The distribution of residual stresses associated with a multipass, gas-tungsten arc weld, joining two 2.5%Cr 1%Mo steel plates of thickness 13 mm, has been measured non-destructively by neutron diffraction. The large tensile longitudinal stress (400--500 MPa) in the weld and in the plates immediately adjacent to the weld are balanced by compressive stresses (-150 MPa) in the periphery of the plate. The stress components normal to the plate surface and transverse to the weld are everywhere equal in magnitude. In the fusion zone of the weld, these components are tensile at the top surface and middle of the plate and zero at the back surface of the plate (i.e. near the root pass of the weld). 5 refs.
