I’m reasonably sure, having experience welding, that my 1983 Gregor is stick welded. Just by bead shape and puddle fill. Don’t know if that’s good or bad, the little bit of repair welding I did on it I TIG welded. But it’s a pretty solid little boat. Pretty sure everything now is probably TIG or more likely spool gunned.
I have a buddy who used to build aluminum semi trailers, they were all TIG so maybe boats are too. The one guy I am friends with who does a little boat building does it with aluminum MIG.
