The global infrastructure development and advanced manufacturing sectors are driving unprecedented demand for high-reliability welding materials. At the heart of this metallurgical demand lies the welding electrode flux material. The flux system is not merely a cover for the core wire; it is a highly engineered chemical reactor that operates under extreme arc temperatures (exceeding 3,000°C to 5,000°C). Globally, industrial stakeholders are looking for customized OEM formulations that cater to specific environmental and mechanical criteria—such as low-temperature toughness in offshore oil rigs, high-temperature creep resistance in chemical pressure vessels, and high deposition rates in heavy structural civil engineering.
In terms of commercial status, the global welding consumables market is valued at billions of dollars, with flux and powder components representing a massive share. Rapid industrialization across developing economies, combined with the structural retrofitting of bridges, ships, and energy transmission networks in developed regions, has positioned top-tier OEM factories as critical supply chain partners. Modern welding operations cannot afford failures, making the selection of high-grade raw ingredients (like rutile, calcium carbonate, fluorite, silica, and custom-sintered silicate binders) a foundational requirement for modern heavy industry.
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 the spirit of "Supreme Quality, Honesty, Win-Win Cooperation", we are willing to achieve common development and create brilliance with all of our customers. We are looking forward to establishing a mutual-benefit, long-term, and stable relationship with customers and distributors all over the world. We believe we can achieve a splendid future by our efforts together.
Our products include kinds of welding electrodes with the brand of "Yuanqiao", "Changshan", such as low carbon steel, low alloy steel, heat-resistant steels, low temperature steel, stainless steel, cast iron, hard surfacing welding electrodes. All kinds of sintered flux and various kinds of welding wire and various mixed welding powder.
Our products have excellent performance, stable quality, elegant welding molding, good slag removal, good ability to resist rust, stomata and crack, and good and stable deposited metal mechanics performance. Every batch of mixed welding powder and flux-cored fill powder undergoes extensive spectrometer validation to ensure alloy transfer percentages meet strict mechanical engineering certifications.
High-rise steel columns and large span bridges depend on robust structural joints. Our AWS E6013 and AWS E6011 mild steel electrodes provide stable penetration and excellent slag detachability, ensuring speed and safety on-site under variable ambient temperatures.
Working under thermal stress and corrosive chemical environments requires high alloy stability. Our stainless steel AWS E308L-16, E309-16, and E316L-16 series prevent chromium depletion and provide excellent localized corrosion resistance.
For high-volume shipyard fabrication and wind tower assembly, Submerged Arc Welding (SAW) using SJ101 flux paired with precise wire options ensures extreme deposition efficiency with minimal hydrogen embrittlement risks.
Product Application and Reach: The products are widely used in various national economic fields, such as machinery, metallurgy, petroleum chemical industry, boiler, pressure vessel, the ships, the buildings, bridges, and so on. The products are sold to all over the country, and well received by the vast users. Our products are 100% exported and have sold worldwide, mainly to the US, Europe, South America, Australia, Africa, Middle East, Southeast Asia, and beyond. Our products meet customers' warm welcome due to the excellent quality, outstanding performance, and competitive pricing structures.
The design of a high-performance welding electrode flux is a multi-disciplinary chemistry task. As a leading OEM factory, we formulate and customize flux coatings using specialized mineral systems to meet particular shielding and arc stability criteria. Each class of flux serves a distinct operational purpose:
| Flux System Type | Primary Mineral Components | Arc Performance Characteristics | Ideal Application Scenario |
|---|---|---|---|
| Acid System (Rutile-based) | TiO₂, SiO₂, Al₂O₃, Silicates | Soft arc transfer, minimal spatter, excellent cosmetic bead appearance, easily detachable slag. | General fabrication, sheet metal, cosmetic cap passes on structural frames. |
| Basic System (Low-Hydrogen) | CaCO₃, CaF₂ (Fluorite), MgCO₃ | Short, forceful arc, high structural purity, extremely low diffusible hydrogen (HDB < 4ml/100g). | High tensile steel joins, pressure vessels, maritime hulls, sub-zero temperature operations. |
| Cellulosic System | Organic Cellulose, TiO₂, Iron Powder | Deep penetration arc, high gas volume shield (H₂ & CO), fast-freezing slag system. | Cross-country pipeline vertical-down root passes, high wind outdoor welding environments. |
| Sintered Fluoride-Basic (SAW Flux) | Al₂O₃-MnO-SiO₂-CaF₂ | Excellent current carrying capacity, stable voltage control under heavy current, high slag viscosity. | Large diameter pipe production, heavy structural girders, wind turbine tower structural seams. |
As advanced automation and environmental standards reshape global industrial sectors, the technological development of welding consumables must evolve. Shijiazhuang Tianqiao Welding Materials Co., Ltd is constantly pioneering innovative initiatives across our product portfolios to address the demands of next-generation manufacturing:
