It was also clarified by from the experiments using a high-voltage DC device for arc start at the ISS orbital pressure that there is a shifting phenomenon in which a spark discharge shifts to either a glow discharge or an arc discharge when starting the arc. Therefore, in this report, arc starting experiments of the space GHTA welding using a touch start technique for arc start were carried at the ISS orbital pressure, 10(sup -5) Pa.. As a result, the space GHTA welding using a touch start technique can be used for arc initiation when welding at the ISS orbital pressure., 形態: カラー図版あり, 共催: 日本学術会議, Physical characteristics: Original contains color illustrations, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113033}, 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)}, title = {宇宙GHTA溶接法のタッチスタート方式によるアーク起動実験}, volume = {22}, year = {2006} }
