An ultrasonic phased array testing wedge for testing v-shaped corner workpieces

Abstract

The invention discloses an ultrasonic phased array detection wedge for detecting V-shaped corner workpieces, which comprises a wedge body, a sound-absorbing layer and a probe seat; the shape of the wedge body is a triangular prism, and the upper and lower sides of the triangular prism The bottom surface is a right-angled triangle; a probe seat is provided on the side where one of the right-angled sides is located, and the probe seat and the wedge body are integrally formed, and a plurality of threaded holes are provided on the probe seat; a sound-absorbing layer is provided on one side of the wedge body; The shape of the sound-absorbing layer is trapezoidal, and there is a sawtooth-shaped area inside it, including sound-absorbing materials; the present invention avoids the waveform conversion and multiple reflection attenuation of ultrasonic waves to the greatest extent, so that the sound wave energy is more concentrated and reaches the defect site The sound energy is greater, so as to achieve the best flaw detection effect.

Description

technical field [0001] The invention relates to an ultrasonic phased array detection wedge for detecting V-shaped corner workpieces, belonging to the field of non-destructive flaw detection. technical background [0002] Ultrasonic phased array detection has been widely used in nuclear power, chemical industry and other fields due to its advantages of high detection reliability, good detection resolution, fast detection speed and high detection efficiency. Defect detection plays an important role. When ultrasonic phased array technology is used in the industry to perform non-destructive testing on workpieces, in order to prevent the phased array probe from being worn out, and to allow the ultrasonic waves emitted by the probe to enter the workpiece at a specific angle, relevant wedges will be installed at the bottom of the probe. achieve the above purpose. [0003] The actual detection method is often affected by the shape of the workpiece, and the V-shaped corner workpiec...

Problems solved by technology

[0005] In order to solve the problem that the V-shaped corner workpiece cannot be fully detected in the actual ultrasonic phased array detection process, the present invention provides an ultrasonic detection wedge, which overcomes the V-shaped corner workpiece that cannot be matched between the wedge and the V-shaped corner workpiece in the prior art. The problem of missed inspection of the top corner of the shaped corner workpiece
