建筑钢结构的某些重要构件虽然采用部分熔透的焊缝,但由于其使用条件的特殊性,设计也会将其定为二级焊缝,需要对其进行超声波探伤,以保证其质量满足施工要求。本文通过工程实例,介绍了钢结构部分熔透焊缝的超声波检测分析方法,以供同行参考。 Although some of the important components of the steel structure of the building are partially permeable, the design will be classified as a secondary weld due to the special conditions of its use. Ultrasonic flaw detection is required to ensure its quality Construction requirements. This article through the engineering example, introduced the steel structure partial penetration welds ultrasonic examination analysis method, for the colleague reference.
