What No Cofferdam?- Class approved Underwater Wet Welded Groove Welds

DIGITAL IMAGESubsea Global Solutions is proud to announce that it has recently qualified more underwater wet welding procedures.  Subsea Global Solutions has qualified procedures for groove welds, meeting the Class A requirements of the American Welding Societies specification AWS D3.6M:3010 – Underwater Welding Code. The welding of the test plates was witnessed by Lloyd’s Register, who also issued the certificates approving the procedures. At the same time Subsea Global Solutions qualified 8 welder divers to the groove welding procedures.  Subsea Global Solutions continues to lead the way in the industry by qualifying it’s personnel and processes to these stringent wet welding requirements.  These additional procedures are added to our already existing Class approved Class “A” fillet wet welding procedures.
