| 摘 要： | 用不同横波、纵波探头对双U型坡口奥氏体不锈钢焊接接头试样进行超声波检测 ,发现粗大有序的焊缝组织是引起声波衰减严重和杂波反射强的原因。实验结果表明 ,双U型焊缝超声波检测的结果比单U型坡口焊缝复杂 ,窄脉冲探头的信噪比优于普通探头 ,纵波斜探头优于横波探头 ,信噪比可达 12dB。 |
| 关 键 词： | 超声检测 窄脉冲 探头 奥氏体 信噪比 |

| Abstract: | Different transverse waves and the longitudinal wave probes is carried on the ultrasonic examination to double U-butt austenite stainless steel weld specimens. The coarse grain structure of welds results in heavy attenuation of ultrasonic and powerful reflection of noise . Ultrasonic examinations of the double U-butt weld results are more complex than single U-butt weld. The short-duration pulse longitudinal probe signal-to-noise ratio is better than the ordinary probe, signal-to-noise ratio attainability 12dB. |
| Keywords: | ultrasonic testing short-duration pulse probe austenitic signal-to-noise ratio |
