Relationship between weld quality and optical emissions in underwater Nd: YAG laser welding

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 underwater LBW. In this work, a sensing system contain...
