Proceedings of workshop held January 25-26, 2006, at the National Institute of Standards and Technology Boulder, Colorado


The National Institute of Standards and Technology (NIST) strongly supports the drive toward safer pipelines, and joined with the Pipeline and Hazardous Materials Safety Administration (PHMSA) to advance this goal. NIST in collaboration with PHMSA and several pipeline industry trade organizations, organized and executed the Advanced Welding and Joining Technical Workshop on January 25 and 26, 2006 workshop in Boulder, Colorado.

Assistance in organizing the workshop came from an 18-person steering committee selected to represent the different interests in the pipeline industry. This committee helped to prepare the agenda, identify speakers, organize the working groups, and promote attendance.

The workshop had 69 participants representing pipeline owners, technology developers, trade and standards organizations, and government agencies. The workshop structure included six keynote presentations to suggest some issues, five working groups (by topical area) to identify and rank the research needs, and summary presentations (back to the whole group) to compare results and comment on any overlaps or omissions.

The five working groups were:

• Weld Design in Emerging Materials,

• Construction,

• Weld Inspection and Assessment Methods,

• Weld Maintenance and Repair, and

• Joining Issues for Nonmetallic Materials
