3.3.4.1 根据表11.3.3,复板与外板的连接应采取连续角焊,舭龙骨与复板的连接采取轻连续角焊。
3.3.4.2 舭龙骨和复板的对接焊缝应彼此远离,与外板的对接缝也应错开。通常,复板位置的外
板对接缝应磨平,舭龙骨位置的复板对接缝也应磨平。应避免复板对接焊缝与外板的对接焊缝直接连
接和舭龙骨对接焊缝与复板的对接焊缝直接连接。
3.3.4.3 舭龙骨对接焊缝通常不采用扇形孔和切口。在舭龙骨对接焊缝上的止裂孔应尽可能靠近
复板,洞孔应大于对接焊缝的宽度,且直径最小为25mm,如图11.3.4所示。如对接焊缝已采用无损检
测,则不必开止裂孔。

Butt welds in the bilge keel and doubler are to be full penetration and are to be kept clear of master
erection butts. In general, shell butts are to be flush in way of the doubler, and doubler butts are to be flush
in way of the bilge keel. In general, scallops and cutouts are not to be used. Where desired, a drilled crack
