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 Tech Pub-278, paragraph 4.1. Evaluation
of our procedure qualification weldments is carried out by our
metallurgical staff at DCF's laboratory which is fully equipped to
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 Tech Pub-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 |
| Autogenous Tube to Tubesheet Welding |
|
|
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 Tech Pub-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.
