*3.3. Hardness Testing*

In order to determine the hardness of the tested materials, the Rockwell hardness measurement was carried out in five places on the weld face/sheet surface and in four locations on the deposit weld/sheet cross-section using the Vickers method at a load of 1000 g, shown in Figures 13 and 14. Hardness measurement results are shown in Table 8 and Figure 15.
