Laser-welding means that light is concentrated on a miniature focal point. The energy generated is extremely dense – the material to be welded melts within a blink. The seam cools down equally fast and becomes immensely strong immediately. This means that the component itself is not much stressed mechanically, and you obtain a clean welding seam from a reliable process which does not damage the machined component.
Laser-welding processes are mostly used for the joining of components requiring narrow welding seam shapes and low thermally-induced warping. The impressive benefits are: high welding speeds, excellent automation potential, and the option of an in-process Online quality inspection.
