The article presents preliminary results of microwelding thin sheet occurred of superalloy H 230®. There were shown the possibilities of combining thin metal sheet using resistive pulse microwelding. The joints were made using a device to microwelding SST WS 7000s. For characterizing of the obtained weld tests properties there were examined mechanical properties like: measuring the microhardness, stretching test and microstructure observation. Microhardness measurements of the joints and base material where taken using Matsuzawa Vickers MX 100 type with applied load 100G (0,98 N). Stretching test where made on Zwick/Roell Z100 machine with applied load 10kN. To observe mentioned joints, metallographic microscope Nikon Eclipse MA2000 was used. The studies determined the basic parameters of microwelding thin sheet of joint made and the quality of the weld. The results showed that there is a possibility of obtaining the satisfying quality joint using micro welding between the thin sheet from superalloy H 230®.
