 note = {Aluminum alloys that have high specific strengths have been widely used in constructing various space structures including the International Space Station (ISS) and launch vehicles. Considering space applications, a series of welding experiments were performed in vacuum on an aluminum alloy using the GHTA (Gas Hollow Tungsten Arc) welding processes under d.c., a.c., and d.c.-pulsed conditions. Results observed in the GHTA welding experiments performed in vacuum can be summarized as follows: 1) When GHTA welding was performed using a commercial a.c. welding machine, the arc discharge did not occur during the electrode positive polarity of alternating current. As a result, it was not possible to remove oxide films from the specimen surface resulting in the cleaning action. 2) During the d.c.-pulsed GHTA process, it was possible to mechanically shatter and remove the oxide films covering the molten pool by the impact of the arc force., 資料番号: AA0046917088},
