Today we're going to demonstrate how to butt weld sheet metal using a Lincoln Electric mig welder. Like anything, there's a right way and a wrong way to butt.

Butt welding sheet metal is a fundamental welding technique that involves joining two metal sheets end-to-end. This process creates a strong and durable weld, making it an essential skill for fabricators and welders across . Using a simple grinder to achieve a perfect butt weld.
Butt welding is a fusion welding technique used to join two pieces of metal along a single plane. It involves bringing the edges of the two workpieces together and then melting and fusing them to create a strong and continuous joint. If you’re replacing entire body panels, it is strongly suggested you stick with the factory seams and avoid creating new “butt joints,” where the ends of two pieces of sheetmetal are butted together and welded. Learn why MIG, pulsed MIG, TIG and pulsed TIG are the ideal choices when welding sheet metal. When welding thin metal, the main objective is to avoid warping, burn-through and excessive heat-affected zones while still .
Welding auto body sheet metal can present challenges for welders but Ron Covell is here to help mitigate warping with both MIG and TIG welding.The best way to weld sheet metal panels together is by butt-welding, which is joining them side-by-side (see picture below). Butt-welded panels withstand stress better than any other type of weld joint. Overlapping is the absolute wrong way to do it and butt welding is the only quality way to do it. if you overlap then you are wasting your time because you are doing nothing but inviting rust back into you panels for the future. Take the time to learn to butt weld an do it right or stop doing metal work. Theres no in between.

A good lap weld might be better than a bad butt weld. Do a few tests on some scrap. If you use lap welds make sure to seal the back side to keep out moisture. I did some years ago & sealed the back with penetrating epoxy from a boat shop. 20+ years & rust free. I have also butt "hammer welded" stuff with a torch. Very slow but good results. butt welding is the correct way to do it. you will be welding real metal so warping really shouldn't be an issue if you move around. do a couple practice pieces to get the settings right and find a comfort zone. it's only metal and any screw ups can be repaired if you don't warp the shit out of it. just take your time and you'll get the hang of it real quick. good helmut, good . Butt welding tight fit panels is the way to go, low heat, spaced out tack welds, a cold wet towel, or air blow gun to cool weld area quickly, Now I'll go in and hot seam weld 3/4 inch at a time, jumping back and forth from all the areas.
1 dont butt weld panels on the car until you know how to butt weld !!!!! 2 use the correct size tip with a neutral flame that is as big a flame as you can get from the tip NOT A BIG TIP WITH THE FLAME TURNED DOWN 3 spend some time welding strips of panel steel together learning WHAT HAPPENS TO STEEL WHEN HEATED IE IT EXPANDS then and only then . A weld with a gap will require more wire thus more heat producing more distortion We are not welding battle ships, just thin sheet metal. With zero gap you use less wire with less heat being used to make the weld. The weld is smaller and takes less time to grind, again less heat. The smaller the weld, the easier it is to metal finish.

It’s easier for me to tack in place with the Mig, then gas weld. I have a 3-1 machine that has Tig, I’m just not good enough to use it on light gauge metal. With a O/A I can come “in and out” and control things. My 3-1 doesn’t have a foot pedal so I . The thing about lap welding is that the metal cannot be shrunk and worked easily after welding, due to the different thicknesses you now have. Then, extra filler will need to be used. That is one of the reasons that butt welding is preferred, the other being that after working the metal, there is not a largely visible repaired area.---John I dont like flapper wheels on sheet metal they seem too soft and form over the weld (which if you are mig welding is harder than the sheet metal) and dig into the surronding area. Try an abrasive disc with a hard backer (like a 2 or 3 in roloc on angle die grinder or 4 inch abrasive wheel in 36 to 80 grit).
