[0002] Weathering steel, also known as weathering steel, is an alloy steel formed by adding a certain amount of alloy composition to ordinary steel. It has good heat resistance and corrosion resistance. Pipes made of weathering steel need to be cut to a suitable length using a laser cutting machine during processing; in the prior art, the utility model patent with patent application number 202320534926.3 discloses a laser pipe cutting machine, which is mainly composed of a support device, a bracket and a laser cutting head. When it is used, the pipe to be cut is fixed by the support device, and then the pipe is cut by the laser cutting head on the bracket; the inventor believes that there are the following problems in its use. Since the laser cutting head is fixedly mounted on the bracket, its height cannot be adjusted. When cutting pipes of different diameters, the distance between the laser cutting head and the pipe is inconsistent. It cannot adjust the height of the laser cutting head according to the diameter of the pipe, which makes it inconvenient to use, has high limitations in use, and has low practicality.
