Brazing is a thermal process for the metallurgical bonding of metallic materials in

which a third metal component (brazing alloy or solder) is added. In addition a

described in Chapter 3.4.

The simplest way to produce braze joints is the use of a gas torch fueled by a

burning gas and air or oxygen containing gas mixes. For higher production

contact tip.

Furnace brazing is usually defined as brazing in a protective atmosphere or in

vacuum. Both processes do not require the use of fluxes.

surface layer changes the contact properties of these materials.

In this process the resistive heating under electric currents is the source of

thermal energy. For contact applications two methods are used for resistance

During induction brazing the heat energy is produced by an induction coil fed by

a medium or high frequency generator. This creates an electromagnetic alternating
