我单位参与承建的川气东送工程,西气东输二线平泰管道支干线工程,焊接方法为手工下向焊打底,自保护半自动药芯焊丝填充盖面,在甬沪宁战略石油管线等工程施工中也用此工艺由此看来,半自动焊在管线焊接中应用的越来越广泛。焊接材料、焊接设备是焊接技术的重要保证,因此也作介绍。同时也展望焊接技术的未来。 My unit involved in the construction of the Sichuan-East Gas Transmission Project, the West-East Gas Pipeline Pingtung Second Pipeline project, the welding method for the bottom of the hand welding, self-protection semi-automatic flux-cored wire filled cover, in the Shanghai-Nanjing strategic oil pipeline Engineering and other projects also use this process it seems, semi-automatic welding in the pipeline welding more widely used. Welding materials, welding equipment is an important guarantee of welding technology, it is also introduced. Also looking to the future of welding technology.
