I went to pick up an air conditioner drain pan for our building engineer. It was on my way home, I know the owner of the metal shop, and what better reason to go to a welding shop.I picked up the pan and it looks like it was soldered? I have the need to tack/weld SS and saw this and would like to know what it is.It was smooth, no welding marks. Looks like a lead solder type joint. There was a drop in the pan as well.Hope someone knows. I would not think Oxy as no discoloration. But I have not heated SS so maybe this is normal. Also, there was a SS to copper weld as well.Thanks for any input. Attached Images

I will be picking up an argon tank next week so I will find out.Figured I would ask here first.Soldered with gas, a soldering iron? And type of solder, to bond copper and stainless? Silver?
Reply:Thanks Rojo,I have all of the my garage here. Will have to try it. Bought it way back for copper, didn't know about stainless. Only problem is I only have Oxy/A tanks. Gave the propane and mapp away when I got them.I will have to try it with them. Thanks for the info.. I thought it was be tig, then went to pick it up and said what the heck.
Reply:If you use oxy/ acet, keep the heat low... you can overcook the material for solder, and nothing good comes of it. If I use a mix gas for solder, I just keep the torch further away from the workpiece.And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.
