It is the laser remote control of the emitters of green laser pointer
It is a new type of welding can be achieved for the welding of thin-walled materials, precision parts, spot welding, butt welding, stitch welding, seal welding, deep wide than high, the weld width of the small, small heat affected zone. small deformation, welding speed, weld formation, appearance, after welding without having to deal with, or simply deal with high-quality welds, no porosity can be precisely controlled, the focused spot small, high positioning accuracy, easy to automate. Laser welding is one of the important aspects of laser material processing applications. The 1970s is mainly used for welding thin-walled materials and low-speed welding, the welding process is a thermal conductivity type, the laser radiation heating the surface, the surface of the heat through the heat transfer-oriented internal diffusion. It is according to the specific procedure of producing green laser pointer .
Control the parameters of the laser pulse width, energy, peak power and repetition rate of the workpiece to melt, the formation of specific bath. Because of its unique advantages, have been successfully applied in the micro, precision welding of small parts. The emergence of high-power CO2 and high-power YAG lasers, has opened up new areas for laser welding. To obtain deep penetration welding, to the effect of holes as the theoretical basis and increasingly widely used in machinery, automobile, steel and other industrial areas. Compared with other welding technology, laser welding of the main advantages are: speed, depth, small deformation. Room temperature or under special conditions, welding, welding equipment device is simple. For example, the laser through the electromagnetic field, the beam will not be offset. To meet the high requirements and various needs of the customer of laser pointer .
Laser welding in vacuum, air and environment of a gas can, and through the glass or transparent material on the beam welding. Welding of refractory materials such as titanium, quartz, and welding the opposite sex material to good effect. Laser focus, high power density welding of high-power devices, the aspect ratios up to 5:1 up to 10:1. Can be micro-welding. Available by focusing a small laser beam spot, and can precise positioning can be applied to the automated production of large quantities of micro, small parts welding. Welding can be difficult to close the site, the implementation of long-distance non-contact welding, and has great flexibility. In recent years, the YAG laser processing technology using a fiber optic transmission technology. All parts and components of green laser should be purchased from the qualified supplier.
Access to a wider range of promotion and application of laser welding technology. The laser beam is easy to realize the beam splitter according to time and space, at the same time processing of multi-beam and multi-bit processing, provided the conditions for more precise welding. Laser welding, however, there are some limitations: the requirements of the weldment assembly of high precision, and the requirements of the position of the beam on the workpiece can not have a significant offset. This is because the laser focus spot size is small, narrow weld, not add filler metal materials. Such as workpiece assembly precision beam positioning accuracy is below standard, it is easy to weld defects. Lasers and their associated systems, high cost, one-time investment. Laser welding heat conduction. And the incoming test of the raw material of green laser pointer should be performed.
