- 論文の詳細を見る
An experimental technique utilizing a cine-fluoroscopy and a metal tracer was developed to continually monitor the electron beam welding process. This technique made it possible to observe the dynamic nature of the beam hole more directly and more clearly than some others. Using aluminum alloys as the parent metal, some phenomena related to the beam-metal interactions such as the big wall-fluctuation at the back side of the beam hole ("wall-cave" and "wall-knob"), the formation of root porosity due to the arched curvature of the beam hole, the behaviours of spiking concerned with the hole shape, and in part the rapid movement of the molten metal were apparently revealed.
