Description

Technical Field

[0002] Laser cutting technology uses a high-power laser beam to irradiate the material to achieve rapid melting, evaporation or combustion of the material, and uses a high-speed airflow coaxial with the laser to remove the molten material, thereby achieving material cutting. This cutting method is fast and efficient, and has a small heat-affected area on the material. It has become an important cutting method in pipe processing and has been widely used in the field of pipe processing.
