- 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。
- 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。
- 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。
