Flux-cored wire is also called powder-cored wire and tubular wire. It is divided into two categories: gas-entrained and non-gas-protected. The surface of the flux-cored wire is the same as that of the solid wire, and is made of materials such as low-carbon steel or low-alloy steel with good plasticity. The manufacturing method is to first roll the steel strip into a U-shaped section shape, then fill the solder powder prepared according to the dosage into the U-shaped steel strip, roll it tightly with a rolling mill, and finally make it into different specifications by drawing. cored wire.

Flux cored wire is divided into seamed and seamless flux cored wire according to production characteristics. The finished wire of seamless flux-cored wire can be copper-plated, and the moisture-proof performance during storage and the conductivity during welding are better than those of seamed flux-cored wire.

Flux cored wire has different classification methods according to different situations.

According to the protection situation, it can be divided into four types: gas protection (CO2, Ar-rich mixed gas) and self-protection, submerged arc and open arc.

According to the wire diameter, it can be divided into thin diameter (below 2.0mm) and thick diameter (above 2.0mm).

According to the wire section, it can be divided into simple section and complex section.

According to the power supply used, it can be divided into AC steep drop characteristic power supply and DC flat characteristic power supply.

According to the filling material, it can be divided into slag-forming flux cored wire (titanium oxide type, titanium calcium type, calcium fluoride type) and metal powder cored flux cored wire.

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, etc. (general diameter 1.2mm-1.6mm)

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

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