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.
