Using the cold metal transfer (CMT) method for wire arc additive manufacturing (WAAM) applications

Abstract

This work deals with the possibilities of applying the MAG-CMT welding method for the purpose of wire arc additive manufacturing (WAAM). The WAAM method was operated using an industrial robot and welding device for MAG welding. The aim of the work was to compare three methods of laying layers in order to assess their mutual mixing. Cross-shaped perpendicular walls that were mutually connected as of the welded component were assessed. The geometry, macrostructure, and total operating costs of individual variants were evaluated. The result was the determination of the most accurate and most economical variant of laying layers.
