Induction Brazing


Brazing is a metal-joining process in which two or more metal parts are joined together by melting a filler metal into the joint. The metal filler  having a lower melting point than the joining parts is melt by induction and flows into the gap between close-fitting parts by capillary action and braze the two parts together. When the metal filler is brought above its melting temperature it is protected by flowing agent known as flux


Induction brazing is used to join a very wide range of materials, usually metals but also ferrous non-ferrous (alloys). As for the other induction processes also induction brazing is extremely precise and localized. The heat is brought to the joint area and the fillet only, without effecting adjacent areas of the brazed parts. Brazing joints are extremely strong, resistant against corrosion and guarantee perfect sealing. The brazed joint is clean and smooth and do not require additional machining processes.

Application fields

Induction brazing systems are used for a very wide range of industrial products. One of the sectors in which TESI brazing systems are more famous is the power generation industry. Our systems are used to braze transformer parts such as copper bars and rings or generator’s wirings, fan blades, compressor blades, gas and steam turbine blades, high pressure valves, fuel and exhausts pipes.

Brazing equipment 

TESI induction brazing systems is composed by static or mobile SHG power source generator and a dedicated coil. We offer a wide range of solutions, from the basic portable system to be transported on customer site to turn-key automized line with coils and quench integrated on anthropomorphic robots.
