摘　　要：由于爬波受工件表面粗糙的影响不大,同时具有对表面和近表面缺陷非常敏感的优点,使爬波检测成为常规超声波检测的有力补充。综合目前国内外的研究进展,列举了爬波在支柱瓷绝缘子、焊缝和螺栓裂纹等检测方面的应用,所有实例均表明爬波检测在这些方面的有效性。随着爬波理论研究的深入和检测仪器的发展,爬波在无损检测领域的应用必将越来越广泛。Due to being less influenced by surface roughness and being sensitive to surface and sub-surface defects, creeping wave testing has become an effective supplement to conventional ultrasonic testing. The application of creeping wave in the testing fields of strut porcelain insulator, welding and bolt was introduced, on the basis of current research progress at home and abroad. Its effectiveness in these fields was proved by all the testing cases. With the further research and experiment for the creeping wave theory and testing instrument development, creeping wave testing shall be applied more and more popularly in nondestructive testing.
