近年来，微电子和计算机技术飞速开展，促成了集相控阵信号发生、数据处理、显现和剖析等功能于一体的相控阵仪器的开展。跟着国内外（美国ASME、国际标准ISO以及我国GB和NB）相控阵超声检测标准的完善，相控阵超声检测已广泛应用于海工、船只、航空航天、石油化工、火电、核电等职业。

在设计时，关于海上油气工厂（FPSO）上建模块中资料为A790-S31803，标准为直径610mm，壁厚46mm的管线环焊缝，需求进行射线检测。因为射线具有电离辐射，对检测人员的人身安全损害严峻，故在管线合拢拼装的过程中，不能实现射线检测中心曝光，然后降低了射线检测功率，影响项目进展。因而，承建方、检测公司、业主和监造方进行洽谈后，主张选用相控阵超声检测替代射线检测进行现场检测。在施行相控阵超声检测前，需求运用带缺点的模仿试块进行校准，以确认检测成果的可靠性。

试样的制造

试样包含灵敏度对较量块和用于验证的人工缺点模仿试管。

灵敏度对较量块的制造

依照标准ASME BPVC.V-2019《锅炉及压力容器标准第V卷无损检测》第4章焊缝超声波查验办法中校准试块的要求，加工了两种灵敏度对较量块。

图1 灵敏度对较量块什物

如图1(a)所示，在原资料上加工长横孔反射体，制造原资料灵敏度对较量块，用于楔块推迟的校准。

如图1(b)所示，依照焊接工艺焊接后进行切开，制造带有焊缝的长横孔和刻槽的灵敏度对较量块，用于灵敏度校准和TCG（时刻校对增益）曲线的制造等。

反射体（长横孔和刻槽）的具体参数如下：
