make sure to tack the seam together in a bunch of different places before starting to weld for any length of time. then weld a bit here and a bit there and let the weld cool before you carry on. if you don't the weld seam will look like a dog's hind leg. it will warp all over the place. if you don't do a bunch of quick tacks first to get the seam stuck from one end to the other the 2 pieces will start to warp and separate from each other. if planning an overlapping seam then you could use sheet metal screws to hold things together the whole length, then weld and remove screws as you go. only weld an inch or so at a time and make sure to let it cool so it is the same as the rest of the panel before doing another weld. have another project on the go to keep you busy and not be tempted.
