Gas Pressure Control of Fastflow Axis High Power CO_2 Lasor

In industrial laser processing,there are many factors to affect the quality such as laser mode, power density,stability of the power and so on. In laser cutting,the fastflow axis CO 2 laser is often used because of its good laser beam quality.Keeping the working gas at optimal point and keeping its stability is the key problem of stability of laser power. This paper applies PID with intelligent integral separation to adjust the pressure of the working gas. With this simple and practical algorithm,the gas control precision is improved. Ultimately,the power precision and stability can be ensured. All above is verified by the experiments.
