The first layer welding was carried out in the melt-run welding, and the second and third layer were welded with filer wire. As a result, there were no weld defects in welded metal. The experimental results showed that the space GHTA welding process could apply to make the multi-layer butt welding, 形態: カラー図版あり, 共催: 日本学術会議, Physical characteristics: Original contains color illustrations, joint hosting: The Science Council of Japan, 資料番号: AA0064730044}, 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 = {真空環境での宇宙GHTA溶接法によるアルミニウム合金A2219の多層突合せ溶接実験}, volume = {26}, year = {2010} }
