The article makes references and appreciations regarding the technologies of surface thermal treatments with electromagnetic fields and the specific treatment facilities. Their development has grown in recent years due to factors of an economic, technical and ecological nature. As such, the large construction diversity determines the classification of these facilities according to a large number of criteria, but a common requirement is the technological flexibility, in conditions of increased productivity and quality. The article also highlights the features of a superficial optical pulse treatment method used by one of the authors in an extensive experimental program
