- BMT Fleet Technology
- General Dynamics NASSCO
NSRP ASE Investment: $99K
This project sought to obtain qualification by the Naval Sea Systems Command and the American Bureau of Shipping for welding procedures developed under previous NSRP work that resulted in productivity enhancements as high as 1200% and cost reductions approaching 65%. The project focused on HSLA-65 and DH36 steels, using variable balance submerged arc welding and metal cored electrode technologies. As a result of this project, the welding procedures were qualified under the requirements of NAVSEA Technical Publication 248.
