The cutting methods of steel structure are:

1, Manual cutting

Is to use manual shears to cut the steel plate, but in the process of cutting, the steel plate is prone to crimping, and its cutting quality is poor, so it is not used much now.

2. Guillotine scissors

The blade length can reach 3 meters when cutting with a shearing machine. However, because the end of the shear machine is open, so in the shear process should pay attention to not cut out the steps.

3, Disc scissors

Continuous shearing can be done using a disc blade, although circular blanks can sometimes be cut by turning the tool.

4. Grinding wheel cutting

It uses high-speed grinding wheels made of fiber, resin or rubber to cut steel.

5, Laser cutting

Is to use the heat of the laser beam to cut the steel plate, it can be used to cut complex shapes of billets, and the maximum thickness of cutting up to 16 mm, but the price of equipment is relatively expensive.

6, Plasma arc cutting

It is to cut the steel plate with a thickness of 3-80 mm by passing the gas mixture through a high-frequency arc.

7, Carbon arc gas cutting

Carbon arc gas cutting through the arc generated between the carbon rod and the workpiece, and then the metal melting, so as to achieve the purpose of cutting.
