Abstract
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.
