Abstract

Recently, it has become necessary to control or reduce weld distortion, which has a negative influence on structural integrity, without loss of manufacturing efficiency. Some studies on the fundamental characteristics of weld distortion and its control or reduction have been conducted. However, the results cannot be applied to all welding processes because such processes are becoming more diversified. For this reason, to understand the fundamental characteristics of weld distortion based on the welding conditions, the heat transport phenomenon in arc physics must be investigated. In this study, an experiment and numerical simulations are conducted to investigate the link between arc physics and weld distortion. As a result, the relation between weld distortion and the heat transport phenomenon is further clarified.
