In the world of industrial fabrication, the AWS A5.1 E7018 welding electrode stands as a cornerstone of reliability. Known as a "low-hydrogen, iron powder" electrode, the 7018 is specifically designed to provide high-quality welds in applications where cracking must be avoided and mechanical properties are paramount. As a leading OEM 7018 Welding Electrodes Supplier & Factory, Shijiazhuang Tianqiao Welding Materials Co., Ltd. provides the technical depth and manufacturing precision required to meet international standards (AWS, ISO, GB).
The "70" in 7018 signifies a minimum tensile strength of 70,000 psi, while the "1" indicates its suitability for all welding positions. The "8" refers to the low-hydrogen potassium coating, which includes iron powder for increased deposition rates. This combination makes it the preferred choice for bridges, offshore platforms, pressure vessels, and heavy machinery.
China hosts the world's most complete welding material supply chain. From raw rutile sand and iron powder to specialized flux coatings, our proximity to high-grade steel mills ensures cost-efficiency without compromising metallurgical purity.
Modern Chinese factories like Tianqiao utilize automated extrusion lines and precision-controlled drying ovens. This ensures the 7018's low-hydrogen coating maintains its integrity, resulting in a stable arc and easy slag removal.
We provide full-spectrum OEM services, including custom branding, specialized packaging for moisture resistance (vacuum packs), and adjustments to flux chemistry to meet specific project Charpy V-Notch (CVN) requirements.
Founded in 2007, Shijiazhuang Tianqiao Welding Materials Co., Ltd. is located 30 kilometers southwest of Shijiazhuang. Our facility is strategically positioned for logistics, just 20 kilometers from the 107 national highway and near major Shixing and Jingzan expressways.
Our infrastructure includes a Production Department, Technical Department, R&D Department, QC & Laboratory, Sale Department, and Logistic Department. This vertically integrated structure allows us to maintain stable quality and offer "Yuanqiao" and "Changshan" brands alongside our extensive OEM services.
Our Product Range: Beyond 7018, we produce low carbon steel, low alloy steel, heat-resistant steels, stainless steel, cast iron, and hard surfacing electrodes. We also manufacture sintered flux and various welding wires.
The demand for 7018 electrodes is shifting toward more specialized "Information Gain" applications. As an OEM 7018 Welding Electrodes Supplier, we tailor our solutions for the following sectors:
Used in high-rise buildings and seismic-resistant structures. Our 7018 electrodes provide the ductility required to absorb energy during tectonic shifts.
Perfect for pipelines and refinery vessels. The low diffusible hydrogen (H4 or H8 levels) prevents cold cracking in high-strength steels.
Corrosion resistance and superior mechanical properties in extreme cold. Our electrodes are tested for low-temperature toughness down to -30°C.
The welding industry is evolving. We are integrating AI-driven QC systems in our factory to monitor flux consistency and coating concentricity in real-time. This "Smart Manufacturing" approach reduces waste and ensures that every batch of OEM 7018 electrodes meets the exact specifications of our global partners.
Key trends we are currently addressing include:
Our products are widely used in various national economic fields, such as machinery, metallurgy, petroleum chemical industry, boiler, pressure vessel, the ships, the buildings, and more. Our products are sold to all over the country and well received by vast users.
Global Reach: Our products are one hundred percent exported and have sold worldwide, mainly to the US, Europe, South America, Australia, Africa, Middle East, and Southeast Asia. Our success is built on "Supreme Quality, Honesty, and Win-Win Cooperation."
