Analiza morfologii przełomów udarnościowych złączy spawanych ze staliwa dla energetyki typu Cr-Mo z dodatkiem metali ziem rzadkich

Abstract

The article presents the results of tests of butt welded joints, ie. hardness distribution, macro and microstructure. Analysis of surface morphology of impact fractures of G17CrMo5-5 welded joints was carried out. The welding process was carried out on two types of melts, ie. without modification and with addition of rare earth metals (REM) to liquid metal. Welded joints were made using the TIG method.
