Abstract

Underwater laser beam welding was put forward to meet repairing of irradiated components and structures used in nuclear-power plant. Due to the interaction between laser beam and water, the laser-induced plasma or plume is rather complex than in atmosphere. This paper tries to monitor the stability of welding process by detecting the plume in underwater laser beam welding.
