I've already done most of the welding for the Hummelbird I'm building, so this is academic at this point, but the plans say to TIG or torch weld the 4130 parts, but then to stress relieve them (heat to cherry red and allow to cool) all the parts after welding.
If I'm stress relieving everything anyway, is there any reason I couldn't have used MIG instead of TIG?
