High Speed Resistance Welding (HSRW) is a high-volume manufacturing route for the production of welded steel cans. Full optimisation of such a process requires a scientific understanding of the relationships between process variables and thermal effects occurring in the weld zone and heat affected zone. This body of work describes the development of a predictive electro-thermal FE computer model to provide a more profound understanding of the HSRW process. The model has been used to investigate the thermal effects of welding speed and A.C. frequency on the macro-scale evolution of the nuggets developed during welding. Factors affecting weld quality and previous attempts to model the process are highlighted and the evolution of the model is described in detail determining the unsuitability of finite difference to the final Windows based user friendly interface for the validated finite element model. The model formulation and generated results are described and a novel method of using Re-melted Tin Zone measurements for validation is presented.
