Abstract
The invention relates to an ultrasonic probe for the non-destructive testing of metal work pieces, particularly pipes, for transverse defects, comprising a row-shaped arrangement of oscillator elements located on a lead wedge for coupling to the work piece. According to the invention, the lead wedge is designed as a wedge-shaped hollow body, which is filled with fluid and the wedge angle of which is a maximum of 24, and which is arranged on the work piece such that the intromission angle into the work piece is a maximum of 70.
Claims11
An ultrasonic probe for non-destructive testing of a metallic workpiece, for transverse faults, comprising a wedge having a linear array of oscillator elements for coupling ultrasound emitted by the oscillator elements to the workpiece,
- wherein the wedge is formed as a wedge-shaped cavity filled with a fluid and having a wedge angle of maximally 24°, with the wedge being arranged on the workpiece such that an angle of incidence into the workpiece is at most 70°.
