Brazing Copper To Stainless

Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal.

Brazing copper to stainless. Tune in for today s tips on torch brazing stainless steel. Here are basic tips for silver brazing copper to steel or stainless steel. Once you do you will need to wash off your joint with cold water and do it again. Not using a pure atmosphere.

Induction brazing test with ubraze was able to braze the parts in 9 to 11 seconds for the full braze cycle. And don t burn the stainless. Otherwise the chromium in the metal at least 10 5 chromium by mass will oxidize and make the surface of the assembly appear drossy. Slip parts together and start heating the copper in a circular motion making sure to heat.

This week i want to thank you for helping me out and share what you taught me about. The copper pipes will pass steam raising from a container of boiling water. Heating treating stainless steel requires a pure furnace atmosphere. Clean the surface with steel wool or an emory cloth.

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. 9 to 11 seconds. These alloys contain phosphorus and are self fluxing on copper. These oxides inhibit the flow of brazing alloy and must be physically removed after the heat treating process.

Can copper stainless be welded brazed soldered. The steam will not have any pressure as the opposite end will be open to the air. Apply flux to both surfaces to be brazed make sure you have a flux that is capable of etching stainless steel. Copper to stainless steel.

However a key advantage is that many dissimilar metals can be joined to stainless steels by brazing. The copper pipe where it penetrates each side of the stainless box must be water tight as the box will be filled with water. 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. The brazing process can yield strong joints that are ductile clean and smooth.

1400ºf to 1600ºf 760ºc to 871ºc time. When brazing brass or bronze fittings stay silv white flux is required with these alloys. Once the solder melts onto the copper move some heat onto the ss. You guys helped me out with a bunch of kick ass brazing tips and tricks.
