What should be paid attention to when welding galvanized steel pipe
What should be paid attention to when welding galvanized steel pipe 1. The premise must be polished The galvanized layer of the weld must be polished away, otherwise air bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce the rigidity. 2. The welding c...Read more -
