Matters needing attention in the actual cutting of Security screen meshs

Security screen meshs are often cut and welded according to needs in actual daily use. The following are the matters needing attention for Security screen mesh cutting in detail.

When the Security screen mesh is cutting thick weldments and cutting at a high speed, there will be a drag on the cutting surface, that is, the lower half of the cutting gun has not completely cut through when the cutting gun runs to the end. Therefore, when cutting to the end of the cutting line, the cutting speed should be appropriately reduced to enable full cutting. Security screen mesh cutting of thin plate weldments often uses punching and cutting methods in test plates. When punching holes in the test plate, the pressurized water will cause the end of the nozzle to wear away and splash of water mist. If the weldment is thin, the holes will be penetrated quickly, which can avoid the above problems; when the welding thickness is large, the kickback phenomenon is more serious, and the time required for punching is quite long, so it is not suitable to use a test plate for punching. From the way. Matters needing attention when cutting high-pressure water jet welding Security screen meshs.

Precautions when cutting high-pressure water jets for welding Security screen meshs.

① After one cutting operation is completed and the high-pressure water jet cutting machine is stopped, the operator should check and confirm the following items to make the next cutting work smoothly.

② In order to prevent the operator from being injured due to improper setting of the cutting torch or high-pressure water backlash and water jet scattering when punching, the cutting area should be properly shielded around the high-pressure water jet from the operator.

③ For the water mist formed by the pressurized water jet, if the factory building is not provided with a general ventilation and exhaust device, at least the cutting area should be equipped with a gastric ventilation and exhaust device.

④ In order to prevent the high-pressure water jet from recoiling during the cutting process, the structure of the cutting table should be properly designed, and a nozzle device can be installed at the head.

⑤ When manually transferring the material to be cut to the cutting table or removing parts after cutting, in order to avoid the high-pressure water jetting out and injuring workers, the residual pressure of high-pressure water must be released in advance.

⑥ The high-pressure water jet will cause great harm to the operator. Therefore, the Security screen mesh must release the residual pressure of the high-pressure water before replacing the nozzle.
