Evaluation of the Universal Hand Tool for Metals Processing in SpaceThe Paton Welding Institute, Kiev, Ukraine, has developed the Universal Hand Tool for processing Metals in the space environment. The Universal is a hand held, 1 kilowatt electron beam welding tool designed to accept attachments to enable welding with and without filler wire, cutting, and coating by vapor deposition. The Marshall Space Flight Center, together with the Paton Institute, designed and developed the International Space Welding Experiment (ISWE) to demonstrate the Universal Welding System during an extravehicular activity on STS-87. ISWE was subsequently demanifested and has not been remanifested at this time. This paper describes the science objectives of ISWE, the safety hazards associated with manual welding in space and the associated resolutions, and the results of ground based development efforts. The Universal was adequate for processing the samples planned for ISWE and was successfully modified to meet shuttle payload constraints. Sample cleanliness and operator training proved to be the primary drivers for the quality of the processed samples.
