The global structural, automotive, energy, and marine fabrication sectors demand unprecedented mechanical reliability, deposit efficiency, and chemical precision. OEM contract manufacturing in joining technologies has evolved beyond basic electrode extrusion into micro-alloy engineering and smart flux technology.
Achieving exact tensile toughness and low-temperature Charpy V-notch impact performance requires rigorous control of deoxidizers (Al, Ti, Zr) and micro-alloying additives within both solid wire cores and electrode flux coatings.
Modern automated GMAW and FCAW manufacturing processes mandate consistent wire drawability, uniform copper plating, precise helix/cast dimensions, and spatter-free arc stability to minimize industrial downtime.
From specialized flux binders like tailored potassium silicate to precise alloy powders for cellulosic E6010, E6011, and rutile E6013 electrodes, OEM partners require bespoke chemical formulations matched to local standards.
Shijiazhuang Tianqiao Welding Materials Co., Ltd was founded in 2007 located in 30 kilometers in the southwest of Shijiazhuang. Our factory traffic is very convenient just 20 kilometers to the west of 107 national highway, also near to the Shixing and Jingzan highway. We have strong technical force, complete product testing equipment so that we can keep stable product quality. Our company is composed of production department, technical department, R&D department, QC & Laboratory, Sale department, Logistic department.
Under our flagship brands, we operate multi-line automated production systems capable of producing low carbon steel, low alloy steel, heat-resistant steels, low temperature steel, stainless steel, cast iron, and hard surfacing welding electrodes, as well as high-purity submerged arc fluxes and specialized chemical precursors.
Different industrial sectors demand specialized deposit mechanical properties, crack resistance, and thermal endurance. Our engineered products are tailored for critical applications globally.

As enterprise procurement shifts toward zero-defect manufacturing and environmental compliance, our R&D department drives progress in four core engineering vectors:
Self-shielded flux-cored wires like E71T-GS and E71T-11 eliminate the need for external shielding gas cylinders, making them indispensable for outdoor construction, structural repair, and wind-exposed sites. Innovations in core flux formulations focus on aluminum-denitriding agents that react with atmospheric nitrogen to form stable nitrides, preventing porosity while maintaining high tensile ductility.
Our SJ101 Submerged Arc Welding Flux represents a fluoride-basic agglomerated chemistry engineered for high-yield steel structural fabrication. Featuring balanced silicate-to-fluoride ratios, SJ101 offers exceptional resistance to moisture pickup, easy slag detachability, and optimal detachability in narrow gap joints, resulting in ultra-clean weld deposits with low diffusible hydrogen.
Electrode extrusion quality depends entirely on binder rheology. Our customized Potassium Silicate binder solutions provide tailored viscosity, controlled drying rates, and smooth extrusion properties for carbon steel and stainless steel electrodes (E6013, E71T series, E308L). Combined with precise E6013 welding powder mixes, OEMs can achieve arc stability and spatter-free transfer.
Joining high-alloy and non-ferrous metals demands precise chemistry control. Our stainless range (E308L-16, E316L-16, E309L-16) utilizes extra-low carbon content (<0.04%) to eliminate intergranular carbide precipitation. For non-ferrous applications, CuZn40Fe1Sn1 brass rods and ER4043 aluminum wires deliver superior wetting action and joint strength.
Our products are 100% exported and sold worldwide, primarily across the US, Europe, South America, Australia, Africa, the Middle East, and Southeast Asia. B2B global enterprise buyers choose us because our products combine top performance with competitive factory-direct pricing.
As automation and robotics redefine structural welding, our engineering strategy focuses on three advanced technological frontiers:
Implementation of continuous high-speed optical vision systems on our extrusion lines to detect micro-cracks, surface concentricity variations, and flux coating thickness anomalies in real-time before baking.
R&D investments into low-hexavalent chromium fume formulations for stainless steel electrodes (E308L, E316L), protecting operator health while meeting stringent international environmental regulations.
Precision layer winding technology for GMAW wires like ER70S-G and ER4043, ensuring zero friction wire feeding in automated robotic welding arms under high duty cycles.
Answers to common technical queries from welding engineers, distributors, and corporate procurement directors.
