Research Topics


The feasibility of developing a system to provide feedback to manual welders was demonstrated in Phase 1 of the Office of Naval Research STTR Project titled "Development of a Monitoring and Feedback Device to Improve Human Welding Productivity" (Contract No. N00014-00-M-0082). The system referred to as the "Manual ArcScan" measures welding parameters and provides real-time feedback to the welder regarding the acceptability of the parameters within pre-defined limits. The welder then uses the feedback to adjust the welding process. The "Manual ArcScan" can be used for both training welders and production applications. In Phase 2, a version of the Manual ArcScan that focuses on training will be developed and evaluated in shipyard and commercial training schools. DataWare is a Joint-Venture formed by AccuData, Inc. and WeldWare, Inc. AccuData and WeldWare have previously teamed to develop a monitoring system for robotic/mechanized welding applications, which is currently being marketed by AccuData. Other Phase 2 team members are Halter Marine, Newport News Shipbuilding, Bath Iron Works and Hobart Institute of Welding Technology. The objectives of this project are: (1) to develop and refine a real-time feedback system for training manual welding and (2) to evaluate the performance of the system in a shipyard.
