Abstract

Numerical analysis is done to study on effect of welding speed on evaluation of welding distortion by welding heat input. It is clarified that angular distortion, caused by inhomogeneous distribution of residual inherent strain, is not always evaluated by only welding heat input and influenced by characteristics of temperature distribution during welding.
