During underwater laser beam welding (LBW), the welding quality is severely influenced by the shielding condition of the local dry cavity. In this paper, the stability of the local dry cavity and the effect of shielding condition on the weld quality

In underwater laser welding (LBW), the weld quality is very dependent on the shielding conditions of the local dry cavity when other welding parameters are fixed. Thus, diagnosing the stability of the local dry cavity is the key to monitoring of unde

Wine-cup weld bead geometry with excessive wide bead surface is apt to form for high-power high-brightness laser welding in range of low welding speeds (lower than 1 m/min), as a result, the decrease in welding speed induces considerable increase in

In underwater laser beam welding, the shielding condition of the local dry cavity is one of the key factors affecting the weld quality. The variation in the weld bead formation and mechanical properties of the welded joint under various shielding con
