摘要
Abstract
For the transverse cracks during welding of board steel structure in a certain FPSO project,the ultrasonic testing process and its equipment calibration in the process of finding and assessing these cracks are introduced combining with AWS standards.The different characteristics of waveform and amplitude between longitudinal scanning and transverse scanning for transverse cracks are introduced in detail,and the echo characteristic of transverse crack is analyzed,which could be the reference for the construction and quality inspection of other similar steel structure projects.关键词
