Steel can be soldered, but it's not real common, need to use acid flux.

Yup - when tin work was popular it was very common for it to be soldered. I know tin isn’t exactly steel, but it has similar properties. I’ve soldered galvanized sheet metal, but I can’t remember what for. Used a torch, lost of plumbing flux and heavy solder.

Yep and the answer to that one is in the composition of the galvanizing material. :wink:

Actually what I should have said is will a resistancce rig generate enough heat to "silver solder" I was really tired after work yesterday (night shift) and with the combination of some spiced rum and the late hour it just didn't come out the right way. I don't think my rig would do it but with some of the stronger rigs I wonder if it would work. Just wondering though as with the cost of those things ( I lost intrest talking to the sales rep after he sail "starting cost 1300 ) but then you need........

Rob,

Devil is in the details, eh? What you’re thinking of is spot welding, here are a few “choices”
