Description

{Testing apparatus of auto-scanner for phased array ultrasonic inspection}

The present invention relates to an automatic scanner test device for phased array ultrasonic inspection, and more specifically, to an automatic scanner test device for testing an automatic scanner for phased array ultrasonic inspection that inspects a test object using ultrasonic waves.

In the case of large facilities such as power plants, they are composed of many devices and tubes, and most of these tubes are connected by welding, so when high pressure and temperature are applied to the tubes during the operation of the facility or device, it becomes a safety vulnerability. Defects such as cracks occur at welds, impairing safety, and even in the case of fluid storage tanks such as oil, high pressure is continuously applied to the inner wall, so defects such as corrosion or cracks may occur over time.

As a countermeasure against this, we conduct regular inspections of welded areas of pipes or tank walls or safety inspections during construction.

In such safety inspections, surface inspections, volumetric inspections, etc. are usually conducted depending on the characteristics of the inspection object. Surface inspections include visual inspection and penetrant inspection, and in the case of directly below the surface, magnetic inspection, eddy current inspection, etc. , and volumetric tests such as radiography and ultrasonic tests are performed for defects that exist inside the weld zone.

In the drawing, the thickness is enlarged to clearly express various layers and regions. Throughout the specification, similar parts are given the same reference numerals. When a part of a layer, membrane, region, plate, etc. is said to be "on" another part, this includes not only being "directly above" the other part, but also cases where there is another part in between. Conversely, when a part is said to be “right on top” of another part, it means that there is no other part in between. Additionally, when a part of a layer, membrane, region, plate, etc. is said to be “beneath” another part, this includes not only cases where it is “directly below” another part, but also cases where there is another part in between. Conversely, when a part is said to be "right below" another part, it means that there is no other part in between.

Spatially relative terms should be understood as terms that include different directions of the element during use or operation in addition to the direction shown in the drawings. For example, if an element shown in the drawings is turned over, an element described as “below” or “beneath” another element may be placed “above” the other element. Accordingly, the illustrative term “down” may include both downward and upward directions. Elements can also be oriented in other directions, so spatially relative terms can be interpreted according to orientation.

In this specification, when a part is connected to another part, this includes not only the case where it is directly connected, but also the case where it is connected with another element in between. Additionally, when it is said that a part includes a certain component, this does not mean that other components are excluded, but that it may further include other components, unless specifically stated to the contrary.
