Paper Abstract

Aiming to the special high power CO2 laser surface treatment, the paper developed the integrated control system based on S7-200 PLC of transverse flow CO2 laser. The selection of key technology and components, detection and control of signals, integrated control of complete circuit, technology of human machine interface and process control of system have been researched. Double closed loop power control system was realized, so that the stability of the laser power was in ±2%. Also, the giving power can be controlled by the laser controller or by the processing machine, thus, the users can control the laser more efficiently when processing. A series of experiments have been performed on 5kW transverse flow CO2 laser, the output laser power was stable at discharge current of 9A for 8 hours, and the maximal power was 5.42 kW. The new type of transverse flow CO2 Laser with Integrated Control System has been applied for special laser cladding with power-modulating on the metallic surface of the oil industry production.
