Solid Core Stainless Steel Welding Wire

Solid core stainless steel welding wire can be inert gas welding (TIG, MIG welding). It can also be used for submerged arc welding. MIG welding of stainless steel can not only achieve high efficiency welding, but also easy to realize welding automation, widely used in surfacing and thin plate welding and other fields. MIG welding wire chemical composition and TIG wire, but for some stainless steel varieties, there is a higher SI CONTENT of MIG wire, such as ER308,ER309 corresponding ER308Si,ER309Si, etc., due to the SI up to 0.8% or so, reduce the surface tension of the metal droplets, the droplets particles become fine, It is easier to achieve spray overshoot, making the arc more stable. At the same time, it can improve the wettability of the droplet metal, so that the weld bead ripple is beautiful, and it is not easy to produce incomplete welding, slag, porosity and other missing filling. Solid core stainless steel welding wire for submerged arc welding has the same chemical composition as gas shielded stainless steel welding wire, but it should be used with low silicon and high fluorine flux without fierce silicon and fluorine or manganese.
