The laser beam machining is used as a method able to ensure various changes in the workpiece material as a consequence of the laser beam impact with the workpiece surface layer. The purpose of the paper is to present some results of a research developed in order to characterize the behaviour of some metallic materials under the action of the laser beam. Some theoretical considerations showed that the thermal and optical properties of the metallic materials could influence the effects of the laser beam impact with the test pieces materials. Experimental researches developed on test pieces made of steel, copper, aluminum and bronze proved that only the steel is affected by a laser radiation having a wavelength of 1070 nm and a power up to 300 W.
