The smooth working of laser pointer should be ensured at first.
Laser beam can be together very fine, high energy density beam, almost all of the materials can be gasified, with broad applicability; laser power control, easy to automate; laser beam power density is high, large weld penetration speed, high efficiency; narrow laser weld heat-affected zone is very small, very small deformation of the workpiece can be achieved precision welding; laser weld uniform, grain very small, less porosity, inclusions few defects in the mechanical properties, corrosion resistance and electromagnetic performance superior to conventional welding methods. Laser - arc complex is the primary means of laser welding, laser interaction with the electric arc to produce a good composite effect. Deep penetration welding, the laser-produced plasma is conducive to the stability of the arc; can improve processing efficiency; can improve poor welding materials such as aluminum, dual-phase steel weldability; increase the stability and reliability of welding. The technology adopting of laser pointer is the main topic of the meeting.
Laser welding technology: increase the number of aluminum body, will accelerate the laser welding applications in automotive manufacturing. Audi A2 cars all-aluminum body components using laser welding, the weld total length of 30m. The use of laser welding of aluminum materials, the main advantages are: welding speed. And compared to traditional body welding technology by laser welding parts, better strength and rigidity. In addition, laser welding can be saved welding flanges, which undoubtedly can reduce material consumption, help the car's own weight down. Laser welding can make aluminum sheet and aluminum sheet (pieces) connection between, also make the aluminum sheet (pieces) to link with aluminum castings. The technical reform of laser pointer should be considered at first.
Another application is the transmission of plastic parts for laser beam welding. Such as a transparent plastic parts with another filling material with adsorption to link the plastic parts. Laser beam through the upper transparent plastic, so that the lower connector instantly melt through the melting expansion and the partial melting on the wet parts, upper and lower parts are welded together. BLZ developed an airbag control unit (plastic) case the laser beam transmission welding technology, using the diode laser, compared with conventional welding techniques, not only the high process flexibility, but very few electronic components produced by the welding process mechanical and thermal damage. laser pointer has been well tested.
