We carried out the bead-on-plate and but weld experiments on A2014 aluminum alloy using the DL welding process in vacuum. It clear that there is a spattering phenomenon peculiar to a vacuum environment that the high-temperature fine particles scatter from the surface during the butt and bead-on-plate weld, and the A2014 aluminum alloy butt weld joint welded with wire feed has the enough joint strength., 形態: カラー図版あり, 資料番号: AA0064297100}, 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 = {真空中でのアルミニウム合金の半導体レーザ溶接現象}, volume = {25}, year = {2009} }
