Blind area in the inspection of butt weld joints using TOED technique was studied by theoretical analysis and experiment. 理论分析与试验验证相结合,研究分析了TOFD技术在检测对接焊接接头中的盲区。
By the analysis and measures above, it improves the test quality of the process piping butt weld effectively. 通过以上分析和采取的措施,能有效提高工艺管道对接焊缝(BW)超声波检测的质量。
A study of the improvement of the butt weld groove of a boiler set box and pipe 锅炉集箱和管道对接焊坡口的改进研究
This indicated that the fracture had initiated at the unfused butt weld in the longitudinal stiffener. 研究表明裂纹是从纵向加劲助未熔透的对接焊缝(BW)中起始的。
Considering the characteristics of the process piping butt weld, this article analyzes the welding methods, the welding positions and the defects which are easily produced. 针对工艺管道对接焊缝(BW)的特点,对焊接方法、焊接位置及易产生的缺陷进行了分析。
