管端自动超声波探伤系统设计与实现

Design and Achievement of Tube-End Ultrasonic Flaw Detection System

为了避免钢管在线自动超声波探伤过程中管端检测盲区切除的资源浪费以及补充管端人工探伤引起的成本增加,设计研制了一套管端自动超声波探伤系统。此探伤系统采用托辊装置带动钢管原地旋转、探头组沿钢管轴向移动的扫查方法,通过PLC控制带动钢管原地旋转的变频器和带动探头组前后移动的伺服电机实现对钢管管端的无盲区探伤检测,在确保钢管质量的同时提高了生产效率。

In order to eliminate the untested area and avoid added artificial detection, a tube-end ultrasonic flaw detection system is designed. The scanning method of this detection system is using roller device drives the steel pipe to spin around and the probe group moves along the axial of the steel pipe. A tube-end UT without blind spot is carried out through invert- er drive the steel pipe to spin around and servo motor drive the movable probe group to move back and forth, which are both controlled by PLC. So the quality of the steel pipe and production efficiency are both improved.
