TIG Titanium Wire

TIG Titanium Wire | High precision welding consumables, suitable for high-end welding needs of titanium materials
TIG Titanium Wire is a welding consumable designed specifically for the TIG (tungsten inert gas welding) process of titanium and titanium alloys. With low impurities and high welding stability as its core advantages, it fully complies with international welding standards such as AWS A5.16 and ASTM B863, and is widely used in global aerospace, medical equipment, marine engineering, and other fields. As a key consumable for titanium welding, it can accurately match the composition and properties of titanium and titanium alloy base materials, ensuring that the weld strength and corrosion resistance are consistent with the base material, and solving the industry pain points of easy oxidation and porosity in titanium welding.

The size parameters of TIG titanium welding wire are deeply adapted to different welding scenarios, with a conventional diameter range of 0.8mm-4.0mm, supporting 0.6mm ultra-fine specifications (for welding thin-walled titanium parts) and 5.0mm coarse specifications (for welding thick walled titanium structures); The diameter tolerance is strictly controlled within ± 0.02mm (fine specification) to ± 0.05mm (coarse specification) to ensure uniform wire feeding and avoid poor weld formation caused by diameter deviation; We offer two types of packaging for length: straight bars (500mm/1000mm) and disc packaging (10kg/20kg per disc). Straight bars are suitable for manual TIG welding, while disc packaging is suitable for automated TIG welding production lines; The surface has undergone special degreasing and brightening treatment, with no oil stains or oxide scales. No additional cleaning is required during welding, and it can be used directly. The entire series of products meet the requirements of EU CE and US AWS certification.

The grade design of TIG titanium welding wire is precisely matched with the titanium base material. The mainstream grades include ER-GR1, ER-GR2, and ER-GR5, covering the welding requirements of pure titanium and titanium alloys. ER-GR1 welding wire has a titanium purity of ≥ 99.5% and extremely low impurity content (iron ≤ 0.25%, oxygen ≤ 0.18%), suitable for welding GR1 pure titanium base material. It is mainly used in scenarios with high purity requirements such as food equipment and medical non implantable devices; The strength of ER-GR2 welding wire is slightly higher than that of ER-GR1, suitable for GR2 pure titanium base material, and suitable for welding industrial grade titanium containers and ocean exploration equipment; ER-GR5 (ER-Ti-6Al-4V) welding wire contains 6% aluminum and 4% vanadium, which is consistent with the composition of GR5 titanium alloy base material. The tensile strength of the weld can reach over 860MPa, and it is suitable for welding aerospace structural components and high-end medical implant devices (such as artificial joints).

The core advantage of TIG titanium welding wire focuses on improving the welding performance of titanium materials. Its low impurity content can reduce defects such as porosity and cracks during the welding process, and the weld qualification rate can reach over 99%; The corrosion resistance of the welded metal after welding is equivalent to that of the base metal, and there is no intergranular corrosion in seawater and acidic media, making it suitable for titanium structures in the marine and chemical industries; The welding wire melts uniformly, has good formability, and can achieve precision welding of thin-walled titanium parts (thickness ≤ 1mm), as well as meet the strength requirements of multi-layer and multi pass welding of thick walled titanium parts (thickness ≥ 20mm), without the need for complex heat treatment after welding, simplifying the production process.
