Effect of Temperature Field on Formation of Friction Stir Welding Joints of Ti–6Al–4V Titanium Alloy
Abstract: In order to investigate the formation mechanism of tunnel defect produced near the bottom of stir zone (SZ) in friction stir welding joint of Ti–6Al–4V titanium alloy, the temperature distribution during welding process was analyzed by numerical simulation and experiment. Results show that macrostructure morphology of SZ in cross section presents “bowl” shape owing to the characteristic of temperature distribution. Obvious temperature gradient appears along the thickness direction of joint. Decreasing rotational velocity reduces peak temperature and temperature gradient, which is beneficial to eliminate tunnel defect.
