Qualifications
As a general rule, WFSI’s weld procedures are qualified to these three specifications:
- ASME Section IX
- AWS D1.1 (Steel), D1.2 (aluminum), D1.6 (stainless steel), D14.1 (material handling) & D17.1
- NAVSEA S9074-AQ-GIB-010/248 (MIL-STD-248) and S9074-AQ-GIB-010/278 (MIL-STD-278)
At the same time, many procedures conform to customer-specific and other agency-required standards such as:
- NACE MR01-75/ISO 15156-X
- DNV (Off-Shore Standard) and DNV-OS-E101 (Drill Plant)
- API Specification 6A/16A ASME B31.1 (power piping) and
- ASME B31.3 (process piping)
- Ground Combat Vehicle Welding Code (aluminum 12472301) and (steel 12479550)
The previous lists were not intended to be all-inclusive. Our highly skilled welding operators are cross-trained and certified for a wide range of welding codes and processes. Please contact us if your specific welding code or process is not listed.
