Brazing Copper Sheet

In brazing and welding fabricators add a filler metal into the joint.

Brazing copper sheet. The filler metal can be aluminum silicon brass bronze copper copper silver gold silver nickel alloy or silver. The equipment in this project can be bought for as little as 30 dollars. The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process while also requiring much.

Brazing is a quick and inexpensive alternative to welding. Brazing is also much easier then welding it s a lot like using a glue gun. However the major differences are the following. Use a torch that produces a high intensity flame.

In brazing the filler metal has a lower melting point than the adjoining metal. In actual practice for copper systems most soldering is done at temperatures from about 350 f to 600 f while most brazing is done at temperatures ranging from 1100 f to 1500 f. Brazing is similar to soldering but at higher temperatures. The choice between soldering or brazing generally depends on the operating conditions of the system and the requirements of the governing construction codes.

Brazed metal can also be stronger then welds. Brazing is a metal joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint the filler metal having a lower melting point than the adjoining metal. Use the right brazing rod material for the metal used in your project. Bradford sheet metal joining copper sheet metal and soldering.

Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces themselves. The phosphorus in these alloys acts as a fluxing agent on copper. Fluxing is an essential step in the brazing operation aside from a few exceptions.
