NSRP ASE Investment: $50K
In an effort to reduce the cost of fabricating Navy surface combatant ship piping systems, this project focused on implementing welding methods using recent advancements in Gas Metal Arc Welding-Pulsed Arc equipment technology. This process allows for single pass socket welds to be used in lieu of two-layer welds, while maintaining required weld quality with an average time decrease of 86.9%. A Supervisor of Shipbuilding, Conversion & Repair (SUPSHIP) approved welder training package was developed to provide specific weld parameters and techniques to allow consistent implementation within the Navy shipbuilding industry.
