Gas welding is the use of combustible gas and oxygen mixed combustion to form the high temperature flame, gas welding with combustible gases are acetylene, methane, liquefied petroleum gas, the most commonly used in production is acetylene. The application of gas welding has a long history, but the current application of gas welding has been narrowed with the development of various arc welding and contact welding. Gas welding is suitable for a variety of metal materials, equipment is simple, low cost, flexible welding gun, suitable for all types of welding work, the application is more common.
Gas welding operation, the most important tool is the welding gun.
Carbon gouging rods gouging torch is most wide use, the role of the torch is combustible gas and oxygen in a certain proportion of uniform mixing, at a certain speed to discharge from the nozzle, form a certain rate, a certain composition, suitable for welding requirements and stable combustion of the flame.
