摘要： PROBLEM TO BE SOLVED: To provide a method by which a penetration bead formed on the inside of a U-shaped rib prevents stress concentration even when fillet welding is performed from one face on the outside of the U-shaped rib.SOLUTION: In a method for welding a butting part between a deck plate 10 and a flange 24 of the U-shaped rib constituting a vertical plate, when an edge, which contacts with the deck plate 10, of the flange 24 is welded from one side (outside) of the flange 24, a penetration bead is formed on the other side (inside) of the flange 24 through the edge part. In this process, a backing strip 1 is arranged in a region, which corresponds to a region welded from the outside of the flange 24, inside the flange 24 so as to be brought into contact with the deck plate 10 and the flange 24. In the backing strip 1, chamfering C is formed in a region corresponding to the penetration bead.

摘要： PROBLEM TO BE SOLVED: To provide a welding method by which a penetration bead for evading stress concentration is formed.SOLUTION: The length of dolly blocks 1 is made into a length which is divided the full length in the longitudinal direction y of a U-shaped rib 20 equally into n parts and n dolly blocks 1 and they are arranged in the longitudinal direction y of the U-shaped rib 20. When regions 1 are welded, the dolly blocks 1 which are arranged according to these regions 1 are pressed toward the U-shaped rib 20 so as to show with void arrows 1. When the welding of the regions 1 is finished, next, the welding of regions 2 is performed. Then, the dolly blocks 1 which are arranged according to the regions 2 are pressed toward the U-shaped rib 20 as shown by the void arrows 2. When the welding is moved from the regions 1 to the regions 2, the pressing of the dolly blocks 1 in the regions 1 are released. The procedure is repeated till the welding of regions n is finished, and the welding of the U-shaped rib 20 to a deck plate 10 is completed.
