Early automotive clutches are used in the overall processing of medium-carbon steel, overall quenching, or overall processing of low carbon steel, carburizing quenching. These two processes are time-consuming, costly, easy to wear, deform and tear of the connecting parts. Since the early 1980s, it has been changed to component processing and the clutch plate use carburizing quenching, while the connecting sleeve is tempered and the two pieces in the press-fit after the use of laser welding.

Advantages of laser welding machines for automotive clutch manufacturing:

1、High power and high density after laser focusing. The focal spot diameter of the high power laser is small after focusing.

2、Laser welding is faster, deeper and less deformed.Due to the high power density, small holes are created in the metal material during the laser welding process. The laser energy is transmitted through the small holes to the deeper part of the workpiece with less lateral diffusion, resulting in a large depth of fusion of the material during a single scan of the laser beam, a fast welding speed, and a large welded area per unit of time.

3、Large welding depth-to-width ratio, small specific energy, small heat-affected zone, small welding deformation is specially suitable for precision and heat-sensitive parts welding. Post-weld straightening and secondary processing can be eliminated.

4、Laser welding is similar to E-beam welding in many ways and laser welding quality is slightly lower than E-beam welding. However, electron beams can only be transmitted in a vacuum, so welding can only be performed in a vacuum, whereas laser welding technology can be applied in a much wider range of working environments.

5、It can weld refractory materials, such as titanium, etc., and can weld different materials.For example, copper and tantalum, two metals with very different properties, are soldered together with good results.

6、Can weld hard-to-reach parts and can weld non-contact over long distances with great flexibility.

7、Micro-welding is possible.The laser beam can be focused to obtain a very small spot, and can be precisely positioned, and can be applied to high-volume automated production of micro and small components in the group welding.Not only the production efficiency is greatly improved, but also the heat-affected zone is small, the welded joint is not contaminated, and the quality of welding is greatly improved.

These are the characteristics of the laser welding machine in the manufacture of automotive clutches. Laser welding is superior to other welding methods in terms of welding efficiency, weld quality and material utilization.As a result, laser welding is widely used in the automotive industry. Laser welding can be used for welding automotive parts such as exhaust emission systems, transmission duplex gears, shock absorber oil storage cylinder barrels and filters, etc. It can also be used for the welding of automobile bodywork and automobile body frames.While improving the structural strength and production efficiency of automobiles, it reduces the overall vehicle quality and production costs, bringing significant economic benefits to the automotive industry.
