PREDICTING SHRINKAGE AND DISTORTION IN A WELDED PLATE
Computer models of the behaviour of flat plates during welding have been developed to improve understanding of the mechanisms by which distortions arise. The models allow the key variables to be identified from which simple formulae relating distortion to weld conditions, plate dimensions and material properties may be derived. The paper presents a number of these equations and examines their validity for the prediction of various types of weld distortion, i.e. transverse shrinkage, angular distortion and longitudinal shrinkage. Theoretical results are compared with test data. Order from BSRA as No. 49,597.
