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 field in the braze joint components which in turn generated eddy currents in the work piece. Because of the skin–effect these currents and their resulting heat are created mainly on the surface of the assembly components. The distance of the inductor must be chosen in a way that the working temperature is generated almost simultaneously in the full joint area. For different contact shapes the geometry of the induction coil can be optimized to obtain short working cycles. One of the advantages of this method is the short heating time which limits the softening of the material components to be joined. Typical bond qualities of > 80% can be reached with this method also for larger contact assemblies. The widely varying working times needed for the different brazing methods are given in <xr id="tab:Brazing Times for Different Brazing Methods"/> <!--(Table 3.1)-->.
