摘要
研制了全自动涡流螺栓检测系统。系统采用多个探头移动扫描,螺栓同时旋转,头部呈锥角的自比差分点探头及阻抗平面显示技术,实现对螺栓包括头杆结合部、光杆和螺杆处的纵横裂纹全方位检测。
An automatic eddy current system was developed. The differential probe with a cone head and impedance plane display technique were used. And a spinning bolt was scanned by several probes moved to realize all-side inspection for longitudinal and transverse cracks.
