What to weld titanium tubes with

March 19, 2024

The welding of titanium tubes can be done by a number of different welding methods, including but not limited to:

1, tungsten argon arc welding (GTAW): suitable for butt, angle and lap welding of titanium and Titanium Alloy plates, tubes and shaped parts with a thickness of 0.5~10mm. This method has high weld quality and small deformation, but need argon protection to avoid weld oxidation or nitration pollution.

2, electron beam welding (EBW): for the thickness of 0.1 ~ 150mm of titanium and titanium alloy plates, tubes and shaped parts of the butt, angle and lap welding. It can be carried out in a vacuum to avoid gas contamination, has a larger weld depth to width ratio and large deformation, and high efficiency.

3、Laser Welding (LW): It is suitable for butt, fillet and lap welding of titanium and titanium alloy plates, tubes and shaped parts with a thickness of 0.1~10mm. It can be carried out in the atmosphere, only before and after the need to blow argon protection, with a large weld depth to width ratio and small deformation, fast speed, automation or robotization can be achieved.

4, plasma arc welding (PAW): for thickness of 0.5 ~ 15mm titanium and titanium alloy plates, tubes and shaped pieces of butt, angle and lap welding. It is carried out in the atmosphere, only before and after blowing argon protection, with a large weld depth and width ratio and small deformation, high efficiency.

5、Brazing(BW)：Applicable to butt, angle and lap welding of titanium and titanium alloy plates, tubes and shaped parts with a thickness of 0.1~3mm.

6, melting pole argon arc welding (MIG welding): for the welding of titanium in the thickness of the DC reverse connection.

7, resistance welding: due to the titanium resistivity, thermal conductivity is small, resistance welding is more suitable.
