The Ultrasonic Phased Array Inspection Technology Used in Tubular Joint Welds of Offshore Platform Structures

Aimed at the practical requirement of tubular joint wel ds inspection of offshore platform structures, the ultrasonic phased array inspection algorit hm for offshore platform structures is proposed in this paper, and the ultrasonic phased array inspec tion system for offshore platform structures is developed. The experiment of tubula r joint model is performed with the ultrasonic phased array inspection system for offshore platform structures, the flaws characteristic could be exactly estimated and the flaw s size could be measured through ultrasonic phased array inspection software system. Expe riment results show that the ultrasonic phased array inspection algorithm for offshor e platform structures is feasible, the ultrasonic phased array inspection system could detect fl aws in tubular joint model, the whole development trend of flaws is factually imaging by the ul trasonic phased array inspection technology of offshore platform structures.
