green laser pointer improves the working efficiency

Volume is essential. 4, the laser welding process ⑶ laser welding laser welding machine is high-intensity laser beam radiation to the metal surface, the laser welding is the high-intensity laser beam radiation to the metal surface by laser interaction with metal, weld the metal to melt.
Spot, and can accurately locate, can be applied to high-volume automated production of micro-welding of small parts of the group. 3, the laser welding equipment o often referred to as laser welding, laser welding machine, according to their work often can be divided into mold burning laser welding laser welding, laser welding, manual welding machine), automatic laser welding laser spot welding, laser welding optical fiber transmission, etc.), automatic laser welding (manual welding machine), automatic laser welding, laser spot welding, laser welding, etc.The green laser pointer could help users to solve tough operational problems in physical space. ⑹ optical fiber transmission inaccessible parts can be welded, implementation of long-range non-contact welding, a very inaccessible parts can be welded, the implementation of long-range non-contact welding, a large flexibility. Of 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. However, laser welding, there are also some limitations: However, laser welding, there are also some limitations: ⑴ weldment assembly requires high precision, and require the location of the beam on the workpiece can not have the required high precision weldment assembly, significantly the offset. A significant shift. This is because after the laser focus spot size is small, narrow weld, without filler metal materials.So the green laser pointer improves the working efficiency. If the workpiece assembly precision beam positioning accuracy or fail to meet requirements, it is likely to cause weld defects. ⑵ lasers and their associated high cost of the system, a one-time investment is large. Lasers and their associated high cost of the system, a one-time investment is large. 10 laser welding equipment mainly by lasers, optical systems, welding machines and control system components. Mainly by the laser welding equipment, laser, optical systems, welding machines and control system. Laser gas lasers and YAG lasers ⑴ solid-state laser two. YAG solid-state lasers used in laser welding two kinds of main CO2 gas laser and YAG solid-state laser two. Comparison between the advantages and disadvantages as shown in Table 1. The most important properties of the laser output power and beam quality is. green laser pointer totally set users free from restriction in teaching demonstration.YAG laser is the most important performance laser output power and beam quality. Guide light focusing optical system focusing system consists of circularly polarized beam expander lens, mirror or fiber optic, circular polarizers, optical focusing system consists of circular polarizers, beam expander, mirrors or fiber, focusing lens and other components, to achieve change the beam polarization state, direction, etc. transmit and focus the beam to achieve the change in beam polarization state, the direction of the function. The function. These optical components for laser welding conditions are extremely important impact on quality. These optical components for laser welding conditions are extremely important impact on quality. Role in high-power laser, optical components, in the role of high-power laser, optical components, especially the deterioration of the transmittance of the lens performance will decline; will have a thermal lens effect (the transmittance decreased; will produce thermal lensing ( reduced thermal expansion of the lens focal length); surface contamination will increase transmission loss.); surface contamination will increase transmission loss. With green laser pointer, you control the computer at any corner of the classroom.Surface contamination will increase the transmission loss so the quality of optical components, so the quality of optical components, maintenance and condition monitoring work is essential for ensuring the quality of welding.
