Gas shielded welding wire is divided into two types: solid wire and flux cored wire. In China, solid-core welding wire is mainly used at present, but flux-cored wire is rapidly spreading and has a broad application prospect.
Special welding wire for gas shielded arc welding. According to different manufacturing methods, it is also divided into two types: solid wire and flux cored wire. In China, solid-core welding wire is mainly used at present, but flux-cored wire is rapidly spreading and has a broad application prospect. In Japan, the amount of solid wire is still greater than that of flux-cored wire, but the type of flux-cored wire is more, used for carbon steel, low-alloy high-strength steel, low-temperature steel, heat-resistant steel and stainless steel. Various kinds of welding wires, and various flux-cored welding wires suitable for surfacing. According to the welding method and the shielding gas, it can be divided into TIG welding wire, MIG welding wire and mag welding wire. The TIG welding wire is matched with pure Ar as a shielding gas, and the wire composition is close to the weld composition. MIG welding wire is matched with Ar+2%O2 or Ar+5% CO2 shielding gas, mainly used for welding high alloy steel such as stainless steel. MAG welding wire can be combined with Ar plus 5% or more of CO2 or Ar plus 2% or more of O2 shielding gas, or 100% CO2 as shielding gas. The latter type of shielding gas is low in cost and is widely used for welding carbon steel, low alloy steel and stainless steel, and can also be used for surfacing welding.
