Method for detecting and locating cracks in thermally joined components and joining workstation

Abstract

The invention relates to a method for detecting and locating cracks (1) in thermally joined components (2), comprising the steps of acoustically coupling at least one sound sensor (3, 3.1, 3.2, 3.3) to a component (2) in which at least one crack (1) is to be detected and located, of detecting a first sound event characterizing crack formation by means of the at least one sound sensor (3, 3.1) at a first time point, as well as detecting a second sound event characterizing the same crack formation by means of the at least one sound sensor (3, 3.1) at a second time point or the first sound event by means of at least a second sound sensor (3.2) at the second time point, and of determining the distance between the location of the sound origin of the first sound event and at least one detection point of the at least one sound sensor (3, 3.1, 3.2, 3.3).3) from the speed of sound, the first time point and the second time point. The invention also relates to a joining workstation (4) for carrying out the method.
