Paper Title:
Residual Stress Correlation in Two Different Mitigation Techniques Using FEA
  Abstract

Many techniques were developed to control residual stress and distortion during welding process to minimizes their magnitude in the affected area. Due to complicity to find qualitative analysis for welding residual stress and distortion in real experiment work, the numerical simulation of welding process give a good solution to helpful the process and evaluated extensive analysis. In the present paper two different residual stress mitigation techniques moving cooling spot and moving heating spot were investigated in thin welded sheet structure using FEA. Thermo mechanical analysis and simulation of the processes were performed by ANSYS. The obtained results show different residual stresses behaviour developed during welding, the residual stress magnitude were minimized in both used techniques especially in trailing heat sink welding process. The out of plane distortion results show successfully eliminating of cambering distortion, it is also found that the effective elimination are based on the proper position parameters with respect to the welding heat source.
