In-Situ Hydrogen Analysis in Weldments: Novel NDE for Weld Inspection

In this program, the Colorado School of Mines and the National Institute of Standards and Technology - Boulder will collaborate in the development of non-destructive technology for weld inspection, assessment, and repair in high strength pipeline steels and their weldments. Advanced sensors will allow the pipe integrity to be frequently or continuously monitored to assure pipeline safety and environmental protection. The research would be further advanced by the characterization of hydrogen in pipeline steel weldments. The characterization of hydrogen content and behavior in high strength steel weldments is timely and important with the introduction of new higher strength steels (e.g. X100, which have higher susceptibility to hydrogen damage) in the pipeline industry.
