Numerical analysis of welding residual stress and its verification using neutron diffraction measurement
Article Abstract:
Analysis of residual stress in welding joints by direct measurements and computed distributions reveal that the methods agree well with each other and they are suitable for evaluating both internal stress and surface stress.

Residual stress reduction and fatigue strength improvement by controlling welding pass sequences
Article Abstract:
Results demonstrate that the residual stress at the weld toe of the main plate side welding pass is 80 MPa as against 170 MPa in the attachment side welding pass. Data also show that the fatigue strength of the former is higher than that of the latter.

Weld distortion control, during welding process with reverse-side heating
Article Abstract:
An in-process method is developed for controlling welding distortion in fillet welds which reduces angular distortion by performing reverse-side Tungsten inert gas (TIG) heating of the weld line. Various heating conditions are examined by experiment and finite-element analysis in order to determine appropriate conditions and to study the mechanism by which welding distortion is reduced.
