Welding Aluminized Exhaust Tubing. Piggy Bank Welding Project. In part 1 I tig weldedbrazed some threaded pipe couplings on some end caps.
A coating of pure aluminum on steel provides a very durable and cost effective corrosion protection. Otherwise the flames can burn the tubing. You can weld aluminized tubing with gas metal arc welding GMAW using ER70-S6 mild steel filler metal and 75 percent argon25 percent oxygen shielding gas but this will leave the finished weld zone unprotected because the aluminum will be burned away.

We would always sandblast the parts we were going to aluminize first with extra fine blasting media.

A user if want to bend down the pipe in the middle of welding it can be down with spot welding too. TIG welding is ideal and built for welding thin metal sheets such as exhaust tubing.
