Friction Stir Welding Technology: Adapting NASA
WitrynaJeff Ding, an engineer at NASA's Marshall Space Flight Center, invented a new self-adjusting pin tool for a process known as friction stir welding. The technology is jointly licensed to MTS Systems Corporation, of Eden Prairie, Minnesota, and MCE Technologies, Inc., of Seattle, Washington. Witryna1 sty 2010 · Friction stir welding theme in AeroMat Conference & Exposition, ASM ... NASA started formulating a Process Specification of Friction Stir Welding at the beginning of 2000. The first version of it was issued in 2002 and was comprehensively reviewed and revised in 2007. Also in 2005, an AWS committee was set up to work … WitrynaNASA Marshall Space Flight Center (MSFC) developed Ultrasonic Stir Welding (USW) to join large pieces of very high-strength metals such as titanium and Inconel. USW, a solid-state weld process, improves current thermal stir welding processes by adding high-power ultrasonic (HPU) energy at 20 kHz frequency. moghwyns spear
