Title: METHOD AND DEVICE FOR NON-DESTRUCTIVE TESTING AN OBJECT
Abstract:
The invention relates to a method for non-destructive testing an object (1) by means of ultrasound, the method having the following steps: performing a first ultrasonic testing of at least one area of the object based on a first test pattern; and carrying out a second ultrasonic testing of a partial area (100) of the area based on a second test pattern that is more precise than the first test pattern if, during the first ultrasonic testing, at least one amplitude signal (101) having a value higher than a determined threshold value (102) is detected within the partial area (100). The invention also relates to a device for carrying out the method according to the invention.
