Welding flux SJ102

China Welding flux SJ102 Factory Directly Supply. GUJIN® is Welding flux SJ102 manufacturer and supplier in China. GJ.SJ-102 is a fluorine alkali type Agglomerated submerged arc welding flux, which is a slightly yellow spherical particle with a particle size of 10-60 mesh and an alkalinity of about 2.6. Its loose to loose ratio is about 1.0, and the flux has low S and P content. The weld formation is beautiful, the surface is smooth, and the neutral of the flux does not transition to silicon manganese.Submerged Arc Flux SJ-102 is mainly used to replace small diameter HJ260 and HJ107 surface welding rollers, solving the problem of difficult high-temperature slag removal.Equipped with the same welding wire, it saves about 25% compared to melted flux. Submerged Arc Flux SJ-102 can also be matched with corresponding welding wires for narrow gap welding of low-carbon steel and some low alloy steels.

Usage:

Submerged Arc Flux SJ-102 Suitable for multi pass welding with carbon steel, low alloy steel, austenitic stainless steel and martensite stainless steel welding wires. This flux is suitable for direct current reverse welding, and its welded joints have excellent mechanical properties and low-temperature impact toughness. It is matched with corresponding surfacing welding wires for surfacing, and the surfacing layer has good comprehensive resistance to high-temperature oxidation. Compared with HJ260, this submerged arc welding flux has shorter slag performance and lower chemical activity, better high-temperature slag removal performance, beautiful weld formation, small alloy element combustion loss, and superior performance in all aspects to HJ260.

Cautions:

1. Submerged Arc Flux SJ-102 must be baked at 300-350 ℃ for 2 hours before use. 

2. Before welding, impurities such as rust, oil stains, and moisture should be removed from the welded parts.
