Jewelry laser spot welding machine, it is a kind of laser welding machine specially manufactured and produced for products such as jewelry.
Principle of jewelry laser welding machine
The surface of the metal will undergo a series of changes under the action of the laser, and the surface will be heated by the laser and quickly conduct as the depth. When the laser power density is constant, the surface will melt, and part of it will be instantly vaporized when the laser power density is high. A molten pool is formed on the surface of the workpiece. During the welding process, the workpiece moves relative to the laser, so that the molten metal accelerates along a certain angle, the heat transfer temperature of the liquid metal decreases rapidly, and the liquid metal forms a weld.
The jewelry laser welding machine equipment belongs to the pulse welding method. The pulse energy and pulse width are adjustable during welding. The pulse energy affects the melting amount and the width affects the melting depth. At the same time, the size of the welding spot is adjusted by adjusting the focused spot through the adjustable beam expander of the external optical path. Compared with other welding processes, laser welding can realize the welding of many materials, and has advantages in comparison. The thermal deformation of the welded components is small, and the quality of the joints is high.
The laser welding machine adopts ceramic concentrating cavity, which is corrosion-resistant, high-temperature resistant, high photoelectric conversion efficiency, long life of the concentrating cavity, and long life of the xenon lamp; the output protective gas ensures that the solder joints are beautiful, and the solder joints will not be oxidized and discolored. Continuous working ability, stable working performance of the whole machine. The advantage of laser welding is that it can realize local small-scale heating characteristics, and it is widely used in jewelry, batteries, mobile phone parts and other industries.
