q345b steel sheet structural steel pipe

When automatic steel plate cutting is carried out, the distance difference between the steel plate hanging from the steel plate to the gas cutting platform should be adjusted to within 5mm.When semi-automatic cutting is carried out, the guide rail should be placed on the plane of the steel plate to be cut, and then the cutting machine should be placed lightly on the guide rail.Make one side of the cutting torch face the operator, choose the cutting nozzle according to the thickness of the steel plate, adjust the cutting straightness and cutting speed.
