Engineered for stability, precision, and global industrial standards.
The "Gold Standard" of high-tensile structural welding consumables.
The E7018 is a high-quality carbon steel electrode with iron powder and low-hydrogen potassium coating. Its unique flux composition ensures a tensile strength of 70,000 psi, making it indispensable for critical joints that must withstand high stress and low temperatures.
Modern infrastructure projects in the US, Europe, and the Middle East are shifting toward "H4R" moisture-resistant coatings. As an industry leader, our E7018 rods provide extended exposure limits, reducing the need for constant re-baking in high-humidity environments.
While E7018 is traditionally a manual process (SMAW), current trends focus on the consistency of the rod core. Our manufacturing process ensures uniform coating thickness, which is vital for professional welders seeking predictable arc performance and easy slag detachment.
Founded in 2007, we represent the pinnacle of Chinese welding material manufacturing. Located just 30km from Shijiazhuang, our strategic location near the 107 national highway and major expressways ensures unparalleled logistic efficiency.
How we leverage technology to ensure 100% export reliability.
By integrating vertically—from raw material sourcing (like our own Rutile sand production) to the finished electrode—we mitigate global market volatility. This ensures our clients receive stable pricing and consistent lead times even during global shipping crises.
Our "Factory 4.0" initiative involves automated flux mixing and high-speed extrusion lines. This technology reduces human error, ensuring that every batch of E7018 meets the exact chemical composition required for AWS certification.
Every shipment is backed by a Mill Test Certificate (MTC). Our QC Laboratory utilizes spectrometers and mechanical testing rigs to verify tensile strength, yield points, and elongation before the product leaves the facility.
Our products, branded under "Yuanqiao" and "Changshan," are versatile powerhouses in the industrial world. From low carbon steel to heat-resistant and stainless steel, our range covers:
We are proud to say our electrodes are 100% exported, reaching the US, Europe, South America, Australia, Africa, the Middle East, and Southeast Asia.
Direct answers from our senior technical engineers.
E7018 flux contains minimal hydrogen-bearing compounds. This prevents "hydrogen-induced cracking," which is common in high-strength steel welds. It must be stored in a rod oven to maintain this property.
The iron powder increases the deposition rate, allowing welders to fill joints faster while maintaining a smooth, stable arc and excellent bead appearance.
To ensure E-E-A-T compliant results, we recommend storing rods in a heated oven at 250°F to 300°F (120°C-150°C) after opening the original vacuum-sealed packaging.
No, E7018 is designed for "all-position" welding except vertical-down. It excels in flat, horizontal, and vertical-up positions due to its fast-freezing slag.
Unlike trading companies, we own the full production cycle. This ensures that the "Information Gain" we provide isn't just marketing—it's backed by laboratory data and direct control over raw material purity.
Yes, we provide extensive OEM services, including custom branding for mild steel and stainless steel electrodes, tailored to specific regional certifications.
In the global industrial landscape, the reliability of a weld is the difference between project success and catastrophic failure. The China Welding Rods E7018 manufactured by Tianqiao are engineered with a specific focus on the Heat Affected Zone (HAZ). Our chemical formulation optimizes the manganese-to-silicon ratio, promoting a fine-grained weld structure that offers superior notch toughness at sub-zero temperatures.
As we transition into the era of Global Infrastructure 2.0, the demand for resilient supply chains has never been higher. Procurement managers now prioritize "Supply Chain Resilience" over the lowest possible unit cost. Tianqiao addresses this by providing "Total Quality Transparency." Every pallet of our E7018 electrodes is traceable back to the raw batch of steel wire and flux minerals used.
Furthermore, our commitment to "Supreme Quality, Honesty, and Win-Win Cooperation" isn't just a culture—it's a business model. By reducing slag interference and spatter levels, we help contractors reduce post-weld cleaning time by up to 20%, providing a significant "Efficiency Gain" in large-scale industrial builds.
