ANALYTICAL PREDICTION OF DISTORTION IN WELDED STRUCTURES

A number of different methods for calculating the distortion that occurs during the fabrication of a welded structure are investigated. The problem of temperature distribution in complex-shaped weldments is considered and calculations are made using a finite element method. A finite element method is then used in a preliminary investigation of distortion, taking into account the phase transformation of high tensile strength steel. One-dimensional approximation methods are reviewed and one of them is used in the calculation of the longitudinal distortion that forms during the fabrication of T-shaped beams. This new coded one-dimensional program is used to study two ways of reducing the distortion when welding built-up beams. The two methods studied are the clamping method and the differential heating method. The results of the analytic study are compared with the data collected during recent experimental work at the Massachusetts Institute of Technology.
