The welding of titanium tubes can be performed using a variety of different welding methods, including but not limited to:
1, tungsten argon arc welding (GTAW) : suitable for the thickness of 0.5~10mm titanium and titanium alloy plates, pipes and special-shaped parts of the butt, corner and lap welding. This method has high weld quality and less deformation, but requires argon protection to avoid weld oxidation or nitrification contamination.
2, electron beam welding (EBW) : suitable for the thickness of 0.1~150mm titanium and titanium alloy plate, pipe and shaped parts of the butt, Angle and lap welding. It can be carried out in vacuum, avoid gas pollution, has a large weld depth to width ratio and large deformation, and high efficiency.
3, laser welding (LW) : suitable for the thickness of 0.1~10mm titanium and titanium alloy plates, pipes and special-shaped parts of the butt, corner and lap welding. It can be carried out in the atmosphere, only need to blow argon gas protection, with a large weld depth to width ratio and small deformation, fast speed, can be automated or robotized operation.
4, plasma arc welding (PAW) : suitable for the thickness of 0.5~15mm titanium and titanium alloy plates, pipes and special-shaped parts of the butt, Angle and lap welding. It is carried out in the atmosphere, only need to blow argon gas protection, with a large weld depth to width ratio and small deformation, high efficiency.
5, brazing (BW) : suitable for the thickness of 0.1~3mm titanium and titanium alloy plates, pipes and special-shaped parts of the butt, Angle and lap welding.
6, MIG welding: suitable for the welding of medium thickness titanium, using DC reverse connection.
7, resistance welding: Because titanium resistivity is large, small thermal conductivity, resistance welding is more suitable.
