The safety consideration of green laser pointer

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 in the production of sensors applications. Laser welding technology is a high-tech, 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. The good equipment can ensure the high output of green laser pointer.
Domestic manufacturers of this technology is small, mainly 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. Sensor manufacturers to improve the overall level of domestic sensors and the development of national laser industry in China made laser welding machine as soon as possible to production and processing sensor, in order to increase the competitiveness of their products, explore the international market. The drawing of green laser pointer is one of the inspection items.
Laser welding technology and its application in the automotive laser welding from the 1960s laser was born soon began to study welding from the beginning of the thin parts or devices to high-power laser welding in industrial production of a large number of applications, has experienced nearly 40 years of development. Laser welding with high energy density, deformation is small, narrow heat-affected zone, high welding speed, easy to implement automatic control, without subsequent processing advantages, is becoming an important means of metal processing and manufacturing in recent years, more and more widely materials involved in the field of automotive, aerospace, defense industry, shipbuilding, marine engineering, nuclear power equipment, etc., covering almost all metallic materials. Some new rules are made for green laser pointer.
Compared with traditional welding methods, laser welding, there are still expensive equipment, one-time investment, technically demanding, laser welding in industrial applications in China is still quite limited, but the laser welding productivity high and easy to achieve automatic control characteristics that make it very suitable for large-scale production lines and flexible manufacturing. Among them, many of the successful application of laser welding in the field of automobile manufacturing has highlighted the features and advantages of laser welding is different from traditional welding methods, but also for many high power laser manufacturers and laser welding equipment manufacturers to provide a more attractive economic Benefit prospects. This is also the laser welding to be able to attract more and more domestic and foreign scientific and technical personnel engaged in research and technology development. The drawing of green laser pointer contains a lot of information.
This paper reviews recent progress in research and application of laser welding technology at home and abroad, and describes the typical applications of laser welding in the field of automotive parts and body manufacturing. High-power lasers widely used in automobile manufacturing and other industrial production including two types of CO2 lasers and of Nd3 +: YAG laser, high-power semiconductor lasers in the welding field of research is still in its infancy. CO2 laser used for penetration laser welding is generally continuous manner, including the fast-axial flow and Slab are two types. Slab laser with a compact, less gas consumption, maintenance and low cost compared with fast axial flow lasers. The parameter on the drawing of green laser pointer should be accurate.
