Gas Torch Braze Welding

Gas torch braze welding is a joining process that uses a filler metal to join two workpieces.  Heat generated by a gas flame melts the filler metal.  Metal is then distributed throughout the joint by a depositing action.

Process Characteristics

Uses flame from a gas torch to heat the workpiece and melt the filler metal
Typically involves workpieces of steel and cast iron
Uses a filler metal, generally of a copper alloy in the shape of a rod or wire
Distributes the filler metal by deposition
Generally requires the use of a flux
