Safety and Protection Technology

SMAW operation, you must pay attention to safety and protection, safety and protection technology to prevent electric shock, arc radiation, fire, explosion and toxic gas and smoke poisoning.

prevent electric shock

The SMAW grid voltage and welder output voltage as well as mobile lighting voltage and so there is a danger. Therefore, to prevent electric shock measures taken. Or access to zero. The good welding cables and welding tongs insulation, if damaged, must be promptly repaired. The SMAW, wear insulated shoes wearing welding gloves. Welding boilers, pressure vessels, piping, narrow wet ditch, there must be insulated pad, and someone outside the guardianship. The use of portable lights, the voltage does not exceed the safe voltage 36V, high-altitude operations does not exceed 12V. Aerial work near high-voltage lines 5m or from the low-pressure line 2.5m within job must be power outages, and warning signs hung gates, Let guardianship. Someone in case of an electric shock, quickly cut off the power, and timely rescue.

prevent arc radiation

The strong arc welding arc and ultraviolet damage to the eyes and skin. SMAW, you must use a mask with a piece of arc welding goggles, wearing overalls and wearing welding gloves. Multiplayer welding operation, pay attention to avoid mutual influence, should set the arc shield or take other measures to avoid cross-arc radiation.
Isolated from Mars. More than six strong winds, did not take effective security measures can not be open-air welding operations and aerial work, welding near the job site should fire facilities. Welding Materials work is completed should wind up, and clean up the site in a timely manner, the complete elimination of the fire.

prevent fires

In welding operations the ignition source lOm within the organic dust, wood, sawdust, cotton yarn, cotton yarn, straw, hay, oil, gasoline, paint and other flammable items should be thoroughly cleared below the altitude operations and welding Mars reach. Flammable substances, if any, can not be evacuated, such as wood, insulation not removed combustible materials, reliable safety measures should be taken, such as water jet wet covering wet sacks, asbestos cloth, and so on.

prevent explosion

Explosive materials in the Welding Wire Chinaoperation point lOm less, shall, in the explosive mixture of gas depots, oil room, acetylene plant, spray booth indoor, non-welding operations. Without special measures, can not be welded to the inner pressure of the pressure vessel and piping. Carrying loaded containers of inflammable and explosive materials before welding To costumes articles exhausted, and water, water vapor or nitrogen replacement, clean test analysis of the concentration of the gas medium: explosimeter and other instruments; welding operations To open the flap, operating personnel have to hide away from the container orifice.

prevent toxic gases and smoke poisoning

SMAW will produce soluble fluoride, hydrogen fluoride, manganese, nitrogen oxides and other toxic gases and dust, will lead to a fluorine poisoning, manganese poisoning, welded pneumoconiosis, etc., especially alkaline electrode in the container, the internal pipe welding worse. Therefore, according to the specific circumstances to take a comprehensive ventilation, local exhaust ventilation, small welding smoke unit ventilation exhaust soot measures.
