The small diameter thin-walled TA2 titanium tubes are used in a technical renovation project. In order to ensure the performance of the product, the automatic GTAW welding process is adopted by analyzing the weldability of TA2 titanium tubes. The process qualification tests such as appearance inspection, nondestructive testing, mechanical properties and metallographic examination are carried out. The test results show that the welding joint with good performance can be obtained by reasonable welding procedure parameters and strict gas protection measures. The welding procedure and related measures can be used as a reference for manufacture and installation of titanium pipes.
