Paper Abstract

In the process of inspection of the surface crackle of small diameter (6mm2Omm) colddrawn steel bar users suffer heavy losses because the surface crackle often passes unfound. At the same time the inspection speed is not high. The research of automatic inspection is based on the principle of surface wave testing making linefocus probe with long crystal to improve the speed ofinspection using microcomputer to control the automatic inspection process and improve the detecting reliability.
