Can You Weld Black Iron Pipe? (Is It Safe?) • WelditU

Welding black iron pipe. You can weld black “iron” pipe because it’s made of mild steel, not iron. Black steel pipe can be welded using any welding method used for steel. This includes MIG, flux core, TIG, and stick arc welding.. But black pipe fittings are made of malleable black iron. Black iron fittings are difficult to weld without causing damage to the fitting.
