Abstract

The reducing effect of the angular distortion in Tee type full penetrated welded joint fabricated by the laser-arc hybrid welding was investigated. The Angular distortion caused by the laser-arc hybrid welding were measured and compared with one caused by the CO2 gas shielded arc welding. As a result, the amount of angular distortion by the laser-arc hybrid welding was the same level as one in case of forming the leg size of F1 grade regulated by Common Structural Rules for Bulk Carriers (CSR-B) by applying arc welding. In addition, numerical analysis of the welding deformation was carried out by the thermal elastic-plastic finite element analysis and these results were generally consistent with the measured results. Moreover the effect on FE result of the penetrated shape was discussed.
