I have beer at my house, and thus I pose some questions If you will Monsieur Willard....
we have a few stainless bits and pieces around the car...some of the cooling system, some of the vac-u-pan lines, and also some heat shields and covers None of it is structural or very high pressure. Like the hack that I am I just weld them up with mild wire in the mig but there is something I have noticed .
The welds don't rust.
I would have thought the welds on the cooling system pipes would be the first thing ....
what gives?
btw: I make an effort to keep the welds as cool as possible, I tend to weld like I'm butt welding thin plate,bang, bang, bang......very short pulses.
