Everyone's safety affects the well-being and happiness of the home. Therefore, as a stainless steel sheet metal fabrication plant operator, everyone needs to be especially safe. In order to better your loved ones and everyone around you who is concerned about you, then, what are the safety precautions for the production and processing of sheet metal for safety tool cabinets and the actual operation of welding? I explain to you from a sheet metal processing plant business in Zhejiang Province. Avoid electric shock
In welding work, there are two kinds of safety accidents: one is immediate electric shock accident, that is, touching the transmission line; the second is indirect electric shock, that is, touching all normal operation when not battery charging objects, because the insulation is destroyed or common fault and is called energized objects.
The specific way in which an immediate electric shock occurs during the whole welding process is that:When removing and changing welding wire and welding parts, some part of the sheet metal frame or body comes into contact with energised parts such as welding tongs and welding wire, while the rest of the foot or body is not well insulated between the road and the metal component. For example, it is very easy to get an electric shock when welding on vessels, pipes, in rainy and cold locations, or when people sweat a lot on their man-ladders. When hands or parts of the body touch exposed and energised terminals, terminals, cable wires and other electric shocks; welding around high voltage lines can lead to penetration charging because of the close proximity.
Indirect electrocution during the entire welding process is mainly caused by leakage from welding machines and equipment, which includes: leakage due to reduced insulation characteristics caused by load application and short circuit faults in the internal structure of the machine and equipment; leakage from solenoid coils due to insulation damage caused by precipitation and moisture in the body; and leakage due to partial destruction of the insulation of wires and cables.
Avoid leakage of countermeasures mainly contains: strict implementation of operating procedures actual operation; welding the whole process should be accurate with protective equipment; welding machine and equipment casing reliable grounding device, because when the casing leakage, because the earth wire resistance is small, the vast majority of electric flow is not easy according to the body, but rather according to the wire joints to produce control circuit, to avoid straight climbing ladder electrocution accident; selection of suitable cable and wire, strengthen the safety of the great Check.
