Benefits and advantages of automotive laser welding machines

Laser welding has become one of the important means in industrial manufacturing because of its high energy density, small deformation, narrow heat affected zone, fast welding speed, easy automatic control and no subsequent processing, especially in the automotive industry. Laser welding machine technology increases production efficiency for the automotive industry and brings significant economic benefits to the automotive industry.

The automotive industry adopt a large number of laser-welded steel sheets and unequal-thickness steel plates, make full use of the excellent properties of laser weld seam. After welding, the stamping forming will not have cracking. On the one hand, for the steel parts with insufficient width, because the different parts of the car body have different force condition, and the requirements on strength and rigidity are also different. In order to reduce the weight of the car body, different thickness, different kinds of steel or different surface treatment methods are often selected according to the actual needs of each part to be welded together by laser, as the blank before stamping.

The automobile laser welding machine pulse discharges the xenon lamp by the laser power source to form a light wave with a certain frequency and a certain pulse width. The light wave is radiated to the Nd3+:YAG laser crystal through the cavity, and the Nd3+:YAG laser crystal is stimulated to emit light, then after the resonance by laser resonant cavity, a pulsed laser with wavelength of 1064 nm is emitted, and the pulsed laser is focused on the object to be welded after being focused, reflected, or (transmitted by optical fiber transmission), to complete the welding under the control of PLC or industrial PC.

Compared with the traditional welding process, the laser welding machine can process various materials on the automobile, improve the overall performance of the car, reduce the production cost and improve the production efficiency.

Shenzhen Sun Laser's automotive laser welding machine welds auto parts to directly reduce the weight of the car body, improve the assembly accuracy of the car body, increase the rigidity and firmness of the car, greatly reduce the cost of the car body and accessories in the manufacturing process, and reduce the manufacturing cost of the car.
