Gears are an indispensable part of the car's construction. In the manufacture of automobile transmission gears, in order to reduce the difficulty of gear hot working and cold working, and to improve production efficiency, the gears are often divided into two separate parts for processing, and then the two parts are combined to form a whole. Form a composite gear.

There are two main ways to connect a compound gear: a spline connection and a beam welding connection. The spline connection is realized by the inner and outer splines, the empty sipe is large, the axial dimension of the gear is large, and the production efficiency.

The beam welding connection is mainly laser welding. The laser welding technology is used to connect the gears. The depth of the weld of the gear is relatively large, the deformation of the welding gear is small, and the welding strength is high.
The gears for automobiles require a relatively large width of the weld, and no defects such as pits are allowed at the joints between the first and the last. Therefore, the laser welding machine is more suitable for welding gears.

Welding the gear with a laser welding machine can improve the product precision of the gear, simplify the product structure and manufacturing process, and can easily meet the needs of the continuous adjustment of the component structure and the manufacture of the prototype in the product development and trial production.
The geared laser welding machine developed by Perfect Laser has a compact structure, high precision and high reliability, which can reduce the vehicle failure rate, improve the operational flexibility of the vehicle and improve the reputation of the product.
