Objective:
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.
