Titanium tube welding is a TiG welding process that effectively protects the welding area using inert gases. Due to the unique physical and chemical properties of titanium material, its welding process differs greatly from other metals. Titanium pipes have high strength, good plasticity, toughness, and corrosion resistance, making them increasingly widely used in aerospace, shipbuilding, and chemical industries. To better utilize titanium pipes, it is necessary to master their weldability.
The titanium tube manufacturer stated that the following points must be ensured during welding
1. The metal in the welding area is not contaminated by active gases N, 0, H, and harmful impurity elements C, Fe, Mn, etc. above 250 ℃.
2. Coarse grain structure cannot be formed.
3. It is not allowed to generate significant welding residual stress and deformation. Therefore, the welding process must follow the predetermined construction sequence, strictly follow the process quality management standards, and implement quality control throughout the entire process. This ensures that all factors such as human, machine, material, and method are in a good controlled state, thereby ensuring the welding quality of titanium pipes within a reasonable construction period.
