The article presents test results concerning the welding procedure qualification of the production welding of heat-resistant cast steel GX40NiCrSiNb35-25 (1.4852) performed using filler metal WZ 25 35 Zr according to PN-EN ISO 14343. The welding procedure qualification test was performed in accordance with PN-EN ISO 11970. The test joint made using the TIG method (141) was subjected to non-destructive and destructive tests enabling the identification of the mechanical properties of the joint. The test results satisfied the requirements contained in PN-EN ISO 11970 and constituted the basis enabling the preparation of a related welding procedure qualification report.

Przedstawiono wyniki badań kwalifikowania technologii spawania produkcyjnego odlewu staliwnego żaroodpornego w gatunku GX40NiCrSiNb35-25 (1.4852) przy użyciu materiału dodatkowego w klasie WZ 25 35 Zr wg PN-EN ISO 14343. Badanie kwalifikowania technologii spawania wykonano zgodnie z normą PN-EN ISO 11970. Złącze próbne wykonano metodą 141 (TIG) i następnie przeprowadzono badania nieniszczące oraz niszczące określające własności mechaniczne złącza. Wyniki badań spełniły wymagania zawarte w PN-EN ISO 11970 i były podstawą do wystawienia protokołu kwalifikowania technologii spawania.

The article presents the qualification process concerned with the following procedures: finishing welding of aluminium castings pursuant to PN-EN ISO 15614-4, production welding of steel castings pursuant to PN-EN ISO 11970 and production- and finishing welding of cast irons pursuant to PN-EN ISO 15614-3. The work enumerates the cases of qualification of welding procedures for aluminium, steel and iron castings and presents details related to test joint designs as well as the manner of their preparation taking into account welding conditions and other technological aspects. The text also contains precise characteristics of test joint examinations and their range of application while qualifying a given welding procedure. In addition, the article informs about test results which justify the qualification of a finishing welding procedure for aluminium castings and test plate butt joints in case of cast irons and cast steels. In all cases particular attention was paid to the range of qualification of procedures for characteristic conditions of the welding process and its basic variables.
