Conduit Purging Device and Method

NASA’s Goddard Space Flight Center invites companies to license this dead-end welding device for use in the welding of tubing. This technology solves the problem of unacceptable welds in dead-end configurations. The technique has been proven to be highly successful with many dead-end weld configurations, as well as with various alloys. It produces a consistently higher-quality dead-end weld than conventional welding techniques, and does so in a fraction of the time. Its monitoring capability enables precision control in any deadend configuration. It is a reliable and very low-maintenance device that presents no safety concerns.
