Brazing is one of the popular joining technique for metals. Brazing is characterized by melting of a filler metal, its distribution on the faying surfaces of the parts to be joined, and its solidification.
The working temperature in brazing is below the melting point of base metal. Hence, only the filler metal melts. The filler metal has a melting point below the melting point of base metals and above 450 °C.
A properly done brazed joint exhibits higher strength than the filler metal due to the metallurgical bonding between the filler metal and the base metal. It is, however, weaker than a weld joint.
Due to the ease of use, faster cycle times, joining of dissimilar metals, and lower power requirements, it is used as an alternative to welding in various applications. It is extremely common in the repair and maintenance sector of industries. Aside from that, it is part of the manufacturing of automotive, electrical equipment, and jewelry.
