When welding 304 stainless steel ER308 ER308L and ER308LSI wires are compatible but for welding 316L stainless you need a 316L wire. This is because the strength of the joints depends on the number and size of the weld. Thus spot welding diameters go from 3mm to 125mm.

We need to establish what is considered thin metal. Its primary usage is in welding auto body and sheet metal. To weld sheet metal with solid wires use electrode positive EP or reverse polarity.

When starting to learn auto body sheet metal welding with a MIG welder you should opt for a shielding gas that has a higher proportion of argon gas. Ad Find China Manufacturers Of Sheet Metal Fabrications. Hot thread with new posts.

With these materials use a tri-mix gas 90 helium 8 argon and 2 CO 2.
