New Welding Thread ?'s for beginners...MIG

[parsonsj]

Josh,



Yes ... that's how I do it.

One other thing to keep in mind about warpage: it is caused by heat from welding, but is also caused by the metal getting pulled in place. If you have a gap between the pieces of metal when you start welding, the molten puddle between them will shrink as it solidifies. That stress causes warping. That's why you want to get even spaced tacks all the way around and progressively close it so that the metal pieces don't move (as much) from the solidifying puddle.
