Can I solder galvanized steel to stainless steel?
YES You can weld or braze galvanized but first the zinc needs to be removed or it won't stick well with either method and welding on galvanized metals releases nasty vapors that if breathed affect the liver. I usually grind the zinc back about an inch weld and then use a cold process galvanizing spray to re coat, it works fine, I am in the process of building my grand kids a swing using galvanized pipe/ conduit and have made lots of things using this method.
