Crack tesztrendszer

HPT Hirsch Prüftechnik GmbH and Dr.-Ing. Peter Hirsch have worked on the further development of direct current pulsing technology for the magnetic particle testing (MT testing) and demagnetization of steel parts, and have consequently invented test equipment registered under patent number DE 102 41029B42005.08.25, resulting in receipt of the Rhineland Palatinate Inventor’s Prize in February 2006 as awarded by Investitions- und Strukturbank Rheinland-Pfalz (ISB) GmbH and endowed with a EUR 5,000 prize.
In place of continuous current, steel parts are magnetized or demagnetized using direct current pulsing. In order to reveal cracks or material separations such as fusing or forging defects, these are ideally sprayed with a fluorescent test media, allowing evaluation under a UV LED test lamp even under daylight conditions per EN ISO 9934-1 and documentation with a digital camera.
