Laser welding is characterized by minimal deformation of the workpiece to be welded, almost no connection gap, weld depth / width is high, so the welding quality than traditional welding methods. However, to guarantee the quality of laser welding, laser welding process monitoring and quality control is an important content of a field of laser use, including the use of inductive, capacitive, acoustic, photoelectric sensors, computer processing, for different welding objects and requirements, such as seam tracking, defect detection, weld quality monitoring, and feedback control to adjust the welding parameters in order to achieve the automation of laser welding. This kind ofgreen laser pointeris in the pen shape.
In laser welding, the beam focus position is one of the most critical control process parameters, in a certain laser power and welding speed, only the focus is within the best position to get maximum penetration and good weld shape. The actual laser welding, in order to avoid and reduce the factors affecting the stability of the focus position, the need for special clamping device technology, the degree of precision of this equipment and the quality level of the laser welding are complementary. The main features of laser welding. Compared with other conventional welding techniques, laser welding of the main advantages are: speed, depth, small deformation. Room temperature or under special conditions, welding, welding equipment device is simple. The output power ofgreen laser pointeris 100mW.
For example, the laser through the electromagnetic field, the beam will not be offset; laser welding can vacuum, air and a gas environment, 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. The laser light of green laser pointer is clearly visible in the dark night.
In recent years, the YAG laser processing technology uses a fiber optic transmission technology, 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-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. green laser pointer is definitely a good tool and assistant.
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. 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. The chip ofgreen laser pointer has the life time as long as 8000 hours.
