I'm trying to put together a small structure using galvanized steel electrical conduit (3/4) and I can't seem to find a T-junction conduit coupler anywhere. I'm wondering if I could weld the tubing together, but I'm not sure if I can weld galvanized steel. Also, if I can weld them, is there any special technique that I need to use outside of regular acetelene/oxygen torch and solder?

Can You Weld Galvanized Steel
Conduit is made from low carbon steel. Then the galvanized coating is applied. The fumes from the coating are poisonous when heated. So your choices are to remove the coating then do your heating. They can be soldered, brazed and welded. It all depends how strong you want the joint and how high a temperature used. If you use silver solder the joint must be very tight. If you use lead solder a flux must be used same as brazing. Welding is the strongest and the melting temperature of steel is about 2600 degrees.
