Mathematical modelling of the effect of the surface relief of specimens on the localisation of plastic deformation in the pressure welding zone

AbstractThe finite element method is used to analyse the special features of plastic deformation in the weld zone of dissimilar creep-resisting materials produced by pressure welding in the presence of a relief of variable depth on the welded surfaces. The experimental results show that the weld quality can be improved by selecting a larger depth of the relief away from the edges of the welded surfaces.
