The paper presents, the impact of process variables on connection parameters during micro-welding of H800 superalloy. The research discusses the apparatus and features, including the advantages of the welding procedure. The process variables determining the influence of pulse micro-welding method on the metallographic structure of welds of thin superalloys were given. The process uses a thin sheet of H800 superalloy welded on a C22 alloy substrate. During the experiment, welded joints of tested superalloys were obtained and the characteristics of their microstructure were examined. Welding of thin sheet was made by means of resistive pulse welding using the SST WS 7000s device. The focus was on the leading tested parameters, such as microhardness and observation of the weld microstructure. The aim of experiment was to check the regeneration possibility of heat and mechanically loaded machine parts made of superalloys.
