According to different thickness of ASTM A131 DH36 steel plate, different cutting speed, cutting gas pressure and cutting nozzle type should be adopted.Before cutting ASTM A131 DH36 steel plate, transverse and longitudinal incisions should be made, and then checked with a square to adjust the verticality of the cutting torch, so that the cutting surface can be perpendicular to the surface of ASTM A131 DH36 steel plate.
Cutting quality control of ASTM A131 DH36 steel plate with hole：When cutting parts with holes, the inner hole of the part should be cut first, and then cut its periphery. The purpose of this is to ensure the dimensional accuracy of the inner hole and the periphery.
When perforating, choose a reasonable perforation point, pay attention to adjust the speed and oxygen control valve. When the diameter of the inner hole is less than the thickness of ASTM A131 DH36 steel plate or more than 120mm, it is not suitable to perforate cutting.
