[0002] In steel plate welding operations, a groove is usually made at the weld position of the steel plate after cutting to ensure full penetration. When making the groove, a flame cutting method is used to cut a groove bevel that meets the design angle on the thickness side of the steel plate, and then the groove bevel is polished to eliminate oxides on the groove bevel and defects such as pits formed during cutting, so that the groove surface presents a metallic luster to ensure the subsequent welding quality.

[0003] However, currently, the bevel is usually ground manually, using an angle grinder for grinding, or moving the bevel surface of the steel plate close to the grinder. Since most steel plates have bevels on all four sides, manual grinding around the four sides is more laborious, and it is difficult to ensure the stability of the moving steel plate, which results in high labor intensity, low efficiency, and low degree of automation.
