Brazing Copper To Stainless

However a key advantage is that many dissimilar metals can be joined to stainless steels by brazing.

Brazing copper to stainless.

Induction brazing test with ubraze was able to braze the parts in 9 to 11 seconds for the full braze cycle. Here are basic tips for silver brazing copper to steel or stainless steel. Once the solder melts onto the copper move some heat onto the ss. The steam will not have any pressure as the opposite end will be open to the air.

Ssf 6 silver solder and a propane torch are used to demonstrate how to join a piece of copper tubing to a piece of stainless steel tubing. And don t burn the stainless. Copper to stainless steel. Tune in for today s tips on torch brazing stainless steel.

Slip parts together and start heating the copper in a circular motion making sure to heat. Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal. When brazing iron steel or other ferrous metals select one of the stay silv brazing alloys such as safety silv 45 or safety silv 56 with safety silv white brazing flux. Once you do you will need to wash off your joint with cold water and do it again.

Do not use phosphorus bearing alloys as the joint may be brittle. When brazing brass or bronze fittings stay silv white flux is required with these alloys. This week i want to thank you for helping me out and share what you taught me about. These alloys contain phosphorus and are self fluxing on copper.

Can copper stainless be welded brazed soldered. Not using a pure atmosphere. 45 silver solder or better with white or brown flux to start but always point your flame at the copper allowing the ss to only get near the flame. You guys helped me out with a bunch of kick ass brazing tips and tricks.

Apply flux to both surfaces to be brazed make sure you have a flux that is capable of etching stainless steel. 9 to 11 seconds. Otherwise the chromium in the metal at least 10 5 chromium by mass will oxidize and make the surface of the assembly appear drossy. Clean the surface with steel wool or an emory cloth.

The copper pipe where it penetrates each side of the stainless box must be water tight as the box will be filled with water. These oxides inhibit the flow of brazing alloy and must be physically removed after the heat treating process. Heating treating stainless steel requires a pure furnace atmosphere. The copper pipes will pass steam raising from a container of boiling water.
