1·Can this armor plate be exchanged to welding line?
这列钢板换到焊缝处好吗？
2·This welding line should be gouged and welded again before tightness inspection.
这条焊缝在密性检查前要碳刨、再焊。
3·The steel with discontinuous flowline microstructure has lower grooving corrosion susceptibility and only single corrosion groove exists along the welding line.
而不连续流线组织的钢板具有较低的沟槽腐蚀敏感性，在焊缝处产生单腐蚀沟槽。
4·It was examined that the dynamic peculiarity, the welding line flaw, the size of steel member section and the rusty phenomenon of an existing municipal steel-box girder bridge.
对某在用市政钢箱梁桥的动力特性、焊缝缺陷、应力和变形、钢构件截面尺寸和锈蚀情况进行了检测，按规范要求验算了结构的整体稳定和局部稳定。
5·The probe choices for ultrasonic crack detection of welding line of light sheet are discussed from two aspects of theory and practice.
从理论和实践两方面探讨了薄板焊缝超声波探伤探头的选择方法。
