Paper Title:
Optimization of Laser-Arc Interspacing Distance during CO2 Laser-GMA Hybrid Welding by Using High-Speed Imaging
  Abstract

Laser welding has not easily been adopted in shipbuilding industry because of its poor gap bridging ability. Recently, laser-GMA hybrid welding process showed possibility to overcome the tight gap tolerance with improved productivity. The laser-arc hybrid welding process is inherently complex because it has three kinds of process parameters: arc welding, laser welding and hybrid welding parameters. In this study, welding phenomena were investigated to optimize the hybrid process parameter; interspacing distance between laser and arc. The bead surface and cross-sectional shapes were evaluated, and weld pool shape and droplet transfer were monitored by high speed camera to clarify welding phenomena.
