The features of defects formation in butt welds, made by flash-butt welding of cast billets of steel 110G13L (GOST 7432-87) with austenite rolled billets of steel 12Kh18N10T (GOST 5949-75), which are used in manufacture of welded railway frogs, were investigated. It was established that casting defects, being located in the butt weld zone, lead to formation of defects and, depending on conditions of their formation, affect the strength properties of welded joints in different ways.
