AI Technical Summary

Technical Problem

The uneven wall thickness of square steel causes changes in the surface spacing between the eddy current flaw detector and the square steel, affecting the detection accuracy.

Method used

A square steel eddy current detection device is designed, adopting a combined structure between the roller and the first spring. The roller rolls along the square steel to maintain contact with the square steel surface to ensure the effective detection distance between the eddy current flaw detector and the square steel.

Benefits of technology

By maintaining a constant detection distance, the accuracy of square steel surface defect detection is improved and is suitable for detection of different wall thickness positions.
