LASER WELDING is unique since it offers non-contact autogenous WELDING process that is not affected by the electrical conductivity or magnetic properties of the materials being welded. Lasers can be used in PULSED or CW (Continuous Wave) mode. In PULSED mode, LASER welds are similar to resistance spot WELDING and in CW mode they are similar to arc WELDING processes. While CW mode is common for larger structural welds and competes with arc WELDING processes, PULSED WELDING is common for welds in smaller components such as pacemakers, microwave enclosures, batteries, and sensors.
