  • ABSTRACT: The first phase of studying the process of laser-assisted welding necessarily goes through a preliminary theoretical physical-engineering analysis of the roles of the major manufacturing parameters. This is especially important for the practice when new technologies are being developed. This paper deals with the process of laser-assisted welding with a diode laser (λ=808 nm; 940 nm) by heat conduction of lamella packs of electrical steel. On the basis of dependencies and correlations between physical quantities and manufacturing parameters of treatment, concrete numerical calculations of critical power density of melting and evaporation for specific values of welding rate have been presented.
