Combined with the steel bar automatic flaw detection, the relevant problems for steel bar surface and in?ternal cracks were systematically analyzed using eddy current and ultrasonic detection method. After the analysis of de?sign of nondestructive detection method and detection system for bar, according to the actual situation and the inspec?tion requirements of defects of steel bars at site, it was determined to use eddy current and ultrasonic detection method and the overall system design and layout scheme with the advantages of fast speed and high sensitivity, such as the cov?erage rate and sensitivity of steel bars with different sizes, finally a set of automatic flaw detection system for inspecting various defects of steel bar accurately and effectively was designed.
