Abstract
The paper presents the results of qualification of produc- tion welding procedures for heat-resistant cast steel in grade GX40NiCrNb35-45 with used filler material in grade WZ 35 45 Zr (PN-EN ISO 14343). Qualification of welding technology was made in accordance to PN-EN ISO 11970. Test welded joint was made using 141 method and non-destructive and destructive testing were performed in order to determine the mechanical properties of the welded joint. Completed tests met the requirements of PN-EN ISO 11970 and were the ba- sis of the welding procedure qualification record.

Spawanie produkcyjne odlewu staliwnego żaroodpornego GX40NiCrNb35-45
W pracy przedstawiono przykładowe wyniki badań kwalifikowania technologii spawania produkcyjnego odlewu staliwnego żaroodpornego w gatunku GX40NiCrNb35-45 przy użyciu materiału dodatkowego w gatunku WZ 35 45 Zr wg PN-EN ISO 14343. Badanie kwalifikowania technologii spawania wykonano zgodnie z PN-EN ISO 11970. Złącze próbne wykonano metodą 141 i następnie przeprowadzono badania nieniszczące oraz niszczące określające własności mechaniczne złącza. Wykonane badania pozwoliły spełnić wymagania zawarte w PN-EN ISO 11970 i były podstawą do wystawienia protokołu kwalifikowania technologii spawania.
