what can i say tig is great, but you have to go really slow & the chance of warping is even greater. tig welding & equipment is not something for the average hobbyist. i have both tig & mig set ups at home & most of the time i go for the mig machine. i'm shaky handed & never should have been a welder in the first place but a welding fab shop is where this dumb redneck high school dropout ended up so that's what i became. holding the rod in 1 hand & the tig torch in the other has always been difficult for me, but i did learn to run a passable looking bead with wire. very nice looking & strong results can be had with mig. it requires proper joint preparation-meaning CLEAN- consistent technique & removoval of splatter. a nice consistent mig weld can look just as good as tig. i'm building a 39 chevy bobber truck. the frame under the cab & bed will be built with 2x3 & 2 x4 rectangular tube. i'm using the original front springs & axle so i'll need the rails in the front to have a curve or "hump". i'll do that by using 4 seperate pieces of plate to make my own tube in the desired shape. a corner to corner joint will provide 100% penetration & a nice chamfered edge just like a tube. if i can get back into practice ( fortunately i don't make my living that way anymore ) before i weld it i'll be able to do it without any grinding afterwards, it'll look that good.
