Effect of welding methods on the magnitude of residual stresses in welding up cracks in grey cast iron casing components

It is shown that the magnitude of residual stresses in welding up cracks in casing components is not sufficient to distort them and depends on the welding method. The behaviour of the residual stresses is the same for all methods investigated in these investigations. The deformation work of a welded...

Summary:It is shown that the magnitude of residual stresses in welding up cracks in casing components is not sufficient to distort them and depends on the welding method. The behaviour of the residual stresses is the same for all methods investigated in these investigations. The deformation work of a welded joint in tensile or shear loading depends on the welding method and determines the probability of formation of weld zone cracks.
