The fundamentals of low-temperature silver brazing - Part 5: Induction and resistance heating

Experience shows that flame–brazing is the preferred heating method for about 80% of all production brazing operations (see Part 4). There are two other popular heating processes, and these are induction and resistance. It is reasonable to describe these as the ‘electrical’ heating methods, and they are use to produce three quarters of the remaining 20%. Both of these heating methods are characterised by the benefit of closely localised heating of the joint area. Both will produce excellent results providing their use is restricted to those cases where their technical characteristics can be used to maximum effect. Despite the relative efficiency of both processes, their fields of application are not as universal as those enjoyed by flame heating.
