The objective of this proposed study is to develop a robust underwater "wet" welding process using the "SmartShroud", which is an intelligent system developed under multiphase research projects sponsored by the Ohio Sea Grant College Program (OSGCP) over the past four years. It integrates an adaptive "momentum barrier" mechanism (which effectively maintains a gaseous arc atmosphere in various welding joint conditions) into two other subsystems: the smart arc bubble status monitoring/control, and the intelligent joint tracking/operation guidance subsystem. This system will improve the arc performance in underwater welding and slow weldment cooling rates, hence improving microstructures and weld quality. It will also assist the diver performing underwater welding operations in an environment of difficulty to observe welding conditions directly. The integrated welding system will be able to produce air-quality "wet" welds in practical industrial applications. It will provide the diving contractor industry with an underwater "wet" welding technique for permanent offshore structure repairs. It will take two years to accomplish the proposed objectives.
