With the further development of automotive safety technology, it is now required to install curtain airbags on the side of the seat, that is, above the door, to protect the car from side impact or rollover. The laser welding machine for automobile safety airbag has the remarkable advantages of high efficiency, convenient energy transfer, joint degeneration after welding, less deformation, and smooth surface, and the weld is uniform, which can integrate heterogeneous materials. Since the late 1980s, kilowatt laser was successfully applied to industrial production, and now the laser welding production line has appeared in the automobile manufacturing industry on a large scale, becoming one of the outstanding achievements of the automobile manufacturing industry.
The main components of airbag are collision sensor, control module, gas generator and airbag. Due to the high strength requirements of air bags and the unique advantages of laser welding technology, laser welded stainless steel or high-strength structural steel gas generator shells are used in succession. The gas generator of the automobile airbag under laser welding is welded by using local heating. The workpiece is not easy to produce thermal damage and deformation. The bonding strength is high, and the water resistance pressure reaches 70MPa (depending on the material), with high safety and reliability; Since the temperature will not rise when welding the shell of the automobile airbag, the shell can be welded after the gas generating agent is filled, and the welding process is very safe.
Features of laser welding machine for automobile airbag:
1.The weld penetration is large, which can reach 2~3mm. The welding strength is high, the heat affected zone is small, and the welding deformation is small;
2.High degree of automation, easy to control and fast;
3.The laser welding machine for automobile airbag has high welding precision, good stability of repeated operation and high yield;
4.Non contact processing, no welding auxiliary tools required;
5.The laser welding machine for automobile airbag does not need welding rods or filler materials, and the welding seam is free of impurities, pollution and good quality.
The above is the technology of laser welding machine in welding airbag, which can really make a great contribution to our automobile industry. Now laser welding technology has spread in the automobile industry, solving the bottleneck of the automobile industry in the past. The emergence of new processing technology will certainly promote the progress of the industry. I believe that the application of laser technology will be more extensive in the future.
