With the continuous development of laser technology, laser tube cutting machines have gradually become the preferred choice for steel tube cutting and processing due to their characteristics of high efficiency, precision, and flexibility. This solution uses a laser tube cutting machine to cut steel tubes of 3 m to 6 m with different diameters into equal-length sections and cut specified patterns (such as round hole and square hole) on the tube wall. It can also perform bevel cutting to meet special processing requirements such as right-angle welding of two steel tubes.
