The invention discloses a hook loosening constraint welding method for LNG (liquefied natural gas) ship transverse bulkhead block carrying, which comprises the following steps: dividing a transverse bulkhead block into an upper bulkhead block and a lower bulkhead block, arranging laying rows on the upper bulkhead block and the lower bulkhead block, hoisting, performing constraint welding at the laying row positions, and then performing hook loosening. The row arrangement mode is adopted for constraint welding on the transverse bulkhead block, direct constraint welding on a framework is avoided, and the bulkhead precision problem caused by single-side welding shrinkage is effectively avoided; the carrying efficiency of the upper bay block is improved, and the construction cost of a shipyard is reduced.
本发明公开了一种LNG船横隔舱总段搭载的松钩约束焊方法,该方法通过将横隔舱总段分为上隔舱总段和下隔舱总段,并在上隔舱总段和下隔舱总段设置搁排后进行吊装,并在搁排位置处进行约束焊,再进行松钩。通过在横隔舱总段是上采用搁排的方式作为约束焊,避免了直接在构架上进行约束焊,有效避免了由于单侧焊接收缩导致的隔舱精度问题;提高了上隔舱总段搭载效率,降低了船厂的建造成本。
