Paper Abstract

Laser technology is one of the technologies the most highly developed at present; however, its wide introduction is constrained, on the one hand, by complexity and the high cost of the equipment, and, on the other hand, by complexity and insufficient knowledge about processes of laser welding, cutting and surface processing, as well as shortages of qualified staff. In spite of these reasons the technologies of laser processing of materials have reached such a level of development that their further perfection on the basis of accumulation of the empirical information has become impossible, whereas technological opportunities of such ways of laser processing, such as welding, cutting, melting and marking, are not completely used. For their successful realization it is necessary to choose the optimum mode of processing, but it is impossible because of the shortage of knowledge about the physical nature of given technological processes, as practically all existing information on these processes has qualitative character. On the other side, to provide the high quality and stability of treatment results it is necessary to have realization of the current monitoring and control during the most technological processes. For this purpose CAD and CAM systems are necessary, the absence of which is explained by the fact that for the present the physically adequate theoretical descriptions of laser technological processes are missing, and the experimental data, by virtue of non-systematic use of experimental work, does not give a complete experimental picture of the physical phenomena, proceeding at laser processing of materials.
