The methods of additive techniques of layer-by-layer laser agglomeration of powder materials at a direct injection and mechanical powder feed are considered. A method for layer-by-layer surfacing with a scanning laser beam is offered. The paths of scanning on a line, ellipse and a circle are analyzed. Samples are processed and investigations on an influence of a processing velocity and the paths of scanning upon geometrical adjectives of layers obtained are carried out. The investigation results obtained allowed drawing a conclusion of the optimality of a scanning path of a laser beam on an ellipse, on geometrical adjectives and a coefficient of powder use.
