Abstract

This paper deals with the simulation of the heat input of a welding source. The heat source is modelled by spatial Gaussian functions which are introduced into a fully nonlinear heat transfer analyser for the investigation of the transient temperature fields in welded connections. The energy supplied by the welding arc together with the absorbed energy and the concentration of the heat source are relevant parameters to reproduce numerically the shape of the molten zone and the dimensions of the welding pool. If these dimensions are known from an experiment, the procedure presented permits to model correctly the heat input and hence the whole phenomenon. A practical example is shown which demonstrates the capability of the method.
