The Research of Models for TKY Tubular Joint Welds in Ultrasonic Phased Array Inspection

Abstract:

In order to solve the problem of locating defects from TKY node structure weld using for marine engineering , the article present a new approach of establishing TKY’s mathematical model to replace the traditional method of Graphic analytic method, which uses the computer to carry on the drawing. Firstly three-dimensional mathematical model of the Y-shaped tube node is made, based on what it work out the equation of the cross-sectional on different position of weld by introducing the concept of intersecting angle φ, eventually it establish the two dimensional mathematical model of cross-sectional . In the end of the article, some experimental examples show the effectiveness of the models, which testify that using computer graphics to evaluate ultrasonic pulse-echo is more effective , smaller error, higher working efficiency and reduces the impact of human factors greatly.
