- Abstract
- To estimate welding deformation for large steel structures, either experiment result with small specimen or analysis result of FEM with small numerical model in used. Consequently, it is important to decide the welding length of specimen and numerical model not to have an effect on welding deformation for accurate estimation of whole welding deformation.
This study experimentally clarifies the effect of welding length on angular distortion due to welding by varying welding length of specimens, but fixing width and thickness of specimens on V-groove butt welding, fillet welding and bead on plate welding. As a result, the critical welding length on fillet welding and on bead on plate welding is over 500㎜ and on V-groove butt welding is over 1,000㎜.
