Can you braze steel to stainless steel?

Answer 1

Yes, stainless steel can be silver brazed or welded with either an arc welder or a TIG welder. See link below, Welding Stainless Steels:

Answer 2

Aluminum and stainless steels cannot be welded together in the typical welding process. They have very different melting temperatures and they do not mix to form an alloy. They may be bonded together other ways, like soldering and a bonding substrate. They can also be joined together with fasteners like rivets or screws. One problem with bonding these two metals together is that they create a battery when an electrolyte is is present. This makes the metals corrode at a faster than normal rate.

Answer 3

Yes it can but special procedures need to be followed. Namely preheating the piece, and post heating for a few hours. If this is not possible then you can use an austenitic rod as a filler such as 309.

Answer 4

You can TIG weld using a 309L wire. This is a reasonably common way for joining stainless to carbon steel pipe.Stainless steel welding electrode type 309 and 310, used for elevated temperature applications, and type 316 or better type 316L used for enhanced corrosion resistance, are generally not prone to sensitization and are used with filler wires of similar composition.

Answer 5

no

Actually, despite the opinion of the previous poster, yes you can! Use a flux suitable for stainless and there should be no problems. I've done it many many times completely without issue.

Answer 6

Yes although the method for each are quite distinct.

Aluminium is extremely flammable if you get it hot enough. For this reason you have to surround it in an atmosphere of Argon when wielding.
