Re: [PSUBS-MAILIST] welding sheet metal



Dean. How about welding them up, then turning them over and filling with water. If it drips, it's leaking.
Mig is nice and fast but prone to pin holes with thin material. You're bound to get a few, at best.
I think the brazing would plug up the holes, but the extra heat could cause other problems.
If the holes are just tiny pin holes, the epoxy will probably plug them well enough for open mbt's.
If the tanks are open on the bottom, do you have enough room to weld both sides ?
Won't get any leaks that way. I wouldn't worry much about a few tiny holes if you're sealing it all with primer and epoxy. Mig pin holes are usually so small you can barely see them anyway. Frank D.
