Powertrain
Joining components using laser technology makes the way free for innovative designs. Weight optimization and emission reduction with simultaneously increased torque transmission are important development goals for the automotive industry. Laser technology is the drive for new paths in welding, cutting and inscribing technology. The following gear components are only a few examples of established applications.
The case-hardened crown gear is welded to the cast iron housing. Laser welding replaces the screw connection used earlier. This reduces production costs, component weight previously and component size.
The laser welds the lamellae support to hub parts. This yields the compact construction of today's modern dual-clutch designs. They are fabricated with a short cycle time and little warp. Up to 12 welds per dual clutch are the standard today.
Formed sheet metal parts in combination with rotating parts are welded by the laser with little warping and a short cycle time.
Dual-weighted flywheels are "oscillation-damping units" in the automobile. They reduce the oscillations inevitable in any internal combustion engine, thus increasing the comfort of the vehicle. The laser seals the housing and welds the hardened ignition gear with little warping.
The tripod and end piece of high-carbon steels are pressed with a pipe and welded with the laser. There is little warping, so part length tolerances are maintained. The choice of material supports an inductive preheating and post-heating process.
