Green laser pointer has won everyone’s recognition

The  green laser pointer costumers are mainly teachers who work at the front of education. The 1970s mainly for welding thin materials and low-speed welding, the welding process is a thermal conductivity type, that is, laser radiation heating surface, the surface heat-driven heat transfer through the internal diffusion, by controlling the laser pulse width, energy, peak power and repetition rate other parameters, so that the workpiece melting, formation of a specific pool. Because of its unique advantages, have been successfully applied to micro, small parts precision welding. High-power high-power CO2 and YAG laser appeared, opened up a new field of laser welding. Effects obtained with the theoretical basis of the holes deep penetration welding, mechanical, automobile, steel and other industries to obtain an increasingly wide range of applications. Compared with other welding, laser welding of the main advantages are: 1, speed, depth, and deformation. 2, at room temperature or under special conditions, welding, welding equipment installation simple. The V105  green laser pointer has proved its value in the practice in the course.For example, the laser through the electromagnetic field, the beam does not shift; laser in a vacuum, air and a gas welding environment can, and can be glass or transparent material of the beam welding. 3, can be welded refractory materials such as titanium, quartz, and welding materials to the opposite sex, to good effect.green laser pointer has won everyone’s recognition
Obtained after focusing the laser beam by a small spot, and can accurately locate, can be applied to high-volume automated production of micro, small welding of the workpiece. 6, can be difficult to close the site welding, soldering the implementation of non-contact distance, with great flexibility. In particular, in recent years, the YAG laser processing technology uses fiber-optic transmission technology, the laser welding technology to obtain a wider range of promotion and application. 7, the laser beam is easy to achieve beam splitting by time and space, capable of simultaneously processing and multi-beam multi-station machining, welding to provide a more precise conditions.The V105  green laser pointer has proved its value by the splendid performance in the education practice. However, laser welding, there are also some limitations: 1, requires weldment assembly of high precision, and require the location of the beam on the workpiece can not significantly offset. This is because after the laser focus spot size is small, narrow weld, no additional filler metal materials. Such as parts assembly or precision beam positioning accuracy below standard, it is likely to cause weld defects. 2, the laser system and its associated high cost, one-time investment is large. 2 laser welding Laser welding is the thermal conductivity of high-intensity laser beam radiation to the metal surface by laser interaction with metal, the metal melt welding. The laser interaction with metals, metal melting is only one of the physical phenomena. Sometimes light is not primarily into metal melting, and in other forms, such as vaporization, plasma formation.
