The 200mw laser pointer technology is good for developing new material

In aviation, international aviation engine business using a number of three-dimensional laser equipment burner section of the high-temperature alloy cutting and drilling tasks in military and civilian aircraft aluminum materials or special materials, green laser pointer cutting have been successful. Laser cutting is so widely used is because it has a good cutting quality, cutting speed, the working environment and good. Narrow width of the laser cutting incision (usually 0.1-0.5mm), high accuracy (typically hole center distance error 0.1-0.4mm, profile size error 0.1-0.5mm) incision in the surface roughness is good, (usually the surface roughness Ra of 12.5 ~ 25μm), cut joints generally do not need secondary processing to welding. Laser cutting of small heat-affected zone, minimal distortion, and clean, safe, pollution-free, greatly improving the operator's working environment.The  green laser pointer  technology has significant meaning on large-scale production and repair of integrated circuit. 2.1.2 Laser welding Laser welding laser is focused into a very thin to high energy density radiation beam to the workpiece, the workpiece heat melt, and then cooling the workpiece to be welded. Knot deep penetration laser welding, fast, efficient laser welding burn area narrow heat-affected zone is very small, very small deformation of the workpiece, while the weld is small, the structure can achieve uniform precision welding welding, small grain products, stomatal small, mixed small defects in the mechanical properties, corrosion resistance and electromagnetic performance superior to conventional welding methods. Laser welding in the mechanical processing of two typical applications in the automotive and welding with a large plate stitching gear. In order to meet the automotive industry wide steel plate and the needs of special features, laser welding of large plates by stitching, three-dimensional features of large automotive stamping plant requirements.The  green laser pointer  technology has development prospect in material modification. Global auto parts manufacturers have been achieved such laser welding applications. For example, Mercedes-Benz, BMW, Volkswagen, General Motors, Toyota, Opel, SAAB, Daimler - Chrysler, and many companies have already applied. 1m wide and can be cold-rolled steel, laser welding, makes up 2m wide plate. 3 laser welding arts gear work fundamentally changed the traditional concept of design and manufacturing, as part of the processing gear box type provides a better economy and a more compact structure. The use of laser welding gear technology, you need to process the entire ring long ring, then cut into a number of ring gear, and then were welded according to the requirements of the gearbox on the drive shaft. 2.1.3 Heat treatment is the use of laser heat treatment of high laser power density of laser beam on the metal surface treatment method. For example, when the metal surface heated to just below the melting point of the critical transition temperature, its surface quickly austenitizing and rapid quenching from the cold, metal surface quickly strengthened, that laser hardening. green laser pointer  technology is low in cost and easy in control. Laser surface heat treatment techniques include laser transformation hardening, laser coating technology, laser alloying, laser shock processing technology, these technologies to change the mechanical properties, heat resistance and corrosion resistance, etc. have an important role. Laser hardening can auto cylinder, piston rings, axle and other key parts for laser hardening process to significantly improve its performance in the laser heat treatment, without further post-processing, can be installed directly to the assembly line. U.S. General Motors Corporation was the first direct laser heat treatment technology to achieve good results in hardening of the cylinder wall, Germany's Volkswagen, Italy, Fiat, Therefore, the  200mw laser pointer technology is good for developing new material.Toyota and other Japanese manufacturers have a range of luxury cars will have this technology into the automobile production line, greatly improving the engine block wear resistance, and improved co-ordination of the cylinder block and piston rings, piston ring wear the same reduced.
