On May 6, 2026, batches of ERTi-2 titanium welding wire, having undergone rigorous quality inspection, were being packed and shipped from the Baoji Titanium Valley Industrial Cluster. In recent days, multiple batches of welding wire products have been successively shipped to domestic chemical equipment manufacturing bases and overseas end-users, covering various specifications such as coiled wire and straight wire. This fully responds to the urgent needs of key fields such as aerospace equipment welding, marine engineering pipeline systems, and chemical pressure vessels, marking a new stage in the mass production and delivery capabilities of this series of titanium welding wires.
I. High-end welding material, precisely addressing complex working conditions
As a welding benchmark in the field of industrial pure titanium, ERTi-2 titanium welding wire is mainly used for welding Grade 2 industrial pure titanium, with a titanium content exceeding 99%. Impurities such as carbon, oxygen, hydrogen, nitrogen, and iron are strictly and precisely controlled, ensuring superior welding performance under low-impurity conditions. The product strictly adheres to advanced domestic and international standards such as AWS A5.16 ERTi-2 and GB/T 30562 STi 0120. The entire process, from raw materials to finished products, is traceable, and all batches are accompanied by complete Material Testing Certificates (MTCs), covering key indicators such as chemical composition and mechanical properties, ensuring the safety and stable performance of each batch.
In terms of performance, this product exhibits stable and excellent welding processes. The deposited metal possesses both excellent strength and ductility, achieving a perfect balance between strength and toughness. The weld formation is aesthetically pleasing, and the quality is consistently controllable. Regarding key technical indicators, the typical chemical composition of ERTi-2 titanium welding wire includes carbon ≤0.03%, oxygen 0.08~0.16%, hydrogen ≤0.008%, nitrogen ≤0.015%, and iron ≤0.12%. The typical tensile strength of the deposited metal reaches 345 MPa, the yield strength is 275 MPa, and the elongation is 20%. With its superior performance, this welding wire significantly reduces weld defect rates and repair costs, effectively improving the long-term service reliability of welded structures. It is particularly suitable for applications with extremely high reliability and service life requirements, such as marine environments, chemical industries, and medical technologies.
II. Diverse Applications, Precisely Adaptable Welding Processes
Regarding welding processes, ERTi-2 titanium welding wire is recommended for use with tungsten inert gas (TIG) welding. The optimal welding current range is 50A to 300A, adaptable to the welding requirements of base materials of varying thicknesses. It is important to note that titanium begins to absorb hydrogen above 250°C, oxygen above 400°C, and nitrogen above 600°C. The penetration of impurities will significantly reduce the mechanical properties of titanium. Therefore, strict control of interpass temperature and the use of gas protection measures (such as protective shields) are essential during welding to ensure high-quality weld joints and fully utilize the superior performance of the titanium welding wire.
Based on its excellent comprehensive performance, the application scope of ERTi-2 titanium welding wire continues to expand: in the chemical industry, it is widely used for welding heat exchangers, pressure vessels, and various pipeline systems; in the marine engineering field, thanks to its excellent resistance to seawater corrosion, it serves as an ideal welding material for seawater heat exchangers and pipeline systems, leading to continuous growth in demand in shipbuilding and offshore equipment.
III. Leveraging the "Titanium Valley" Ecosystem, Both Production Capacity and Delivery Improve
In recent years, China's titanium industry production capacity has accounted for 60% to 70% of the global total. Under the framework of the 15th Five-Year Plan, the self-sufficiency and controllability of the industrial chain for key strategic materials such as titanium have been continuously improved. As a basic consumable in high-end manufacturing, our company's titanium and titanium alloy welding wires have been exported to more than 10 countries and regions. With the continuous expansion of market demand along the "Belt and Road," the pace of exporting titanium welding wire products has significantly accelerated.
Against this macro-industrial background, this successful shipment further verifies the full-chain supply capability of ERTi-2 titanium welding wire, from raw material supply to finished product processing. Leveraging the industrial cluster advantages of Baoji, known as "China's Titanium Valley," the company maintains integrated control over the entire process, from titanium smelting and precision drawing to surface treatment and quality inspection. With advanced production equipment and mature processes, the company has developed a comprehensive welding wire product line covering various specifications, including φ0.8mm, φ1.0mm, φ1.2mm, φ1.6mm, φ2.0mm, φ2.4mm, and φ3.2mm, fully meeting the refined material selection needs of different welding conditions.
IV. Continuous Deepening of Development, Striving to Become a Global Premium Titanium Welding Material Service Provider
With the continuous growth in global demand for high-performance materials, the application scope of titanium and its alloys is constantly expanding, directly driving a significant increase in the demand for titanium welding wire. Especially in fields such as aero-engine structural component manufacturing, deep-sea engineering equipment, and high-end chemical plants, the irreplaceable role of titanium welding wire is becoming increasingly prominent.
In the future, our company will continue to focus on the research, development, and production of high-end titanium welding wire products. Supported by stable and reliable quality, timely and efficient delivery, and customized technical services, we will accelerate our global market expansion, contributing to the technological innovation and application expansion of titanium welding materials in cutting-edge fields such as intelligent manufacturing, deep-sea engineering, and green energy. We aim to provide reliable one-stop titanium welding solutions for the global high-end manufacturing industry.
