Some simple guidelines:
Higher heat input means that the zone in which residual weld stresses are high will
be larger. In addition, compressive stresses a little way away from the weld will
increase, as shown in Figure 15.10.
Thermal cutting produces residual stresses similar to those caused by welding.
If the parts are not restrained for deformations, preheating the parts can reduce the
residual stresses. If, however, the parts are clamped, then the residual stresses will
increase if the parts are preheated.
