摘　　要：对直径12~25 mm原材料圆钢的超声波探伤。为了不受盲区限制和噪声干扰,采用联合双晶探头检测。介绍了联合双晶探头的工作原理,用于圆钢探伤的探头晶片尺寸,探头频率,探伤灵敏度调试及影响检测结果的因素等。Ultrasonic flaw detection for raw round steel with diameters from 12 mm to 25 mm.In order not to be restricted by the blind area and noise interference,the joint dual-element probe is used for flaw detection.This paper introduces the working principle of the combined dual-element probe,the probe wafer size,probe frequency,detection sensitivity adjustment and factors affecting the detection results for round steel flaw detection.
