You can weld aluminized tubing with gas metal arc welding (GMAW) using ER70-S6 mild steel filler metal and 75 percent argon/25 percent oxygen shielding gas, but this will leave the finished weld zone unprotected because the aluminum will be burned away.

Can you weld aluminum to aluminized steel?

Aluminized steel is a metal that's most commonly gone through a hot-dip process with an aluminum-silicon alloy. There are other ways of doing it too, like galvanic coating, but the hot-dipping method is the most common. This is not a practical way of welding large pieces of steel to large pieces of aluminum.

Can Aluminium be easily welded?

You can weld aluminum to most other metals relatively easily via adhesive bonding or mechanical fastening. However, in order to weld aluminum to steel, special techniques are required. ... To avoid this, you must isolate the other metal from the molten aluminum during the arc welding process.
