抄録（英）
The authors develop the space Gas Hollow Tungsten Arc (GHTA) welding process for space applications since 1993. In order to utilize the space welding technology required for space developments, we are also developing the space Diode Laser (DL) welding which a welding principle differs from the space GHTA welding. The DL welding experiments in vacuum clarified the features of welding in vacuum and vapor deposition problems to optical devices in welding on stainless steel and aluminum alloy. Since the evaporating phenomena cause the damage on optical devices and space contamination, they should become serious problems in space welding applications. Therefore, we proposed the prevention technique of metal vapor deposition to optical devices by shielding gas.
