Research & Development: Meetings - Workshops

R&D Menu

The Advanced Welding and Joining Workshop was held in Boulder, CO on January 25 - 26, 2006. The 1.5 day event included approximately 75 representatives from Federal, State and international government agencies, public representatives, research funding organizations, standards organizations, and pipeline operators from the U.S. and Canada.

The purpose of this workshop was to collaboratively identify mutual welding and joining goals for government and industry to address along with the regulatory, standards and technology actions required to achieve them. Several critical gaps in technology, standards and knowledge were identified during five parallel breakout sessions.
