 note = {As a feasible welding method in space, the Space GHTA (Gas Hollow Tungsten Arc) welding method has been proposed in the previous papers. The Space GHTA welding using the high frequency power source may have an electromagnetic noise problems of computer equipment placed on the ISS. In this report, a Space GHTA welding experiment using the DC high voltage power source was carried out under the ISS orbital pressure 10(exp -5) Pa. The results are summarized as follows; 1) It is made clear that there is a shifting phenomenon in which a glow or an arc is formed after the spark at starting phenomenon of the Space GHTA welding in high vacuum condition, and the feature of those starting phenomenon are demonstrated. 2) The arc ignition unit of GHTA with DC high voltage power source can be used in the ISS orbital pressure. 3) The arc formation ratio increases with increasing the starting voltage, but the starting current has no effect on the arc formation ratio. 4) The arc formation ratio increases in order of arc operating gas Ne, Ar and Kr under the same starting conditions., 資料番号: AA0045438034},
