Korea pieces of assembly quality demanding, non-vacuum electron beam welding can also be implemented, but bad due to electron scattering and focusing effects. Of electron beam welding, as well as magnetic offset and X-ray, due to the electronic charged will be affected by a magnetic field affect, and called for the electron beam welder welding to go magnetic treatment. X-rays under high pressure is particularly strong need to protect the operator. Laser welding without the vacuum chamber and to the magnetic treatment of the workpiece before welding, it can be in the atmosphere, there is no anti-X-ray, so the online operation in the production line can also be welded magnetic materials. Laser welding applications in sensor production prospects. Laser welding technology is a high-tech. laser pointer pen The power of laser pointer pen fluctuates at 50mW.
Due to its unique characteristics, especially suitable for use in the sensor seal welding, many foreign manufacturers of the production sensors use laser welding process to produce sensor, while the domestic use of the small manufacturers of this technology, mainly the production of military sensor products manufacturers and some research institutions in the use of such technology, and the use of foreign laser welding machine more. Domestic laser welding machine performance and foreign products, not far off, fully capable of the domestic production process requirements of the sensor, but the price is 1/3-1/5 of the similar foreign products. In order to improve the overall level of domestic sensors and the development of national laser industry. If the power of laser pointer pen is fixed.
Sensor manufacturers in China made laser welding machine should be adopted as soon as possible to production and processing sensor, in order to increase the competitiveness of their products, explore the international market. Laser Precision Machining Technology Status and Prospects. Very wide scope of laser material processing, sintering, drilling, marking, cutting, welding, surface modification and chemical vapor deposition and so has the laser as an essential energy. The laser beam can be focused to very small size, which is particularly suitable for precision machining. Our requirements in accordance with the size of the processed materials and precision machining, laser processing technology is divided into three levels: large pieces of material laser processing technology to the plate (a few millimeters to tens of millimeters), the machining accuracy usually in the millimeter or submillimeter. Then this kind of laser pointer pen can not be used to burn the match. Laser Pointers
Precision laser processing technology to the sheet (0.1 to 1.0 mm) as the main processing, machining accuracy is generally in the 10 micron; laser micromachining technology as the main processing for a variety of film thickness below 100?m, Its precision is generally less than ten microns or even sub-micron level. It must be noted that, in the machinery industry, precision usually refers to the surface roughness is small, a variety of tolerance (including the location, shape, size, etc.) range. However, this article called “precision” refers to be machined area of the gap is small, the small size of the limit This means that processing can be achieved. In the above three types of laser processing, large-scale laser processing technology matures, the degree of industrialization has been very high, there are a lot of literature were reviewed. For this kind oflaser pointer pen can not burn the match.
Laser microfabrication techniques such as laser trimming, precision laser etching, laser direct-write technology in the industry has been more widely used, the overview has also been reported more; this article will focus on discussion of laser precision machining technology. The processing object for more convenient, precision machining mentioned below is limited to sheet (0.1-0.1mm). Comparison of laser precision machining and traditional processing methods. As technology advances, the types of precision machining technology has become increasingly diverse. The laser precision machining has the following significant features: a wide range of laser precision machining object, including almost all metallic materials and nonmetallic materials. The electrolytic processing can only be processed conductive material. Or we can say laser pointer pen has no ability to burn the match.
