Welding galvanized metal is a fast way to experience metal fever. It is not a joke. I first experienced it welding on conduit in an overhead crane cab. After that experience, I always ground the area to be welded.Grinding off the galvanisation would have made a stronger and easier area to weld.Start in the bend move quickly to the end of the thin metal. If youre not fast enough clean slag after every tack. If youre fast enough the slag will stay floating to the top. Now if youre not sure it will hold atleast you have more material on the steel that you can go over with a better more solid pass. Otherwise good for this thickness of steel using stick.
