The approval of manufacturing laser pointer is not that hard to gain.
Laser welding method compared with conventional suture, laser welding with consistent speed, no foreign body reaction in the healing process, to maintain the mechanical properties of welded joints was the original repair tissue biomechanical properties of their advantages in the future growth of the biomedical be more widely used. In other industries, laser welding is also increasing, especially in the welding of special materials for a number of national studies, such as BT20 titanium alloy, HEl30 alloys, Li-ion batteries, such as laser welding, the German glass machinery manufacturers Glamaco Coswig with IFW Experimental techniques and materials joining Research Institute developed a new laser welding for flat glass technology. Automated monitoring of laser welding is one of the key real-time monitoring weld pool, so the choice of tracking sensors has become a vital prerequisite. In all sensors, optical sensors for its high sensitivity and measurement accuracy, the dynamic characteristics of a good, no contact with the workpiece and the large amount of information contained in such features as the fastest growing track sensors, and CCD (Charge-coupled Device Charge Coupled device) the application of integrated optical devices and optical sensor makes the sensor up to a new height of the video. The customer should pay attention to the safety consideration of laser pointer .Laser welding filler wire used as the alloy composition can select any of the weld wire as the best transition alloy, thereby ensuring both sides of the base material of the coupling with the best performance. Can high melting point, high thermal conductivity, large differences in the physical properties of heterogeneous materials or of the same metal welding, can be non-polluting, less impurities in the weld. Heating laser welding speed, rapid cooling weld pool, and common in conventional welding on microstructure differs significantly. Laser welding (Tailored Bland Laser Welding) technology in the foreign car manufacturers in the widely used, according to statistics, in 2000 worldwide production of laser welded tailored blanks more than 100 lines, annual output of cars tailor-welded blanks components 70 million and continue at a higher rate. The introduction of domestic production models Passat, Buick, Audi, also adopted a number of cut blanks structure. Japan CO2 laser for flash butt welding instead of rolling sheet steel industry connections, the thin plate welding research, such as thickness of 100 microns or less foil, not welded, but through a special output waveform of the YAG the success of laser welding, laser welding shows a broad future. Figure 1 shows the radiated power density in the different evolution of the next stage of the melting process, there are two kinds of laser welding mechanism: As the laser light in the material surface, part Jiguang is reflected in part by material absorption, the light energy into heat energy and heating melted surface layer of heat to heat conduction material way to the depths to pass, and finally welding the two pieces welded together.
