Introduction to Common Brazing Processes


Braze Fitting

Flame brazing: Flame brazing is a brazing method that uses a flame formed by combusting combustible gases, combustible solid or liquid fuel and oxygen or air to heat the workpiece and brazing material. The gas used for flame brazing can be acetylene, propane, petroleum gas, atomized gasoline and so on.

Resistance brazing: A brazing method that heats the weldment and melts the solder by using the resistance heat generated by the current passing through the weldment, brazing material, or the contact surface between the brazing material and the weldment.
Induction brazing: A brazing method that places the to-be-welded part of the weldment in an alternating magnetic field to cause an induction current in the alternating magnetic field to heat the weldment and melt the brazing material through the current thermal effect.
Brazing in the furnace: a method of heating the brazed parts with brazing materials in the furnace and brazing. There are four types of commonly used brazing furnaces, namely air furnace, neutral atmosphere furnace, active atmosphere furnace and vacuum furnace.
Immersion brazing: Welding parts are partially or entirely immersed in salt mixture or liquid solder, relying on the heat of these liquid media to heat the parts to the brazing temperature to achieve the brazing process. Dipping brazing is divided into salt bath brazing and immersion brazing in molten solder.
Arc brazing: Arc brazing is a method of brazing by transferring heat from the arc to the weldment and brazing material.
Carbon arc brazing: Carbon arc brazing is a brazing method that uses the arc generated between the carbon rod and the workpiece to heat the base material and melt the brazing material to achieve the connection of the base material.
