Purpose: Investigation results are presented of the effect of main parameters of laser powder surfacing of the Si-Mo spheroidal cast iron with the nickel based powder on quality and shape of padding welds and portion of the substrate material in the padding weld. Design/methodology/approach: It was shown basing on investigation of the process of laser powder surfacing with the nickel based powder onto the spheroidal cast iron substrate that it is feasible to make high quality padding welds in the relatively wide range of parameters. Findings: Investigation results presented in the paper were carried out to determine quality of padding welds applied by laser powder surfacing with the nickel based powder onto the alloy spheroidal cast iron and especially to determine the padding welds adhesion to the substrate. Practical implications: It is possible to control the portion of the substrate material in the padding weld with high accuracy in a wide range from even a few per cent, by the relevant setting of the line energy of the laser beam and the powder feed rate. Originality/value: The developed implant test makes the qualitative and quantitative assessment possible of the adhesion of the padding weld to the substrate, Table 5, Figs. 7 to 11. All padding welds made within the range of the optimum welding parameters demonstrated very good adhesion and the break, depending on the nickel padding weld thickness, occurred in the fusion area or by pulling part of the padding weld out.
