A vacuum chamber for the GHTA welding test was placed in the cabin of the aircraft and the microgravity environment was produced by a parabolic flight of the aircraft. Butt welding and bead on plate welding of aluminum pipe were performed in the vacuum chamber under microgravity condition. Then we observed the welding phenomena and investigated macrostructures and mechanical properties of the butt weld joints. As a result, we showed the possibility of applying the GHTA welding process in space., 資料番号: AA0063349057}, pages = {213--216}, 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 = {模擬宇宙環境での宇宙GHTA溶接法によるアルミニウム管の突合せ溶接実験}, year = {2007} }
