Abstract
Integrated comparative studies of the possibility of controlling formation and properties of metal by changing the electric parameters in single-layer arc surfacing were conducted. The materials used were flux-cored electrode wires of 1.8 – 2.8 mm diameter, which were developed for three conditions of material deposition: in shielding gas atmosphere (GMAW), with open arc (SSAW) and submerged-arc (SAW). Metal part of the wires was designed so as to produce deposited metal of the type of heat-resistant tool 25Kh5FMS steel. Studies were conducted in a broad mode range: current of 150...450 A, and voltage of 20...32 В. The optimal ranges of current and voltage were experimentally determined for each material deposition method and flux-cored wire diameter, which ensure sound formation of the deposited beads, minimal penetration depth and dilution of deposited metal by base metal. Respective dependencies of the influence of current and voltage on the deposited bead geometry were plotted. Obtained experimental data can be used in the processes of additive manufacturing at selection of optimal modes of layer-by-layer arc deposition of metal materials – wire arc additive manufacturing (WAAM) of part elements. 11 Ref., 3 Tables, 4 Fig.
