Automatic laser welding machine is a very mainstream automatic welding equipment at this stage, and many manufacturers will use it. However, it is very necessary to have a corresponding understanding of the machinery and equipment in the use and operation of daily life, because in order to make better use of the machinery and equipment, it is necessary to have a corresponding understanding of the operating methods of various parts of the machinery and equipment. Next, we will discuss with Xiao Bian what is the principle of the automatic laser welding machine!
What is the principle of automatic laser welding machine
1. The automatic laser welding machine drives the xenon lamp to glow under high voltage. The YGA crystal assembled in one piece is illuminated by the laser. It is resonated by the full reverse and semi reverse diaphragms, and then transmitted to the optical fiber through the splitter and shutter, finally gathering the laser to one point
2. The power density on the focal plane can reach 105-1013w/cm2. The laser welding machine makes full use of the good directivity and high power density of the laser beam to operate. Through optical system
3. Gather the laser beam of the automatic laser welding machine in a small range, and in a very short period of time, form a local heat source area with highly concentrated energy at the place to be welded, thus melting the object to be welded and forming a solid welding spot and weld.
Laser welding can be realized by continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. When the power density is less than 104~105 W/cm2, it is heat conduction welding. At this moment, the penetration is shallow and the welding speed is relatively slow; When the power density is greater than 105~107 W/cm2, the metal surface is concave into "holes" under the action of heat, forming deep penetration welding, which is characterized by faster welding speed and large depth width ratio. Have you got a preliminary understanding of the principle of automatic laser welding machine after reading the above contents? You can also discuss more about the operation of the automatic laser welding machine. In the end, correct and reasonable operation is the first step in processing and production!
