Title:
Abstract:	Zur Charakterisierung der ermüdungsrelevanten Werkstoffveränderungen infolge hochfrequenter Schweißnahtnachbehandlung hat sich der Einsatz von mikromagnetischen Werkstoff- und Spannungsanalysen vorteilhaft gezeigt. Für Standardbauteile hat sich gezeigt, dass die Qualitätssicherung der Nachbehandlung mit höherfrequenten Hämmerverfahren bei Einhaltung der Behandlungsparameter durch eine Sichtkontrolle möglich ist. Das Mikromagnetische Verfahren ermöglicht bei neuen Anwendungsfällen eine Gütekontrolle der Nachbehandlung an Arbeitsproben ·und am Realbauteil. A measurement technique for inspection of material subsurface changes after mechanical surface treatment. The micro-magnetic stress and material analysis has shown to be advantageous for characterizing the fatigue related material properties after high frequency post weld treatment. The quality control of standard parts treated by high frequency hammer peeing with the same peening parameters is possible by means of visual inspection. For new applications, the micro-magnetic analysis provides a quality control of post weld treated work samples and real components.
