Welding coated sheet metal
Welding coated sheet metal
(OP)
Is it possible to join, by welding, gauge steel sheet metal with a corrosion protection such as aluminium or galvanized and keeping the integrity of the corrosion protecting in the weld area? Where can I find out about the process and technology? This application will incorporate automated and manual welding.

One process I can think of is brazing-we fabricate guttering/spouting for Agricultural buildings and we've found that brazing with a low melting point filler rod
acheives great results and no corrosion(some of the gutters
have been in place now for 4 years and there is no reports
of corrosion).However this may not be practical in your
application.

And from my experience paint itself doesn't bond well to zinc.
I thing the label of cold galv. states close to a 90% zinc content. The only possible option is to hot dip the part.
