초록

Hybrid laser-rotating arc welding (HLRAW) process was designed by combining the laser beam welding (LBW) process with the rotating gas metal arc welding (RGMAW) process. In this study, comparing with conventional HLAW, weld bead characteristics as a function of the various process parameters were evaluated for HLRAW. Moreover, welding phenomena were analyzed by high speed monitoring with laser illumination. The arc rotation enhances the weld pool motion, therefore it reduces the undercut formation which is one of most critical weld defects in the conventional laser-arc hybrid welding.
