Determination of shrinkage of weld

A calculation-experimental technique of determination of weld shrinkage is described in that work. Experimentally, with the help of strain gauges, residual stresses are determined at two points, which are at known distances from the weld. Shrinkages are found out from the theoretical solution of the plane elasticity theory about the insertion of bodies with interference. Calculations have been carried out for experimental studies of a weld 400 mm long for different thicknesses of metal. It is found that when the thickness of the metal increases, the shrinkage values also increase. This is due to the fact that as the thickness of the metal increases, the heat input required to penetrate it also increases.
