HOUSTON-- A new service addresses the stringent requirements of weld root profiles in offshore projects, according to a presentation at the Deep Offshore Technology conference.
In a paper on internal weld scanning, specialists from Optical Metrology Services, Dr. Tim Clarke and Dr. Richard Gooch, described how the new tool is applied in different settings.

There are a number of reasons why scanning the weld is required, the authors say, with a case-by-case overview of these scenarios:
* Internal pipe coatings checks
* Before and after coating of pipes
* Prolonging the fatigue life of a pipeline
* Checking critical joints are welded correctly
* Quality control of spiral weld
* Clad welding of a pipe.

In addition, the presentation provided an overview of the tools available to address all pipe sizes from about 150 mm to 1,000 mm (6 in to 39 in). The presentation of specific examples illustrated how the new tools can be used in various pipe sizes to provide vital information to increase efficiency of pipe laying, improve weld quality, assess corrosion resistance, and monitor manufacturing processes.
