Laser Brazing

Laser Brazing

Laser brazing is hard soldering with a laser beam. The process is used in the automobile industry, for example, for joining together galvanised vehicle components and body parts, among other things.

Laser brazing is hard soldering with a laser beam. The process is used in the automobile industry, for example, for joining galvanised vehicle components and body parts, among other things. The process is a relatively cold process where the base material is not melted and any zinc layers next to the join remain largely intact. In general, laser brazing joints have very smooth weld surfaces that normally do not require any further finishing.

How does it work?

The principle of laser brazing rests on melting a cold brazing wire using a laser beam. The brazing wire is introduced into the weld seam via a wire feeder unit and then melted by the laser beam. The wire material then flows into the weld seam and forms a brazing joint.

 

The most common brazing wires includes CuSi3 (copper-silicon) and CuAl8 (copper-aluminium). The process can only be applied automatically by attaching brazing optics to a robot.
