The Ultrasonic Testing of Welded TKY Tubular Joints

TKY tubular joints and similar structure is widely used in steel structure and marine platform,which presents a severe challenge to nondestructive testing technology.For the specific and complicated welding part,UT (ultrasonic testing) is the most useful method so far.With the scientific development and application of new technology,some new nondestructive testing methods and means have gradually applied,such as phased array ultrasonic technology.The context not only reviewed the development condition of UT,but also recommended methods that were appropriate for the TKY tubular joints.Finally,it intended to make prospects for the nondestructive detecting technology in the respect.
