Industrial integration of residual stress measuring NDT-systems based on ultrasonics and micromagnetics
Abstract
For years, Fraunhofer-IZFP has developed NDT methods for the characterization of residual stresses, that have been introduced into industrial practice. These NDT methods are based on micromagnetic and ultrasonic principles. Ultrasonic systems are well integrated in the quality surveillance strategies of the European railway companies. The micro-magnetic systems find their application mainly in the field of the machine-building and the car supplying industry. This contribution reports on these applications and documents the benefits for the industrial user, which are mainly in the context of safety and lifetime.
