摘要
通过采用一种新材料 ,制造出了用于焊接球节点钢网架焊缝超声波探伤的超声波横波斜探头 .该探头具有前沿尺寸小、折射角偏差小 ,能够很好地解决壁厚薄、焊缝宽度大的焊接球节点钢网架焊缝探伤的问题 ,并在实际应用中取得了良好的结果 .
Using a new material, the transverse wave angle beam probes in ultrasonic testing of welds for steel space grid structures with welded joints are made. These probes have small front sizes and small errors of refraction angle. These probes can commendably solve the problems of ultrasonic testing of welds with small thickness, large width for steel space grid structures with welded joints. A good result has been obtained in the practical use.
