Welding wirecan be used with an inert gas shielded arc welding (TIG, MIG welding). Also be used for submerged arc welding. Stainless steel MIG welding can achieve highly efficient welding and welding automation, but also easy to implement and widely used in areas such as surfacing and sheet connected. MIG welding wire chemical composition and TIG welding wire, but some of the stainless steel variety, a SI with higher levels of MIG wire, such as corresponding with the ER308, ER309 wire ER308Si, ER309Si, etc., containing Si up to about 0.8%, reduces the surface tension of the metal droplet, the droplet particles thinner, easier to implement jet excessive, so that the arc becomes more stable. While improving the wettability of the metal droplet, so that the corrugated appearance of the weld bead and difficult to produce the lack of penetration, folder slag, porosity, lack of filling. Stainless Steel Electrode, its chemical composition and gas shielded arc stainless steel welding wire submerged arc welding, but should be equipped with no fierce silicon fluoride or manganese low-silicon high fluoride melting flux.
