Paper Title:
Residual Stress State of TIG Remelted Zone in the Weld Toe after Chilling Treatment
  Abstract

Using the software named ABAQUS, the residual stress distributions of welding toes for the Q345C butt joints and T-joints are simulated, respectively. The simulations are performed in three cases which are as-welded, TIG remelting after welding, and chilling treatment for the welding toes after TIG remelting at different temperatures, respectively. The stress measurement is performed for these areas using the blind-hole method. The results of measurement and numerical simulation indicate that the residual stresses for the surface of the welding toes can be transformed into the biaxial compression stress when the TIG remelting zone temperature of welding toes is above 450 °C,which is availible for the improvement of fatigue strength of welded joints.
