Brazing Copper To Steel Pipe

The brazing temperatures for most of the brazing alloys used to joint copper piping systems bcup and bag alloys see below are roughly between 1 150 f 621 c and 1 550 f 843 c.

Brazing copper to steel pipe.

Thank for you. If you re using silver solder that is solder with 45 percent silver or higher to connect copper to steel you must always use an acid based flux. When brazing brass or bronze fittings stay silv white flux is required with these alloys. But you can attach copper to steel with silver solder using a propane torch and call it whatever you like.

Unlike welding were we melt the two metals together brazing or soldering use a filler material to bond the two parts together without melting them. Step by step tutorial on how to braze copper pipe like a pro. We will be brazing or silver soldering refrigerant a c lines for hvac equipment. If you re brazing with a copper phosphorous brazing rod including those with silver flux is not 100 percent mandatory when working with lines that are also copper though it s recommended.

Clean and flux the area to be silver brazed use a tip that produces a flame that is hot enough to heat the area without taking all day but not so hot that it is hard to control. The most commonly used brazing filler metal types used to join copper tube and fittings fall into two distinct categories. These alloys contain phosphorus and are self fluxing on copper. 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.
