What types of solder are available for stainless? I know of the silver solder. But on a service call today, the homeowner/business owner was welding stainless. I asked him what type of solder he uses, and he said just plain old stainless. The welds looked great, but I have never seen "plain old stainless" on this site. Just wondering.

Welding & soldering are two very different things

My bad. I meant welding. Or whatever the substance they use to attach the 2 metals. I guess I just showed my level of knowledge on the subject!:lol:

So when you weld stainless what types of the metal rod or wire do they use? Is that "plain old stainless"?

Wondering if the guy is using standard mild steel mig wire or mild steel filler rod for a tig...works just the same only the joint will rust with the mild steel.

At 60 bucks a pound for SS rods you can't just call them stainless.One kind if for joining SS and ferrous steel and the others are for SS to SS.They also make food grade rods. LOL

Go by a tig and throw the rods out. Maybe have a couple for filler rod but if your joints are tight you tig without them. It is the only way to weld Stainless Steel in my opinion.

"Ditto" I agree 100%

Ditto.... however, since you may wish to solder, here's what you may find to be a useful resource/link: http://www.homebrewtalk.com/f51/soldering-stainless-steel-155782/

I hope that posting this link this isn't against any rules.

i have a question, I have seen flues made with copper & soldered on here, copper tubes soldered to the SS ( a sink I believe)

Why does the solder not melt & run when it is heated by the fire?

The liquid inside limits the temperature to close to the boiling point, well below the melting point of the solder. If you ever let a pan go dry you will quickly see the difference!

The classic example of this from boy scout camp is to boil water in a paper cup.

Thank you Riley
