Q. What materials are used to make brazing torches?

Answer

The brazing torches, unlike the process of soldering, need to sustain a very high temperature level. This is particularly required because filler materials need to be molten onto the joints for a copper to copper or brass to brass or brass-to-copper welding connection. The operating temperature of a brazing torch is as high as 2500 degree centigrade or Celsius. The joints produced by brazing are much stronger than the soldering or sweating technique. The brazing torches have a brazing rod, through which the flame is shot onto the brazing area. Brazing rods are typically made out of brass. When we are brazing common alloys, then the filler materials are used as either copper, nickel or even silver, whereas for specific purposes, one may also use aluminum and gold, although they are rarely used.
