Welders in operation needs to have good professional protective means, such as gloves, masks, shoes, apron and pajamas glasses, etc.
So don't worry there are dangerous.
As long as the operation is very safe in accordance with the procedures.
1, the welding operation, must be dressed the necessary labor protection, electric welder welding shall be used for welding makeup mask, safety glasses should be worn when slag removal, gas welding (
Workers should wear protective glasses.
Second, it is forbidden to pressure container, pipeline welding in the welding place 5 m within it is strictly prohibited to store flammable and explosive articles, a flammable medium trap, welding shall be with alkaline water or steam thoroughly clean the residual medium, button hole or hand hole is correct after the operation, Fang Kexuan welding.
Three, before welding repairing acetylene generator, must rinse off with clear water and fire test, is correct after Fang Kexuan welding.
Fourth, mobile near acetylene generator, it is forbidden to contact fire from the welding spot keeping more than 10 meters.
Five, acetylene generator should set safety device of explosion proof and prevent tempering, often check generator and tempering to prevent water injection, shoulds not be too high or too low, instrumentation and security should be regular inspection, to ensure that sensitive and reliable.
Six, acetylene generator should set safety device of explosion proof and prevent tempering, often check generator and tempering to prevent water injection, shoulds not be too high or too low, instrumentation and security should be regular inspection, to ensure that sensitive and reliable.
Seven, tempering to prevent freezing, can use hot water or steam heating, ban on roast acetylene generator parts and attached tools cannot use unique copper production, in case of copper and explode.
2, oxygen tanks and pressure reducer is strictly prohibited contact with grease, on the pressure reducer, should first open the oxygen cylinder valves will bottle dirt dye quality blow off, oxygen acetylene cylinder high and low pressure table is nimble and reliable.
Second, the oxygen acetylene cylinders should be properly handling storage, avoid collision and vibration shall not be in the sun exposure and to avoid heat source.
After three, pressure reducer mount, should first open a cylinder, again open pressure reducer, cylinders should be shut down after work, then close the pressure reducer, operation welder should flanking pressure reducer.
Four, are not allowed to put all the oxygen in the oxygen bomb, should retain 0.
The pressure of 2 mpa.
Five, oxygen hose and acetylene hose shall not be in use or substitute, pipe joint fight air leakage.
3, welding torch use should prevent excessive heat in a, when a tempering should be quickly shut down when the oxygen valve, then close the acetylene gas valve.
Second, acetylene tube burst fire, should quickly folded hose in the former period will be on fire.
Oxygen tubes is on fire, should be quickly shut oxygen cylinder valve.
Out the flame with folding tube method is prohibited.
Three, electric welding machine must have a reliable grounding.
Fourth, the welding line should have good insulation, broken skin leakage should be repaired in time.
Welders is a very good technology, but to be a good welder really need to study hard.
