SJ101 Fluorine-alkaline type sintered flux

Core Characteristics of SJ101 Flux

SJ101 fluorine-alkaline sintered flux stands out due to its unique chemical composition: the balance between fluoride and alkaline oxides provides high alkalinity (1.8-2.0), ensuring excellent toughness and crack resistance of the weld metal. Unlike common fluxes on the market, SJ101 emphasizes low hydrogen content, reducing the risk of hydrogen-induced cracks, and is suitable for welding high-strength steel.

• Welding performance: Stable arc, minimizing spatter; easy slag removal design, saving cleaning time.

• Weld quality: Smooth bead-like appearance, excellent forming; improving the impact toughness and elongation of the weld.

• Compatibility: Compatible with various welding wires (such as THM-43B), supporting single-wire, multi-wire, and strip electrode submerged arc welding.

Technical specifications

Application Scenarios and Cases

SJ101 is particularly suitable for the welding of oil storage tanks in the petrochemical industry, as well as bridge and pipeline structures in the construction field. For example: in high-strength steel projects, SJ101 has helped users reduce the welding defect rate by 20% and achieve seamless connections through multi-layer welding. Compared with competing products, its performance in low-temperature environments is more stable, avoiding the common problem of slag shell adhesion.

Usage Guidelines and Safety Tips

Preheat the flux to 350°C to remove moisture; control the current between 400-600A to ensure optimal penetration. For safety: wear protective equipment and avoid inhaling dust. GJFlux provides free technical support, including optimization of welding parameters.

SJ101 flux, with its low-impurity formula and compatibility with multi-layer welding, ensures defect-free and impact-resistant welds. It is suitable for AC/DC currents, with a particle size of 10-60 mesh. Contact GJFlux for customized welding recommendations and technical data sheets.
