Purpose: Purpose of this paper: Study of robotized GMA metal-cored wire surfacing of one-, two- and three layers stringer bead and weave bead deposits has been carried out. Design/methodology/approach: The dilution of deposits, structure, hardness, WC carbide morphology and abrasive wear resistance type metal-ceramic as per ASTM G65, was determined. Findings: It was shown that the abrasive wear resistance of stringer bead deposits is higher than weave bead deposits. Study of robotized GMA surfacing process with EnDOtec DO*11 wire of diameter 1.6 [mm], applying weaving (oscillation) technique of surfacing, showed that it is possible to produce high quality of deposits in a wide range of surfacing parameters (heat input). Contrary to stringer bead deposits, weave bead deposits are transverse cracks free which can be caused by thermal stresses in the deposits. Research limitations/implications: The mechanism of deposit formation (shaping), especially the control of dilution, shape of fusion zone and penetration depth, depending on parameters of surfacing and the trajectory and parameters of oscillation of the surfacing torch demands further investigations and detailed studies. Practical implications: The technology can be applied for wear plates manufacturing. Originality/value: Improve of the wear resistance of wear plates.
