Jinan Gujin Welding Materials Co., Ltd. (formerly Laiwu Gujin Welding Materials Co., Ltd.) is an enterprise established through investment from the municipal government to develop and produce automatic submerged arc welding flux. It currently has a large number of submerged arc welding flux, sintered flux,welding flux,sj101 flux, sj414 flux, roller surfacing flux, steel structure flux, melting flux, etc. The company produces 10000 tons of sintered welding and 6000 tons of melted welding flux annually, with an annual output value of 46 million yuan. The company has a large production capacity, a wide variety of products, and excellent quality.
The product has been widely used in various industries such as ships, boilers, oil/gas pipelines, bridges, and mechanical construction, among which the SJ501 flux is exported nearly 3000 tons annually. Especially the roller repair welding fluxes SJ102, SJ414, and SJ103 have been widely praised by customers.
Since 2003, solid metal welding materials have been exported in bulk to over 10 regions including Russia, Thailand, Malaysia, Iran, India, and Italy.
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 SJ......
Read MoreSend InquiryGJ-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.
