Problems solved by technology

However, in the unmelted and crimped state, since the ultrasonic wave passes (propagates through) the bonding region and is not reflected in the bonding region, the known three-dimensional ultrasonic inspection equipment used in the conventional technology cannot automatically identify the bonded region in the unmelted and crimped state. The inspection object is detected as a welding defect

Abstract

Disclosed is a 3D ultrasonographic device that has more improved examination accuracy than ever before. The 3D ultrasonographic device (10) is equipped with an ultrasonic wave transducer (11) having a plurality of piezoelectric vibrators (20) in an mn arrangement; a signal processing unit (17) that receives an echo in which an ultrasonic wave, which is oscillated from a piezoelectric vibrator (20) that is sequentially selected, is received at the junction (15) of an object to be examined (14) and reflected, and generates 3D image data by detecting the electric signal of said echo and processing the signal; peak detection units (51, 52) that detects the first peak and second peak of the intensity distribution in the depth (z) direction of the 3D image data; a junction image generation unit (36) that generates a 3D image of the junction (15) by mapping the distance in the z-direction of the first peak and the second peak on the x-y plane; a quality assessment unit (37) that assesses the condition of the junction (15) by means of a two-step quality assessment; and a display unit (38) that displays the 3D junction image and the junction quality assessment results for the junction (15).

Description

technical field [0001] The present invention relates to a three-dimensional ultrasonic inspection device, which uses ultrasonic waves to perform non-destructive inspection of the internal structure, the state of the connection area, and the defect state of the object to be inspected, and more specifically relates to a device including a sensor for ultrasonic inspection Three-dimensional ultrasonic inspection equipment of the device, ultrasonic imaging equipment for three-dimensional visualization of the state of the welded part and the state of welding defects of the inspected object. Background technique [0002] An example of a technique that performs non-destructive inspection of the state of the welded portion and the state of welding defects in the connection area between the plate structures, the object to be inspected is the ultrasonic inspection technology. In ultrasonic inspection equipment using ultrasonic inspection technology, ultrasonic waves are irradiated to t...
