The article discusses technological tests involving the use of the hybrid process (laser + electric arc (MAG)) for the efficient application of layers (surfacing). The objective of the tests was to determine the effect of an additional welding power source (laser beam) on the possibility of increasing a surfacing rate (in comparison with surfacing rates obtainable using the MAG method) as well as on the formation (shaping) of the overlay weld geometry and the degree of dilution (of the base material in the overly weld). The technological tests of the hybrid (HLAW (laser + MAG)) surfacing process involved the use of steel grade 41Cr4 and filler metal grade LNM 307.
