Description

technical field [0001] The invention relates to a welding method of a hollow tungsten pole coaxial MIG / MAG composite welding device. Background technique [0002] As far as arc welding technology is concerned, the traditional non-melting tungsten argon arc (TIG welding) side-axis filler wire welding technology has always been the preferred technology for high-quality welding in some key fields because of its unique process stability. Many key areas that promote the rapid development of the national economy have played an important role; compared with non-melting electrode tungsten argon arc welding, traditional melting electrode gas shielded welding (MIG / MAG welding) can also achieve filling while using arc heat to melt the matrix The synchronous melting of materials meets the needs of material filling in the welding process, and even realizes the regulation of the metallurgical process of the weld. This method has technical advantages such as high welding efficiency and goo...
