Laser Welding Machine Working Principle

The xenon lamp is driven by high voltage to emit light. The YGA crystal installed together is irradiated by the laser. It is resonated by the total reflection and half reflection diaphragms, and then input to the optical fiber through the beam splitter and shutter. Finally, the laser is focused to a point. The power density on the focal plane can reach 105-1013 w / cm2. Laser welding machine works by using the excellent directivity and high power density of laser beam. The laser beam is concentrated in a small area through the optical system, and in a very short time, a local heat source area with high energy concentration is formed at the welded place, so that the welded object is melted and a solid welding spot and weld seam are formed.
