GR2 Titanium Welding Wire

• Material characteristics:The titanium content is ≥ 99.5%, and the impurity content is strictly controlled (Fe ≤ 0.20%, O ≤ 0.18%, N ≤ 0.03%), in accordance with ASTM B348 and GB/T 3623 standards. The surface of the welding wire is pickled or polished to remove the oxide film and ensure that there is no impurity contamination during the welding process.
• Welding performance:Tensile strength ≥ 270MPa, elongation ≥ 27%, and welding joint strength can reach over 90% of the base metal. Support low current rapid welding (such as TIG welding current 50-80A), reduce heat input, and lower deformation risk.
• Process adaptability:The diameter of the welding wire is between 0.8mm and 6.0mm, and can be customized with coiled or straight wires. During welding, argon gas with a purity of ≥ 99.99% should be used for protection, and both the front and back should be covered with a protective shield to ensure that the silver white of the weld is not oxidized. Good compatibility with GR1/GR2 titanium plates and TA1/TA2 pure titanium materials, suitable for corrosion-resistant scenarios such as seawater desalination equipment and chemical containers.

• Chemical equipment: Welding of titanium reaction vessels and heat exchangers, with an annual corrosion rate of less than 0.02mm in highly corrosive environments such as hydrochloric acid and nitric acid.
• Ocean engineering: Welding of pressure resistant shells for seawater desalination devices and deep-sea detectors to maintain stability in a 5000 meter deep sea environment.
• Food processing: Welding of dairy production line pipelines in compliance with FDA food contact standards.

Technical Parameter

• Chemical composition: Ti ≥ 99.5%, Al ≤ 0.10%, V ≤ 0.10%, in accordance with ASTM B348 and GB/T 3623 standards;
• Typical specifications: diameter of 0.8mm to 6.0mm, straight wire length of 500-1000mm, coil wire weight of 5-20kg;
• Surface condition: Acid wash (Ra ≤ 3.2 μ m) or glossy surface (Ra ≤ 0.8 μ m).

Quality Assurance

• Adopting vacuum melting+cold drawing process, the entire process passes ultrasonic testing and third-party mechanical performance testing. The surface of the welding wire is strictly cleaned (acetone degreasing+acid washing), and the packaging is vacuum sealed to prevent moisture. Support fast delivery in small batches.
