Analysis Of Laser Welder Clamping Unit Control System

In the high precision laser welding, the servo technology is very common. It is also used in the Miebach laser welding clamp table servo control system. In the traditional welder, the welding clamping control system about moving parts usually consists of two hydraulic actuators by a group of same parameters. However, caused by the machining error, the parameters of each actuator configuration will be a little different, and it will produce a clamp force dispute, and affect control performance and accuracy, and even reliability thereby.In this paper, Miebach laser welding clamp control system will be modeled by using of Matlab / Simulink .The simulation results show that: Caused by different factors, if the characteristic of two drive system are not the same, it will lead to produce the force dispute phenomenon in the welding clamp control system. Then, we compare several solutions to deal with the feasibility and effectiveness of the force dispute through simulation studies.
