In the global landscape of heavy manufacturing, Flux Powder serves as the fundamental catalyst for structural integrity. As a specialized OEM Flux Powder supplier, Shijiazhuang Tianqiao Welding Materials Co., Ltd. understands that welding flux is not merely a consumable; it is a complex chemical agent designed to shield the weld pool from atmospheric contamination, stabilize the electric arc, and introduce essential alloying elements into the weld metal. In today’s era of high-speed automation and Submerged Arc Welding (SAW), the demand for high-performance sintered and agglomerated fluxes has reached a critical peak, driven by infrastructure projects in the US, Europe, and Southeast Asia.
The global welding consumables market is undergoing a seismic shift. There is an increasing "Search Intent" for solutions that offer Information Gain regarding "Hydrogen-Controlled Welding" and "Low-Basicity Sintered Flux." Our role as a factory is to bridge the gap between traditional metallurgy and the future of industrial robotics, providing OEM services that allow for custom chemical compositions tailored to specific environmental conditions—be it the sub-zero temperatures of arctic pipeline construction or the corrosive environments of offshore wind farms.
With 100% of our production dedicated to international markets, we navigate the complexities of global logistics. From Shijiazhuang to the ports of Europe and the Americas, we ensure a seamless supply of flux powder for large-scale maritime and energy projects.
Our dedicated R&D department focuses on the chemistry of slag formation. By optimizing the "Basicity Index" of our SJ101 and SJ302 series, we provide superior slag detachability and a smooth weld bead profile that reduces post-weld processing time.
Submerged arc welding flux is the backbone of high-rise buildings and bridges. Our factory produces high-purity powder that minimizes stomata and cracks, ensuring that the deposited metal exceeds standard mechanics performance requirements.
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. This structural depth ensures that every batch of OEM Flux Powder meets rigorous internal standards before being dispatched to our global partners.
High-resistance to corrosion and high-pressure vessel integrity. Our fluxes support the demanding requirements of boiler and pressure vessel manufacturing.
Automated SAW processes in shipyards require consistent flux grain size and chemical uniformity. Our SJ-series provides deep penetration and excellent surface finish.
From surfacing electrodes for heavy gear repair to carbon steel electrodes for structural builds, we cover the entire spectrum of national economic fields.
"Our products include kinds of welding electrodes with the brand of 'Yuanqiao', 'Changshan', such as low carbon steel, low alloy steel, and various mixed welding powder."
The transition from fused flux to agglomerated sintered flux (like our SJ101) represents a leap in metallurgical control. Sintering at lower temperatures allows for the inclusion of deoxidizers and alloying elements that would otherwise be lost in the high-heat fusion process.
Future iterations of our OEM Flux Powder focus on reducing the carbon footprint and fluoride emissions during welding. This is crucial for compliance with tightening European and North American environmental regulations.
Integration of AI-driven quality control in our factory ensures that each grain of powder meets the exact mesh size required for high-speed automated welding, preventing clogs in flux recovery systems.
Our products are one hundred percent exported and have sold worldwide, mainly to US, Europe, South America, Australia, Africa, Middle East, and Southeast Asia. We understand that "Local Support" means more than just delivery; it means providing the technical data sheets (TDS) and material safety data sheets (MSDS) required by local regulatory bodies in each region.
Compliant with AWS A5.17 and A5.23 standards for submerged arc welding, ensuring acceptance by US engineering firms.
Focus on environmental safety and consistent mechanical properties for infrastructure and boiler construction.
Providing cost-effective, high-performance solutions for rapidly developing regions in Africa and Southeast Asia.
A: SJ101 is a fluoride-basic type sintered flux. It provides excellent mechanical properties, particularly low-temperature impact toughness, making it ideal for offshore structures and pressure vessels.
A: Flux powder is hygroscopic. It must be stored in a dry environment. If exposed to moisture, it should be re-baked at 300-350°C for 2 hours to prevent hydrogen cracking in the weld.
A: Yes, as a factory with a dedicated R&D department, we can adjust the basicity index and alloying elements to match specific welding wire chemistry and parent metal requirements.
A: Our SJ302 and SJ101 series are engineered for "self-lifting" slag removal, significantly reducing labor costs in high-volume production environments.
