During the welding operation, the operator needs to contact dangerous sources such as electricity, flammable gases, flammable and explosive materials, and also produces toxic, harmful gases and arc radiation during welding. This requires the operator to master the safety knowledge of welding, strictly Work in accordance with the welding safety operation regulations to avoid production accidents. Let ’s take a look with the editor of the Chengdu cold welding machine manufacturer:
(1) Safety technology to prevent electric shock
To prevent electric shock accidents, the welder should pay attention to the following points when performing welding operations:
① Before welding, check whether the welding machine is well grounded and whether the welding power cord and welding tongs are well insulated.
② When welding in a humid environment, you must stand on a place covered with insulation and wear insulated shoes.
③ During welding, it is strictly forbidden to touch live parts such as welding parts, workbenches and welding jaws with your hands.
④ When pulling down and closing the power switch, use one hand to prevent the current from forming a loop in the body in the event of an electric shock.
⑤ When the position of the electric welding machine needs to be moved, the power supply should be disconnected first; after the welding is completed, the electric welding machine switch should be turned off before the gate knife is pulled down.
(2) Safety technology for preventing fire and explosion
To prevent fires and explosions, welders should pay attention to the following points when performing welding operations:
① It is prohibited to store flammable and explosive materials, such as gasoline, kerosene, paint, wood chips, etc. within 10m of the welding site.
② When welding, care should be taken to prevent metal sparks from splashing and causing fire.
③ When welding workpieces such as pressure vessels and closed vessels, it is necessary to check in advance to release the pressure of the pressurized equipment and open all hole covers before welding.
④ When welding or cutting workpieces contaminated with grease or chemicals, they must be cleaned before proceeding.
⑤ When welding in a container, it is strictly forbidden to leave the welding or cutting tool in the container without permission, to prevent the mixed gas from burning and exploding.
⑥ When leaving the welding site, turn off the power supply and air supply, and extinguish the fire.
焊接 Welding operations on wooden boards are strictly prohibited.
(3) Prevention of arc injury and burns
① Wear protective clothing before welding to minimize skin exposure.
② During the welding process, a professional protective mask must be used. It is strictly forbidden to look directly at the welding arc with eyes.
