Automatic gas pipeline welding technology(Gas Shielded Welding Wire) and the use of welded wire molten metal between the arc as the heat source to melt the wire and steel pipe, welded in the welding time to the regional transportation protective gas to isolate the harmful effects of air through the completion of a continuous CO2 welding wire manufacturers . Since MIG welding welding zone of protection is simple, easy to observe the welding area, high efficiency welding process is relatively simple, easy to control, easy to achieve all-position welding.
Zhengzhou - Yima Gas Pipeline Project (East) pipe made of 16Mn, diameter 426mm, wire for the H08Mn2SiA, wire diameter of 1.0mm. The process by welding, welding performance is good.
The process can be realized simultaneously for all position multiple heads, backing weld welding from the inside of the tube can also be outside of the tube welding. General regulation of welding parameters on the console or control panel, the main process parameters: welding current, arc current, wire feed speed, each welding head speed, swing frequency, swing swing width and delay time. Should be noted that, due to the different welding parameters for each weld, the weld pipe welding parameters should be based on specifications and site conditions, only after passing through the welding test used in production.
Automatic pipe welding gas welding technology for its high quality and welding speed, etc., has been popular in foreign countries, while in the country is in the promotion stage. Our self-developed automatic gas shielded arc welding equipment has been in Zhengzhou - Yima Gas Pipeline Project in the applications. Automatic gas welding is under the protection of the long-distance pipeline to the welding technology under development.
