In Fig. 3 the carbide distribution at the top surface (a1, b1) and in the cross-section (a2, b2) is shown for both materials.
After macro laser polishing both materials showed a significantly smaller hardness of 359 ± 12 HV0.01 at the top surface.
For both materials a wide variance of the hardness was measured in the heat affected zone and in the substrate.
A homogenizing effect of macro laser polishing was demonstrated for both materials, creating a homogeneous, inclusion- and segregation free remolten surface layer.

Materials and Experimental In order to obtain a reliable weld metal of various chemical composition fractions, TIG welding was utilized beforehand to make up test pieces by changing feeding speeds of two filler wires of Inconel600 and SUS347.
Table 1 shows the chemical compositions of materials used in this experiment.
Diameter of both wires is 1.2mm and the material of base plates is SUS347.
