Present investigation has been directed toward evolving a quantitative relationship between shrinkage distortion and factors which create them, when a weld bead has been deposited along one edge of a flat steel plate. Theoretical calculations were performed based on the incremental theory of thermoplasticity by the aid of digital computer. in order to evaluate effects of heat input on the values of residual stresses and shrinkage distortion. We derived an approximate formula to estimate the amount of final deflection, which is similar to that developed by N.O. Okerblom and J.C. Walter based on a somewhat simplified assumption. Consequently, it is shown that the longitudinal shrinkage distortion increases nearly in direct proportion with increase in the amount of heat input during welding.
