Two scanner mirrors deflect the laser spot and guide it along the welding contour at a very high speed. The joining surface is traversed several times per second, whereby the laser beam effectively heats and plasticizes the entire welding seam at the same time. Part tolerances can be melted off forming a welding bead, as both joining parts are pressed together during the welding process.
Characteristics and application:
- Laser beam focused to a spot
- Great flexibility
- Gap filling possible
- Suitable for small series and mass production
