概要

Recent welding sequences are studied on the erection butt joint of ship-hull-block, in which plates and stiffeners are tack-welded at the same time. Restraint intensity and residual stress are measured with block butt joints fabricated by the recent welding sequences and compared with the value of calculation by F.E.M., calculation of elastic dynamic, and measurement on actual ship by other researchers. The conclusions are as follows : (1) No cold cracks due to restraint occur under the maximum restraint condition or block butt joint which has a tack welding at the weld deferment.(2) The residual stress distribution of welded joint of ship-hull-block shows no remarkable differences due to the welding scquences.
