In the high-stakes world of heavy-duty construction and pressure vessel manufacturing, the choice of welding consumables is the difference between structural longevity and catastrophic failure. The AWS E7018, known as the "low-hydrogen" electrode, stands as the industry standard for high-quality, high-strength welds. As a leading OEM 7018 Welding Rod Manufacturer, we integrate chemical precision with industrial-scale production to meet the rigorous demands of global engineering.
The "70" in 7018 signifies a minimum tensile strength of 70,000 psi, while the "1" indicates its versatility for all welding positions. The iron powder in the coating ensures high deposition rates, while the low-hydrogen nature prevents cold cracking—a critical factor when working with thick plates or high-carbon steels.
Our proprietary coating formulation ensures that the 7018 rods exhibit extreme resistance to moisture absorption, maintaining low-diffusible hydrogen levels even in humid shipyard environments.
Enhanced with specialized ionizing agents, our 7018 electrodes provide a smooth, stable arc with minimal spatter, reducing post-weld cleanup and increasing operator efficiency.
Designed for macro-infrastructure, our rods offer superior Charpy V-Notch impact properties at -30°C (-20°F), making them ideal for Arctic pipelines and offshore rigs.
Leveraging China's world-class supply chain and our specialized facility in Shijiazhuang, we offer an unparalleled balance of quality, scale, and technical customization.
Located near China's steel manufacturing hubs, we source high-purity core wires directly, reducing logistical overhead and ensuring consistent batch-to-batch chemical composition.
Our in-house QC & Laboratory (as mentioned in our profile) utilizes spectral analysis and X-ray testing to ensure every batch of 7018 electrodes meets AWS A5.1 standards.
We provide full-spectrum branding services, from customized vacuum packaging to specialized rod markings, allowing global distributors to scale their own brands with ease.
Founded in 2007, Shijiazhuang Tianqiao Welding Materials Co., Ltd is located 30 kilometers southwest of Shijiazhuang. Our facility is strategically positioned just 20 kilometers from the 107 national highway, near the Shixing and Jingzan highways, ensuring a highly convenient logistics network for global shipping.
We possess strong technical force and complete product testing equipment. Our structured organization—comprising production, technical R&D, QC, Sales, and Logistics departments—guarantees that every "Yuanqiao" or "Changshan" brand product maintains stable, high-tier quality.
Our 7018 rods are the backbone of high-rise buildings and bridges. The high ductility and strength allow structures to withstand seismic activities and high-stress loads.
Used extensively in hull construction. Our electrodes are resistant to the corrosive effects of marine environments and provide crack-free joints in thick-walled vessels.
From pressure vessels to transmission pipelines, our 7018 rods ensure the integrity of the "Gold Standard" weld required for high-pressure containment.
Modern procurement directors are moving beyond "price-per-kg" metrics. Today’s trend focuses on Total Cost of Welding (TCW). Choosing a high-quality OEM 7018 rod reduces costs through:
Minimal slag and porosity mean fewer failed X-ray tests.
Iron powder in our 7018 allows for faster welding speeds.
China's industrial resilience ensures consistent supply despite global volatility.
Our manufacturing processes are optimizing energy use for greener production.
