The article demonstrates an effective solution for ultrasonic quality monitoring of transmission and drive components of motor vehicles, joined using an innovative method called magnetically impelled arc butt welding (MIAB). The major challenge was the application of ultrasonic technology for quick and reliable testing of thin-walled components with complex geometry. To solve this problem the idea of using ultrasonic subsurface waves was investigated. By using finite elements method (FEM) the angle of the ultrasonic beam incident on the tested element and the frequency of the ultrasonic transducer were verified. Then, scanning acoustic microscopy (SAM) and X-ray computed tomography (CT), both nondestructive tests on thin-walled welded tubular components were performed. The research have shown that it is possible to detect defects with diameter of 0.3 mm with the angle of incidence of wave 31.5°. The results of the numerical analysis were compared with the experimental approach and confirmed the usefulness of proposed method. Finally, the potential of using immersion ultrasonic technique for quick and reliable validation of thin-walled tubular components was proven, as the test duration for a one elements was around 3 s.

浸入式超声波技术对 MIAB 焊接薄壁管件焊接缺陷的检测

本文展示了一种有效的解决方案,用于对机动车辆的传动和驱动部件进行超声波质量监测,并使用一种称为磁力电弧对焊 (MIAB) 的创新方法进行连接。主要挑战是应用超声波技术对具有复杂几何形状的薄壁部件进行快速可靠的测试。为了解决这个问题,研究了使用超声波次表面波的想法。通过有限元法(FEM)验证了超声波束入射到被测元件上的角度和超声波换能器的频率。然后,对薄壁焊接管状部件进行了扫描声学显微镜 (SAM) 和 X 射线计算机断层扫描 (CT) 两种无损检测。研究表明,当波的入射角为31.5°时,可以检测出直径为0.3mm的缺陷。数值分析的结果与实验方法进行了比较,并证实了所提出方法的有效性。最后,证明了使用浸入式超声技术对薄壁管状部件进行快速可靠验证的潜力,因为一个元件的测试持续时间约为 3 秒。
