Well, gas welding gives you the opportunity to reheat the entire joint, allowing for "stress relief" of the joint. It's a lot easier to "touch up" a gas weld, since you can "push" the puddle around and fill in. I have found gas welding of thin tubing to be way easier than MIG. Interesting note: Stinson 108 series aircraft were stick welded. dale still stephen langford wrote: > FlyBaby > > Here's a question I have for someone- > Welding 4130 with a MIG or TIG as compaired to GAS welding, is it true > that electric arc wlding cools down too fast and makes a brittle joint > where gas heats the metal evenly with a slower cooling resulting in a > stronger weld? >
