Objective:

This project will evaluate enhanced primers that can be used during weld operations with no impact to schedule or weld quality.

Summary:

Welding and coating application in shipyards are performed by different groups with long intervals in between work evolutions. Welding is often performed long after coating operations have been completed and touch-ups are later required. The coating application teams must be made aware of future weld sites and mask off these areas for future work. This leaves bare steel exposed to the elements to corrode and potentially result in material loss prior to weld operations. In such instances, extra time must be taken by the welding trades to properly prepare the surfaces to be welded. Use of weld through primers is found in other industries with relative success. This project seeks to investigate the current field of weldable primers and their use within shipyard operations.

Key Deliverables / Benefits:

  • The overall shipbuilding process will improve with quicker turnaround times. This will allow for more time to be spent in other stages and overall better throughput at shipyards
  • Reduction in time spent masking off areas to be welded later in production cycle
  • Reduction in corrosion and potential material loss at weld sites with uncoated steel allowed to rust between work evolutions
