Longitudinal residual stresses in a butt weld. Area=
In the case of thin-walled components, exposed to a risk of buckling, considerations
must be taken to the reduction in buckling resistance as a result of the area containing
residual compression stresses, as shown in Figure 15.10.
When designing to resist fatigue and brittle failure, considerations must be taken to
the longitudinal residual tensile stresses around the weld.
Residual stresses can be partly reduced by stress-relieving the component while
allowing it to expand.
Producing the welds in such a sequence that the parts of the workpiece can move
during the welding operation can reduce the residual weld stresses.
