Features of the Structure Formation at Laser and Laser-Arc Deposition from Aluminum Wire

The paper presents the results of an investigation of additive technology of direct growth from aluminum wire using various thermal sources-a laser and a combined laser arc. In the course of the work, the parameters of the regimes are selected, which ensure an even-dimensional formation of a thin wall during successive layering. The results are presented on the measurement of microhardness and chemical analysis.
