The AWS ENi-Cl (Pure Nickel) electrode is specifically engineered for the welding of gray cast iron, ductile iron, and malleable iron. Unlike standard steel electrodes, the pure nickel core provides a soft, ductile weld deposit that accommodates the high carbon content of cast iron, preventing the brittle martensitic transition in the heat-affected zone (HAZ).
Modern engineering requires more than just "joining metal." Our ENi-Cl electrodes utilize a specialized graphitizing coating that enhances fluid control and slag detachability. This technical edge allows for "cold welding" techniques—reducing the need for extensive preheating and significantly lowering the risk of post-weld cracking.
As a premier China AWS ENi-Cl supplier, Shijiazhuang Tianqiao Welding Materials Co., Ltd integrates 15+ years of R&D to ensure that each batch meets ISO and AWS international benchmarks, serving sectors from automotive engine blocks to heavy maritime machinery.

Company Profile: Founded in 2007, we are located 30 kilometers southwest of Shijiazhuang. Our facility is strategically positioned for logistics, just 20 kilometers from the 107 national highway and near the Shixing and Jingzan highways. We possess a strong technical force and complete product testing equipment to maintain stable product quality.
Our organizational structure includes dedicated Production, Technical, R&D, QC & Laboratory, Sales, and Logistics departments, ensuring a seamless supply chain for our global partners.
Under our flagship brands "Yuanqiao" and "Changshan", we manufacture:
Our products are engineered for excellent performance, stable quality, elegant welding molding, and superior slag removal. They offer high resistance to rust, stomata, and cracking.
The future of AWS ENi-Cl lies in nano-structured flux coatings. We are currently researching the integration of rare-earth elements into the ENi-Cl coating to further refine grain structure and improve tensile strength by 15% without sacrificing machinability.
As Industry 4.0 penetrates the welding sector, our factory is optimizing wire feeding consistency for automated MIG/TIG processes. Our ENi-Cl variants are being redesigned for pulse-welding stability in robotic repair cells.
Our roadmap includes a "Low Fume" series. By modifying the silicate binders in our AWS ENi-Cl electrodes, we aim to reduce particulate emission by 30%, promoting a safer workspace for welders globally.
At Shijiazhuang Tianqiao, we don't just manufacture; we orchestrate a highly resilient supply chain. Our "Factory 4.0" approach includes:
Cast iron components in marine environments suffer from chloride-induced corrosion. Our ENi-Cl electrodes provide a metallurgical bond that resists galvanic corrosion, making them ideal for pump housings and valve bodies.
From bridge supports to urban piping, we provide solutions that comply with international structural codes. Our products are widely used in metallurgy, petroleum chemical industry, boilers, and pressure vessels.
We ensure 100% compliance with ASTM, AWS, and JIS standards. Our R&D team works closely with global clients to adjust chemistry for specific regional iron grades, ensuring localized success.
For international buyers, the choice of an AWS ENi-Cl supplier hinges on more than price. It's about Technical Reliability, Batch Consistency, and Post-Sales Support.
Our products are 100% exported, reaching the US, Europe, South America, Australia, Africa, Middle East, and Southeast Asia. We understand the specific documentation and packaging requirements for diverse customs jurisdictions.
Under the spirit of "Supreme Quality, Honesty, Win-Win Cooperation," we aim to create brilliance with every distributor. We seek long-term, stable relationships based on mutual benefit.
A: Yes, but with caution. For multi-pass welding, it is essential to keep the interpass temperature low. We recommend short beads (25-50mm) and peening immediately after welding to relieve stress.
A: ENi-Cl is pure nickel (95%+), making the weld softer and more machinable. ENiFe-Cl contains roughly 45% iron and is used for high-strength ductile irons where cost-effectiveness and higher tensile strength are required.
A: We offer the agility of a specialized manufacturer with the reach of a global exporter. Our quality-to-price ratio is industry-leading due to our optimized "China Factory 4.0" operations.
