The study of properties of Ni-WC wires surfaced deposits

In this paper, results of investigations of the effect of welding parameters of metal cored wire arc surfacing (MCAW) on the quality of deposits are presented. Single stringer bead deposits were MCAW surfaced on the dry and metallic clean surface of carbon steel plates S355NL-EN 10113. The wires used were 1.6 mm in diameter type EnDOtec XDO*11-S1 (3.5 kg spool) produced by CASTOLIN Ireland and EnDOtec DO*11-P. Additionally following EnDOtec XDO*11-S1 wire and EnDOtec DO*11-P wire properties were tested: WC granules size (μm), linear density of wire (kg/m), density of wire (g/cm3), density of weld metal (g/cm3).
