Abstract
위상배열 초음파 탐상을 위한 기본 보정시험편으로 탐촉자의 입사점, 굴절각 측정, 시간축 보정이 가능하며, 감도보정 대비시험편과 스텐레스강/듀플렉스강용 감도보정 대비시험편으로 감도보정과 DAC 작성이 가능한 효과를 가진다. 검증용 시험편으로는 방향성을 가진 결함에 대해 한쪽 면에서 검사를 실시하였을때 검출이 가능한지 검증이 가능한 효과를 가진다. 일반적인 초음파 탐상법에 있어서 규격에서 정의되고 있는 보정시험편에 비하여, 위상배열 초음파 탐상에서는 보정시험편이 정의되지 아니하였으나 본 발명에 의해 적절한 보정시험편과 이를 이용한 보정의 방법이 제시되게 된다.
