GJ-101 submerged arc welding flux is a high-alkalinity sintered flux, specially designed for industrial welding applications to provide efficient and high-quality welding results. This fluoride-based flux has excellent slag removal performance, low impurity content (such as phosphorus and sulfur), and offers superior mechanical properties for carbon steel, low-alloy steel, and high-strength structural components. It is suitable for single-layer and multi-layer submerged arc welding (SAW), ensuring stable arc combustion, a beautiful weld appearance, and improving production efficiency in the manufacturing of pressure vessels, pipelines, and heavy machinery.

SJ-501 submerged arc welding flux is an active aluminum-titanium type acidic sintered flux, designed for high-efficiency welding, providing stable arc combustion and excellent weld quality. The basicity index of this flux is approximately 0.5-0.8, suitable for welding low-carbon steel and low-alloy high-strength structural steel, and performs particularly well in the manufacturing of LPG (liquefied petroleum gas) cylinders. It ensures a fast welding speed (up to more than 70m/h), easy slag removal, low spatter, and enhances the mechanical strength and corrosion resistance of the weld, applicable to industrial applications such as ships, boilers, and pressure vessels.

SJ101 is an advanced fluorine-alkaline type sintered flux, specifically designed for submerged arc welding processes, offering an excellent welding experience. Whether for single-layer or multi-layer welding, it ensures a stable arc, easy slag removal, and smooth weld formation. It is particularly suitable for carbon steel and low-alloy steel structural components, such as oil storage tanks and bridge components. The low-impurity formula reduces weld defects, enhances impact resistance and mechanical properties, and supports AC/DC current operation with uniform particle size (10-60 mesh). Unlike traditional fluxes, SJ101 has optimized alkalinity (approximately 1.8), reducing spatter and improving production efficiency. GJFlux is committed to high-quality welding materials, ensuring that SJ101 meets international standards (such as AWS), helping you reduce costs and enhance project reliability.
