Some fundamental researchs were carried out on the dynamic aspects of weld molten metal in electron beam welding. That is, the authors observed the shape of the piercing hole during welding by means of a pin-hole X-ray camera, exposed solidification interface by means of the instantaneous extrusion method, observed the flow of weld molten metal by means of insertion of dissimilar metals, studied dynamic behaviors in the surface of weld molten metal using a high speed picture and also studied the relations between the surface swellings of molten metal and the repetitions of spiking and weld bead ripple. From the results obtained in these experiments, authors showed the dynamic behaviors of molten metal during electron beam welding to a schematic diagram and discussed its welding mechanism.
