Abstract

The study of longitudinal shrinkage in butt weld joint and weld bead M. Iranmanesh & S. Babakoohi Hormozgan University, Iran Abstract This research considers longitudinal shrinkage of two steel plates with identical thickness joined throught butt welding and one steel plate with bead welding . This study begins with the introduction of a model in which the thermoelastoplastic zone near to the weld line is simulated with a thermoelastoplastic flat bar; and full-elastic area beyond the weld line is simulated with a full elastic springs, by proposing the physical terms of the model and favorite presumption; the related equations are solved and eventually the conclusion is a relation that can be used for calculating the amount of longitudinal shrinkage with acceptable accuracy . 1 Introduction In the welding process, the heating and cooling cycle causes shrinkage in both base metal and weld metal and subsequently shrinkage forces tend to cause distortion in members and /or metal structures.
