Abstract
The employment of laser system for very automatized welding processes needs an analysis of physic mechanisms by means of mathematical models that correlate the characteristic quality index of welding to working parameters. In this work we used the Group Method of Data Handling (GMDH) mathematical model in order to correlate, for different kinds of steel, the penetration depth to working parameters, chemical composition and thermal properties of the material. Results showed the very important influence of material composition which, in some cases, can be related to that of the main parameters as beam power and welding speed.
