In order to apply the welding technologies to space environment, welding experiments on the aluminum alloy have been conducted in vacuum using the GHTA (Gas Hollow Tungsten Arc) welding processes. In these experiments, removal mechanism of aluminum-oxide film and the melting phenomena of a filler wire were investigated, in which a high-speed video camera and a SEM (Scanning Electron Microscope) were employed. The experiments under the various welding conditions in vacuum were performed., 資料番号: AA0048095014}, pages = {59--62}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {宇宙GHTA溶接法によるアルミニウム合金の溶接現象と酸化膜除去機構}, year = {2005} }
