TA2
Complies with: GB/T3623-2007 TA2
Explanation: TA2 is a commercial pure titanium welding wire with lower impurity content compared to TA1 welding wire. It has good mechanical properties and excellent welding process performance.
Application: Used for welding titanium based alloys, mainly in projects such as seawater and saltwater heat exchangers, condensers, and paper bleaching systems.

Requirements for radiographic testing of weld metal: Level I
Precautions and operating points:
1. The welding area must be thoroughly cleaned of surface impurities such as oil stains, rust, and moisture.
2. To prevent oxidation of the weld surface due to high temperature during welding, a tail cover must be added to enhance the protective effect.
