The Best WANJING Brand Stainless Steel Welding Wire From China
Stainless steel solid core welding wire can be used for inert gas shielded welding (TIG, MIG welding). Can also be used for submerged arc welding. MIG welding of stainless steel can not only achieve high-efficiency welding, but also easily realize welding automation. It is widely used in fields such as cladding and thin plate welding. The chemical composition of the welding wire used for MIG welding is the same as that of TIG welding wire. However, for some stainless steel varieties, there is also a MIG welding wire with a higher SI content, such as ER308Si, ER309Si, etc. corresponding to ER308 and ER309 welding wire. Since the Si content is as high as about 0.8%, The surface tension of the droplet metal is reduced, the droplet particles become finer, it is easier to achieve over-spraying, and the arc becomes more stable. At the same time, it can also improve the wettability of the molten metal, making the weld bead ripples beautiful and less prone to defects such as incomplete penetration, slag inclusions, and pores. The chemical composition of solid stainless steel welding wire used for submerged arc welding is the same as that of stainless steel welding wire for gas shielded welding, but it should be equipped with a non-manganese, medium silicon and fluorine or a manganese-free, low silicon and high fluorine type smelting flux.

With stainless steel flux-cored welding wire, stainless steel can be welded just as easily and efficiently as carbon steel and low-alloy steel. Stainless Steel Round Wires The main application of stainless steel flux-cored welding wire is MAG welding. A MAG welding machine has the following characteristics: 1) Compared with manual welding, deposition speed is 2-4 times faster, and deposition efficiency is 90% (stainless steel electrodes only contribute 55%). There is a large range of adaptability to current and voltage, setting welding conditions is relatively simple, and semi-automated and automated welding can be carried out easily. In addition to good slag removal, the weld bead surface is glossy. Additionally, there is little spatter, excellent arc stability, and qualified X-rays.
