安全端异种金属焊缝超声检测中TRL探头的选用及应用技巧

The Selection and Application of TRL Probe for Safe-end Dissimilar Weld Ultrasonic Inspection

摘要: TRL探头(一发一收式双晶纵波探头)由两个晶片构成，可以提高粗晶材料中的检测灵敏度和信噪比，在安全端异种金属焊缝超声检测中存在诸多优越性。

Abstract: The Transmitter/Receiver side-by-side L waves probe (TRL probe) is two crystals structure, improve the coarse grained materials of the detection sensitivity and signal-to-noise ratio. It has many advantage in ultrasonic inspection for safe-end dissimilar welds.
