Residual Stresses in Butt and Socket Welded Joints

A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...

Effect of welding parameters on penetration depth in FB-TIG welding of 5083 aluminum alloy

In the present study, effect of current, welding speed and preheat temperature during FB-TIG welding of AA5083 aluminum alloy was studied. Using the Taguchi method, 9 different tests were designed to investigate the effect of welding parameters on the penetration depth. Consistent with predictions, increasing the current and preheat temperature, and reducing the welding speed led to an increase...
