316 stainless steel flux-cored wire

316 stainless steel flux-cored wire  

The basic working principle of flux-cored wire gas-shielded arc welding is the same as that of ordinary MIG welding. It is based on fluxable cored wire as one electrode (usually connected with positive pole, namely DC reverse connection) and base metal as the other pole. Usually using pure CO2 or CO2 + Ar gas as a protective gas. The main difference from the conventional MIG welding is that the wire is internally filled with a flux mixture. Welding, in the arc heat under the molten flux material, wire metal, parent metal and shielding gas metallurgical role between each other, while forming a thin layer of liquid slag coated droplets and cover the molten pool, the The molten metal forms a further layer of protection.

Flux-cored wire, also known as tubular wire, can be easily designed by different kinds of alloy composition and proportion of wear-resisting, high-strength, heat-resisting, corrosion-resisting and low-temperature resistant. Because of its alloy composition can be flexible and convenient adjustment, so many varieties of flux-cored wire is solid wire can not be smelted and rolled. While the flux-cored wire due to the characteristics of product structure, welding process performance and welding efficiency compared to solid wire, hand electrode more advantages.

Common gas-shielded flux-cored wires are: AWS A5.29 / 5.28 E71T1-C (M), E81T1-K2, E81T1-NI1, E91T1-K2, E101-K3, E111T1-K3, E80C-G, E90C-G, E110C-G and so on (the general diameter 1.2mm-1.6mm).

Common self-shielded flux-cored wire: general diameter: 1.6mm-3.2mm

Common submerged arc welding flux-cored wire: AWS A5.23 F71A, F8A4, F9A4, F11-A8, etc. (general diameter: 2.4mm-4.0mm)
