The meeting is to discuss the quality problem of  green laser pointer .
With the birth of a new generation of lasers, the laser's life span can reach 50000h, which greatly reduces the cost of the use of laser welding equipment. However, in order to obtain the desired quality of welding, gas protection is essential, which also caused the increase in processing costs; laser welding depth to width ratio is less than the electron beam welding, is generally less than 10:1 (in the gear laser welding the weld depth of 4 to 6 mm, and therefore this aspect is still relatively applicable), not suitable for the welding of large thickness of the workpiece; laser welding of aluminum alloy and other high-reflectivity materials welding there are still some technical difficulties, we must filler wire and other auxiliary means, in order to achieve better welding effect.  green laser pointer can be used by the customer to point to the star.

This kind of green laser pointer can meet the special requirement

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 used in fiber optic transmission technology, access to a wider range of promotion and application of laser welding technology. The laser range of this kind of green laser pointer can meet the special requirement.
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-foot rain-inch weld narrow, the filler metal materials. If the workpiece assembly precision beam positioning accuracy is below standard, it is likely to cause welding defects. Lasers and their associated systems, high cost, one-time investment. Laser welding heat conduction. Laser welding is a high-intensity laser beam radiation to the metal surface through the interaction of laser and metal, the metal melt formed welding.  green laser pointer used for the star gazing can be the green laser pointer.It is the wavelength of 635 nm and 650 nm of  green laser pointer 
Laser and metal interaction process, the metal melt is only one of the physical phenomena. Sometimes the light is not mainly converted into metal melting, and other forms of performance, such as vaporization, plasma formation. However, to achieve a good molten weld metal melt to become the main form of energy conversion. Therefore, we must understand the various physical phenomena arising from the interaction between laser and metal as well as the relationship of these physical phenomena and laser parameters, and thus by controlling the laser parameters, the laser energy is mostly converted into the energy of the molten metal to reach welding purpose. Therefore, the good effect of green laser pointer for the star gazing can be realized.
