The company has a complete production line and can provide high-quality CORE ROD, MIG WIRE, TIG WIRE, FLUX WIRE and COATED ELECTRODES and other series of products.The company always adheres to the business philosophy of "quality first, customer first", has established a strict quality management system, and is equipped with world-leading testing equipment to ensure stable and reliable product quality. The products are widely used in petrochemical, electric power, shipbuilding, bridges, machinery manufacturing and other fields, selling well in domestic and foreign markets, and are well received by customers.

As the core component of efficient welding solutions, submerged arc welding wire is widely used in the global industrial manufacturing field due to its excellent welding performance and mechanical properties. Our submerged arc welding wire adopts advanced production technology to control the chemical composition and wire precision, and forms a perfect welding system with special flux to ensure stable arc, high-quality welds and efficient deposition in various heavy welding scenarios, providing reliable welding guarantee for key industries such as pressure vessels, heavy machinery, and shipbuilding. 

• Stable arc: Unique wire formula ensures continuous arc stability during welding, reducing spatter and porosity defects
• Superior slag removal: After welding, the slag is completely stripped, which greatly reduces the cost of the slag removal process and improves the efficiency of surface treatment
• Beautiful weld formation: Excellent molten pool fluidity, smooth and uniform welds, and reduced subsequent grinding workload
• High deposition efficiency: Compared with manual arc welding, the welding speed is increased by 3-5 times, significantly shortening the production cycle

• Strictly control the content of key elements such as C, Mn, and Si to ensure perfect matching with various fluxes
• Ultra-low S and P impurity content (≤0.03%), effectively improving the purity and crack resistance of the weld
• The copper plating layer is uniform and dense, ensuring excellent conductivity and wire feeding smoothness, and adapting to the needs of automated welding

 

Technical characteristics

 

The scientific ratio of submerged arc welding wire and flux is the key to determining the quality of the weld:
• Two-way control mechanism: Accurately control the chemical composition of the weld metal through the complementary composition of the welding wire and flux
• Process flexibility: supports multiple combination schemes - a single welding wire matches multiple sintering fluxes, or multiple welding wires match a smelting flux
• Performance customization: optimize the mechanical properties of the weld through the flux-wire combination according to the parent material composition and welding requirements

• Wide applicable current range: supports DC reverse connection and AC welding
• Strong plate thickness compatibility: stable performance from medium thickness to large structural parts welding
• Position adaptability: mainly suitable for flat welding and horizontal welding positions, meeting the needs of most industrial welding scenarios

• Before welding, make sure the surface of the base material is free of oil, rust and moisture
• The flux needs to be dried at 250-350℃ for 1-2 hours before use
• Adjust the dry extension length according to the welding position (usually 25-40mm)
• Use DC reverse polarity to obtain better penetration and stability

Full-process quality control: 16 quality control procedures from raw material screening to finished product inspection
Performance testing: Each batch of products undergoes mechanical performance tests such as tensile, impact, and bending
