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.

SJ301 submerged arc welding flux is a high-performance agglomerated calcium-silicate flux designed for efficient welding of low-carbon and low-alloy steels. With a neutral basicity index of 1.0, it delivers stable arc performance, effortless slag detachment, and superior weld bead aesthetics, making it ideal for high-speed applications in industries like pipeline construction, bridge building, and machinery fabrication. Certified under AWS A5.17 F6A0-EL8 and F7A2-EM12K standards, this flux minimizes porosity and ensures strong mechanical properties, such as tensile strength up to 670 MPa when paired with EM12K wire. As a reliable choice from Chinese manufacturers, SJ301 enhances productivity by supporting AC/DC currents and multi-layer welding without interface defects. Perfect for structural projects requiring durability and cost-efficiency.
