Research on laser cutting process of thin stainless steel plates
Effect of cutting gas pressure on cutting quality When laser cutting, different cutting gases are selected according to the material of the cutting plate. Nitrogen is mainly used to cut stainless steel. The selection of cutting gas and its pressure has a great impact on the quality of laser cutting. The main functions of cutting gas include: supporting combustion and dissipating heat, promptly blowing off molten stains produced by cutting, preventing molten stains from rebounding upward into the nozzle, protecting the focusing lens, etc. The experiment adopts the controlled variable method, the cutting speed is set to 8m/min, the focus position of the laser focus is -0.5mm, and the air […]
