Abstract

The paper presents the results of investigation of the microstructure of welded R260 steel with GX120Mn13 cast steel and X10CrNi18-8 steel. The analyzed materials had characteristic microstructure types. In the case of welded joints next to the fusion line, the phenomenon of liquid metal penetration along grain boundaries was observed, which is caused by the lower melting temperature of austenitic materials in relation to pearlitic steel. In addition, the heterogeneity of the chemical composition of austenitic materials related to the mixing of materials during welding was identified in this area.
