Each welding process requires specific precautions and equipment setup for a successful sheet metal weld. So, let’s discuss the preparation needed for each arc welding process before proceeding to the common problems with thin gauge welds. MIG Welding (GMAW) MIG welding works fine for thin materials .
Certainly works but I reserve it for places where every other method won't. I use 9 inch grinder, 7 inch sander, 5.25 inch grinder, 4.5 inch grinder, 3 inch cut off saw, 2 inch grinder, 2 and 3 inch sander (the 3 inch with sanding pads flap discs roloc discs etc) die grinder with carbide bits, wire brushes, stones and sanding drums, a Dremel with the full set of bits and pieces and . I need to weld some 22 Gauge sheet metal with my Lincoln Easy Mig 180. Question is, does smaller wire burn hotter because there is less material going in to cool the puddle?

Like any welding technique, butt welding sheet metal comes with its own set of advantages and disadvantages. . and MIG (metal inert gas) welding machines are commonly used for butt . Like asdf said, hopefully there's a slope setting you can tweak. . Well, looking at just the one picture, the weld does not look that bad. It is a bit fuzzy, or it might be my old eyes. . The joint will not lay in position long enough to tack. It's up to you to manipulate sheet metal to perfect position, then tack, often an inch at a time . I am a novice weldor restoring my 1953 MG YB. I'm finding that whenever I attempt to weld new metal to the old I am blowing holes in the old metal. I am scrupulously cutting out rust and grinding the surface clean. Both the old and new metal is 1.2mm thick, I . I have tried several different types of material with the same results, the welds look fine when laid down. I have adjusted the flow of gas from about 5 to 20 CFH. I have had a bad bottle of gas before and we all know what the welds look like with the wrong or bad gas.
To tack everything, the welder was set to voltage: 2, WFS: 30 with 75/25 argon/co2 and ER70S6 wire. I'm completely new to welding, so I'm still not sure what a good lap weld on sheet metal should look like. That being said, the tacks seem to be balling up very slightly.
