We have also been developing the space Diode Laser (DL) welding which its welding principle differs from the space GHTA welding. The metal vapor deposition on optical devices caused in the DL welding experiments in a vacuum can be prevented by using the shielding gas. We performed the butt welding experiments with SUS304 stainless steel and A2014-T6 aluminum alloy at the International Space Station (ISS) orbital pressure. The mechanical properties of butt welding joints, and the effect of root gap and filler metal addition on weld metal shape were clarified., 資料番号: AA0063349056}, pages = {209--212}, 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 = {高真空環境下における宇宙半導体レーザ溶接実験}, year = {2007} }
