浅析可记录的脉冲反射法超声检测-相控阵检测技术

A Brief Analysis of Recordable Pulse Reflectometry Ultrasonic Testing-Phased Array Detection Techniques

超声检测包括衍射时差法超声检测(TOFD)、可记录的脉冲反射法超声检测和不可记录的脉冲反射法超声检测,当采用不可记录的脉冲反射法时,根据规范,还需要增加其他检测,影响检测效率,增加检测成本。应用可记录的脉冲反射法超声检测,则不需要增加其他补充检测,就以上问题作出陈述,分析,推动可记录脉冲超声检测的发展。

Ultrasonic testing includes Diffraction differential ultrasonic testing(TOFD),Recordable pulse reflectometry ultrasonic testing and non-recordable pulse reflectometry ultrasonic testing.When unrecordable pulse reflectometry is used,radiographic or diffraction differential ultrasonic testing should also be used as an additional local test.In testing,how to define recordable and unrecordable,this article will state and analyze the above problems,and promote the development of recordable ultrasonic testing.
