船舶T型角焊缝横向裂纹的超声波检测

Ultrasonic testing research ship T-fillet weld transverse crack

为了提高船舶T型角焊缝横向裂纹的检出率,采用横波探头在面板上平行焊缝正、反两个方向扫查和在焊缝表面沿着焊缝正反两个方向扫查的检测方法,结合抗裂试板进行横向裂纹检测后解剖分析。结果表明,每个检测面都有各自的检测特性,应采用横波探头在面板上平行焊缝正、反两个方向扫查,横波腹板全声程扫查,在焊缝表面沿着焊缝正反两个方向扫查的检测方法。

In order to improve ship T-fillet weld detection of transverse cracks,using shear wave probe on the panel seam parallel positive and negative scanning,or in both directions along the surface of the weld seam detection methods both directions in scanning,crack test panels combine anatomical analysis of transverse crack detection.Studies have shown that：Each detector has its own face detection feature,the probe should be parallel transverse welds on the panel forward and reverse scanning in both directions; transverse webs full sound scanning process,the surface along the weld seam detection method of scanning both directions.
