Description: NASAï¿½s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology.ï¿½ License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.ï¿½ï¿½NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: NASA Goddard Space Flight Center invites companies to license this dead-end welding device for use in the welding of tubing.ï¿½ This technology solves the problem of unacceptable welds in dead-end configurations.ï¿½ This technology produces consistently high quality dead-end welds in a fraction of the time required when using conventional welding techniques. The welding of tubing presents specific challenges, particularly in dead-end configurations.ï¿½ In order to meet welding standards, typical tubal welding requires an internal gas flow-through purge with a restrictor on the end of the purge component.ï¿½ The restrictor controls the internal pressure to prevent the weld from falling in or blowing out.ï¿½ When confronted with a tubes closed end (i.e., a dead-end configuration), however, the gas purge has no exit. The increase in pressure within the component produces a faulty weld.ï¿½ Using conventional techniques, the only way to get an acceptable weld in a dead-end configuration is to do numerous practice welds before welding the actual component. By controlling the internal pressure of the gas purge during welding, this new technology produces consistently reliable and high quality welds with minimal setup time. The unique device is composed of a vent tube with vent holes, a gas supply, a flexible Teflon tube connected to a flow meter, and a T fitting (see diagram).ï¿½ Gas flows from the gas supply to the T fitting and then flows through the tube to the dead-end weld configuration assembly.ï¿½ As the pressure within the tube increases, the flow of gas exits through holes in the vent tube and escapes through the Teflon tube.ï¿½ The flow meter, which is attached to the Teflon tube and preset to a specific value based on the tube size, regulates the pressure along the Teflon tubing. This technology has been proven to be highly successful with many dead-end weld configurations as well as with various alloys.ï¿½ It produces a consistently higher quality dead-end weld than conventional welding techniques and does so in a fraction of the time.ï¿½ Its monitoring capability enables precision control in any dead-end configuration.ï¿½ It is a reliable and very low maintenance device that presents no safety concerns. To express interest in this opportunity, please submit a license application through NASAï¿½s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/GSC-TOPS-50 If you have any questions, please contact NASA Goddard Space Flight Centerï¿½s Technology Transfer Office at techtransfer@gsfc.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information.ï¿½ For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ These responses are provided to members of NASAï¿½s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.ï¿½ï¿½No follow-on procurement is expected to result from responses to this Notice.
