What are the factors that affect the quality of flame cutting A36 plate

1. Control of cutting quality of various thickness A36 plates
According to different A36 plate thickness, different cutting speed, cutting gas pressure and cutting nozzle model should be adopted.
Before cutting the thick A36 plate, you should first try to cut the horizontal and vertical incisions, and then use a square to check the verticality of the cutting torch, so that the cutting surface can be perpendicular to the surface of A36 plate.

2. Control of cutting quality of A36 parts with holes
When cutting parts with holes, the inner hole of the part should be cut first, and then the 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 adjusting the speed and oxygen control valve; when the inner hole diameter is less than A36 plate thickness or A36 plate thickness exceeds 120mm, it is not suitable for perforation cutting.
