The invention discloses a light subbulkhead crack repairing method. The method comprises the steps of confirming that a crack appears on a non-watertight light subbulkhead which does not participate in total strength and only one crack with the width not greater than 5mm appears on the bulkhead, and measuring the positioning and setting size of the crack; drilling crack arrest holes in two ends of the crack to prevent the crack from continuing to expand, and releasing the tip stress of the crack; determining the size and material of a covering plate, and selecting a welding rod; and welding the covering plate and the original bulkhead plate. According to the light subbulkhead crack repairing method, the influence on peripheral equipment, outfitting parts and the like can be reduced while the local strength of the light subbulkhead structure is guaranteed, so that the construction period can be shortened, the construction difficulty can be reduced, and meanwhile the navigation rate of a ship can be increased.

    本发明公开了一种轻次舱壁裂纹修复方法,包括以下步骤:确认裂纹出现在未参与总强度的非水密轻次舱壁上,且舱壁上仅出现一条宽度不大于5毫米的裂纹,测量裂纹的定位定形尺寸;在裂纹的两端打止裂孔以防止裂纹继续扩展,同时释放裂纹尖端应力;确定覆板的尺寸及材料,并选取焊条;焊接覆板与原舱壁板。本发明提出的轻次舱壁裂纹修复方法,在保证轻次舱壁结构局部强度的同时,可减少对周边设备、舾装件等产生影响,从而能缩短施工周期,降低施工难度,同时可提高舰船的在航率。
