Cracking in the welds of titanium 2 pipelines
Thread Content
Cracks in the out-of-track welds appeared in the pipeline welds of Titanium 2? Aqueous sodium chloride solution, around 90°C
Cracking in the welds of titanium 2 pipelines may be caused by stress concentration during welding or improper material selection. High temperatures and sodium chloride aqueous solutions can accelerate corrosion, thereby increasing the brittleness of the weld area and leading to cracks. It is recommended to examine the welding process, use welding materials more suitable for high-temperature and corrosive environments, and carry out appropriate post-treatment to reduce stress. .
Cracks appeared in the TA2 weld; this is likely due to factors such as inadequate cleaning of the welding material, the root gap of the base metal, and the weld itself during welding, impure shielding gas used during welding, and defects in the welding process (failure to provide proper argon protection around the weld).
