Polaris adds laser wobble technology

Laser wobble has been added to Polaris Motion’s laser CNC toolbox. The laser wobble technique can improve laser welding, cutting, engraving and marking. By using wobble-based laser welding, a smaller spot size may be selected having higher fluence and the effective size of the liquid weld pool is determined by the wobble dimensions and frequency. This added control leads to high weld quality by maximizing contact between the workpieces and providing improved weld cross section, improved tolerance to gap variability and improved seam alignment.
