Laser applications: aluminium/steel sheets assembly by laser brazing along with tin.
The laser sources commonly used are fibered diode lasers.
So that we can do the brazing, we use a brazing head.
This head integrates the wire bringing system in it for the focusing of the laser beam.
The optic must be carefully chosen so that we can have a wide enough beam to cover the entire wire and also heats up the part to be brazed to ensure a good wettability.
