What is the principle of an automatic laser welding machine
The principle of an automatic laser welding machine : 1. The automatic laser welding machine drives the xenon lamp with high voltage to emit light. The YGA crystals installed together are illuminated by the laser, resonate through the total reflection and semi-reflection diaphragm, and then input to the optical fiber through the splitter and shutter, and finally focus the laser to a point 2. The power density on the focal plane can reach 10 5 -1013 w/cm2. The laser welding machine uses the excellent directivity and high power density of the laser beam to work. Through the optical system 3. Concentrate the laser beam of the automatic laser welding machine in a small area, in a very short time, making the welded place form a highly concentrated local heat source area so that the welded object will melt and form a firm welding spot and Weld. Laser welding can be realized by a continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and la
