Can stainless steel pipe and galvanized pipe be welded?

It can be welded.

Thin-wall stainless steel pipe and thin-wall galvanized steel pipe welding, to use argon arc welding machine to welding, because zinc in oxidation, will produce white zinc oxide smoke, will cause welding spot virtual welding, so to use Angle grinder to polish smooth after welding several times, although troublesome, but more processing can be successful. If you use acetylene oxygen to oxidize the galvanized layer first, the effect will be better.

Both are thick-walled tubes. You can remove the galvanized layer on the surface of the galvanized pipe by machinery first, and then use argon arc welding. It is easy to weld successfully. However, before welding, the wall of the two kinds of pipes should be sloped with an Angle mill, so that the finished products can meet the requirements.
