Recommended equipment for flame brazing Since the principles of flame brazing can be explained using the most basic equipment, only the equipment necessary for manual flame brazing is described. From the basic principles, all other equipment is only a matter of the degree of automation the end user wishes to achieve. Hardware Torch It is […]
Flame brazing of aluminum is not new. In fact the very first brazed aluminum assemblies were produced using a chloride based flux and a flame as the heat source. What has changed over the years is the sophistication of the types of fluxes available and to a certain extent the alloy selection. Introduction However, even […]
