go to the corner allow filling metal blossom out you can even pull the electrode back if necessary to hold even arc clearance back in google a little across slowed down to
  • 36:33: the bath broke out hold the flow positions up and add current to not had to wait until the edges contact if something is not is obtained when welding up 7018 start with electrode diameter 32 millimeters smaller bathroom more easy to manage you also you can first take a step Passes down 6010 and 6011 6010 6011 down 7018 up he provides good cook and fill angles and lighter
  • 37:03: hold constant gap than cooking up for heavy metal need a bigger seam you can the headquarters of Lebanon welding seams sides to the use crotch overlapping joints easy to cook in any external position angle will melt especially on thin metal if the top edge uneven align its grinding remove the edge of the machine to align it t-shaped connections filling electrode
  • 37:35: is also used in accession it very similar to lap welding there is no outside edge which quickly heats up on t upper connection part of the seam will be demand more heat therefore tilt the electrode in the angle that you raise bath up if the angle not enough to allow welding bath swim up remain pruned 6010 6011 always take out arc on the cutting edge to fuse edges tilt the electrode to take a bath
  • 38:05: look up upstairs to avoid undercuts filling electrodes 6013 and of course 7018 provide more transfer of metal into flat position hold the electrode nearly perpendicular to the seam check that the bathtub flowing from above and from below try hold constant arc gap and welding speed if you need more seam size try use electrode of large diameter and or suturing
  • 38:35: ceiling similar to plasma hold the electrode perpendicular to the seam and push the tub up support constant arc gap and the welding speed is not I allow false metal overheat for more seams build them from above down vertical you reverse connections easier to cook down use modified circular movement is always moving in the front edge of the bath and push the bath hand
  • 39:05: put the current sufficiently large so that the bath expanded and move fast enough to stay ahead of molten look at the both edges avoid undercutting by edges 7018 up allow to cook faster first pass deep and tilt electrode a little up and attention to the gap arc when going into or metal then angle on the sides and this is insignificant move a bit in
  • 39:35: angle and forward grabbing electrodes on the side will cool the seam and suture removal will give more heat The main problem with welding up and hold correct amount of heat if the arc gap changes The amount of heat is changing too then it becomes difficult manage it keep metal from fall try retain the arc gap to only a bath flowed aside corner further to another
  • 40:05: aside when the bath began to flow move backwards set current for the welding speed to you did not have to long wait at the edges when you will gain experience physical management electrode can try out carry over metals while you are studying cook first necessary go deep but to support it avoid the same undercuts if you need more seam control clearance of the arc to second pass is much easier in depending on
  • 40:36: current settings suspend look at the edges that the bath floated move across faster and then linger and when the baths flows to the other end with just from the side in the party continues move up for heavy metal need a bigger seam you can increase the seams paradise or use a seam whip two connections in any position pulled into suture direction if you can achieve in both sides always Cook one side then another until
  • 41:06: the seam will end gusset the last corner connection in depending on welding position and how do you want finish the corner is choice of training to provide penetration on one part you can to make a bevel under angle of 45 degrees do it enough open to reach the electrode before bottom edge of the bevel will be heat up faster than the plane tilt the electrode
  • 41:36: found to tie both parts first passage 6010 6011 gives good food and they easier to manage on bottom of the seam 7018 try 32 millimeter electrodes for the first pass especially on horizontal and vertical position to do and top of seam to avoid slag capture use of edge as guides two covers on thin metal you can
  • 42:06: grab parts without bevel and then use Bulgarian cut the seam for some projects you can choose the angles with square edges angle can also be fitted with internal edges for the maximum take a steak with a small gap it is a plaster or not requires less cooking metal and for some projects can polish edges weld or make a chamfer through the angle in horizontal position direct the electrode in
  • 42:36: angle it almost perpendicular to the seam and hold down constant arc gap when both parts have one thickness very difficult heat exactly and pretty fast 7018 pick up the speed Welding to the bath heat near the top and lower edges move fast enough so that the metal does not sagged because of that that both edges quickly warm up filling metal will be more liquid leave enough metal but so that he does not
  • 43:06: sagged you have to do two passage to fill connection make the first pass so that he melted corner and bottom edge use the second pass to fill the top for thick metal plan welding Little with corners between series passages vertical position down more flat seam and maybe require more one pass at vertical upward 7018 outer edges will be will melt
  • 43:36: try an electrode smaller diameter for better manageability pay attention to arc clearance along basic metal and in angle along edge continue move a little fluctuate on external edges for any type angular joint do it so that the thickness of the seam was equal to the thickness of the metal if there are questions to strength of the seam you can put ribbon seam on inside it will pull together details inside when
  • 44:06: it is always possible do first external whisper I think you have ideas how can I connect two metal the details are together and there are many different opportunities for preparation and adjustment to provide cooking methods change care metals and reduce quantity of the transferred metal regardless of type connections over which you work for you need experiment current angle of the electrode and welding speed learn to manage number of transfers
  • 44:36: metal and understand how much metal are you you can transfer to how he will ask or drop out when you need to adjust the welding speed to manage the bathroom and use the angle electrode to control the shape of the seam focus on welding bath look at the binding edges and overheat metal besides spend Learn your time question and work safely on
