Welding

As a result of the nuclear submarine condenser program we currently maintain a weld/welder and weld data collection and record system that meet the requirements of MIL-STD-278, paragraph 4.1. Evaluation of our procedure qualification weldments is carried out by our metallurgical staff at DCF's laboratory which is fully equippedto accomplish complete metallurgical reviews. In addition DCF can provide extensive materials controls, including materials segregation and positive materials identification, as may be required by the most stringent of specifications.

DCF is qualified to ASME Section VIII Division I and MIL-STD-278. Our welding expertise includes:

• SMAW
• GMAW
• GTAW
• SAW
• Welding to 8" thick
• Dissimilar Materials Welding
• Clad Materials
• Tube to Tube Sheet
• Fully Automatic Pipe Welding
• Twin Wire Non-Ferrous SAW
• Corrosion Resistant Overlays

We have an established experimental welding and training laboratory which is equipped to train and test our welders and to permit fabrication of ASME and MIL-STD-248 procedure qualification samples. The Welding Technician, designated as one of the participants in this program, currently trains new welders in new processes and audits their continuing capabilities.
