Approach to arc fusion welding main parameters optimization

In this paper, approach to arc fusion welding main parameters optimisation is explained, based on simplified solutions of Fourier differential equation of heat conduction and on some empirical data from practice. Welding voltage, current and welding speed are called main parameters of arc fusion welding process, due to fact that they have very important influence on the weld shape and dimensions, and also on different properties of the welded joint. Because of growing demands from the quality, reliability and safety point of view, the need for continuos improvement of approach to optimisation of main welding parameters is emphasised. Beside that, the need of optimal utilisation of modern welding power source and modern welding equipment, and also application of computer technologies on the field of optimisation of main welding parameters and also on the field of welding technologies, in general, is emphasised too. Model for optimisation of main welding parameters is given in a form of block diagram.
