Our company primarily uses TIG welding for titanium material processing. During welding, titanium is covered by shielding gas, preventing exposure to air, which helps to avoid oxidation and eliminates spatter. Welding inside assembly pipes is very challenging, and during material preparation, each part is carefully angled and manufactured with attention to dimensional accuracy. Additionally, by using a welded structure instead of bolts, we contribute to airtightness and weight reduction in tanks and other applications. [Features] - Titanium during welding is covered by shielding gas, preventing exposure to air and avoiding oxidation. - No spatter is generated. - The process of covering the welding area with shielding gas according to the shape and content of the weld requires skilled techniques. - By using a welded structure instead of bolts, we contribute to airtightness and weight reduction in tanks and other applications. *For more details, please refer to the PDF document or feel free to contact us.

Titanium 64 alloy (Ti6AL-4V) has excellent properties, with a tensile strength more than 1.7 times that of pure titanium and a yield strength more than 3.8 times greater, making it a highly versatile representative variety among titanium alloys. ELI material (ASTM F136) is a typical variety of medical titanium, known for its excellent low-temperature toughness. This 64 titanium alloy has specially low levels of oxygen, nitrogen, hydrogen, and iron. Please feel free to contact us for anything from mass production to test pieces and samples.
