Established in 2007, Shijiazhuang Tianqiao Welding Materials Co., Ltd. has emerged as a titan in the welding consumable industry. Located strategically 30 kilometers southwest of Shijiazhuang, our 20,000-square-meter facility enjoys unparalleled logistics access via the 107 National Highway and the Shixing/Jingzan highways.
Our commitment to EEAT principles is reflected in our robust organizational structure, comprising specialized Production, Technical, R&D, QC & Laboratory, Sales, and Logistics departments. With a vision to provide more than just products, we deliver engineering-grade solutions for the world's most demanding carbon steel and alloy joining requirements.
The AWS E7018 Welding Electrode represents the pinnacle of manual metal arc welding (MMAW) for structural steel. As a leading manufacturer, Tianqiao has optimized the iron-powder low-hydrogen potassium coating to ensure that our 7018 series provides superior mechanical properties and crack resistance.
Our formulation ensures diffusible hydrogen levels below 8ml/100g, significantly reducing the risk of cold cracking in high-tensile thick plates.
Maintains exceptional Charpy V-Notch impact values even at sub-zero temperatures (-30°C to -45°C), critical for arctic or offshore applications.
Engineered for a stable arc, minimal spatter, and easy slag detachability, allowing for high-efficiency welding in all positions.
The welding industry is undergoing a paradigm shift toward Automation and Sustainability. Tianqiao's R&D roadmap focuses on "Green Welding" consumables—reducing hexavalent chromium in fumes and developing moisture-resistant coatings that eliminate the need for extensive on-site re-baking. We are also integrating AI-driven quality control in our extrusion lines to ensure every batch of Yuanqiao and Changshan electrodes meets a 0% defect tolerance.
At Tianqiao, "Made in China" has evolved into "Intelligent Manufacturing in China." Our factory 4.0 initiative leverages real-time monitoring of flux composition and wire drawing tension. This Information Gain ensures that our global partners receive consistent metallurgical performance, regardless of order volume.
Our supply chain resilience is anchored in our vertical integration—from raw material sourcing to final vacuum-sealed packaging. This allows us to maintain competitive pricing while mitigating the volatility of global logistics.
Our 7018 and stainless steel series (E308L, E316) are engineered for high-pressure vessels and heat exchangers where thermal fatigue resistance is paramount.
Providing the backbone for global skyscrapers and bridges with electrodes that offer high deposition rates and flawless X-ray quality welds.
Corrosion-resistant flux formulations designed to withstand harsh maritime environments and rigorous ABS/DNV standards.
Tianqiao understands that global trade requires localized trust. Our products meet AWS, ISO, CE, and GB standards. We provide full MTC (Material Test Certificates) with every shipment, ensuring total traceability. For our partners in the US, Europe, and Southeast Asia, we offer localized technical support to assist in WPS (Welding Procedure Specification) qualification.
E7018 has a special coating that contains very little moisture. This prevents hydrogen from entering the weld pool, which is the primary cause of delayed cracking in high-strength steels. Proper storage and re-baking are essential to maintain this property.
While both maintain Tianqiao's high-quality standards, the brands are tailored for different market segments and specific application nuances, ranging from general structural use to specialized industrial fabrication.
Yes, the "8" in 7018 indicates that it is a low-hydrogen potassium coating designed for use with AC or DC+ (Direct Current Electrode Positive) polarity, providing a smooth, stable arc on both.
We utilize an in-house laboratory to perform chemical analysis of raw wires and coating minerals before production. Post-production, we conduct mechanical tests including tensile, yield, and impact testing for every batch.
Yes, we have a specialized OEM department that helps global distributors develop their own branded welding consumables, including custom packaging and specialized chemical formulations.
