钢结构T型焊接接头超声波探伤的方法及其案例分析

为了提高T型焊接接头超声波探伤的准确性,确保钢结构的使用安全,本文依据相关标准、工作实践,并结合探伤案例分析,提出了采用双晶探头（当翼板较厚时采用直探头）和斜探头组合的方法在翼板上进行探伤。该方法以双晶探头探伤为主,斜探头为辅,两种探头对同一个缺陷进行定位,判断准确,避免漏检和误判,而且检测速度快。

Steel Structure T Weld Joint Ultrasonic Testing Method and Case Analysis

In order to enhance the T weld joint ultrasonic testing accuracy and guarantee the steel structure security, based on the standard,the working practice and combining with the theoretical analysis of the crack detection case,a combine method of using twin crystal probe head(when lifting surface is thick,the straight probe head was used) and slanting probe head to carry on crack detection was proposed in this paper.The twin crystal probe head is primarily and slanting probe head is auxiliary in this method.Tw...
