| 1. | Cracks have been found in the flange and web splices at groove welds in at least four bridges .
至少在四座桥梁的翼缘板和腹板拼接坡口焊缝中发现了裂纹。 |
| 2. | Often lack of fusion adjacent to the girder web in the transverse groove welds led to the cracking .
在靠近主梁腹板的横向坡口焊缝处常常出现未熔透而导致裂纹。 |
| 3. | The second crack is a crack originating at the groove weld toe of the column flange-girder flange connection .
第二种是产生于立柱翼缘与主梁翼缘连接处的坡口焊缝焊趾处的裂纹。 |
| 4. | A large number of these cracks occurred because the groove welded component was considered a secondary member or attachment .
发生这许多裂纹是因为把这些坡口焊接部件作为次要构件或附件考虑。 |
| 5. | These attachments were considered secondary components, so no weld quality control has been imposed on the groove weld splice .
这些附连件被看作是次要的部件，所以在这种坡口焊接中没有进行焊接质量控制。 |
| 6. | Method of u - groove weld cracking test
U形坡口焊接裂纹试验方法 |
| 7. | Method of y - groove weld cracking test
Y型坡口焊接裂纹试验方法 |
| 8. | Flare groove welding
喇叭形坡口焊 |
| 9. | The paper introduces single " u " groove welding procedure for stainless steel inner cylinder of multilayer high pressure vessel , opening up a new method for welding clading stainless steel vessel
详细介绍了内筒为不锈钢的多层高压容器外u形坡口的单面焊接工艺，从而为不锈钢复合容器的焊接开辟了一条新途径。 |
| 10. | The analytical results shows that enlarging the longitudinal size of access hole effectively minimizes the potential of fracture at the groove welds between column and beam flange and the root of access hole
分析结果表明焊接孔长度的增大有效地降低了梁根部的对接焊缝和焊接孔切角端发生断裂的可能性，但过长的焊接孔长度将导致梁平面外稳定的丧失。 |
