FfPer iodicity of Transfer of Metal During Cathode Ray Welding"
Kiev, Avtomaticheskaya Svarka, No 8, Aug.73, pp 75-76.
Abstract: The following mechanism is proposed for metal transfer during
.-cathode-ray welding. The primary force acting on the liquid metal is the
recoil reaction arising upon partial evaporation of tho metal by the
electron beam. Since the recoil reaction is dirQcted perpendicular to the
surface of the melted metal, its.motion along the walls of the channel is
possible only when the surface is curvedl so that a sufficient tangential
component of recoil reaction arises. Curvature of the:surface of the
melted metal occurs as follows. - At a cei-tain film thickness of liquid metal
on the leading wall of the channel, waves: arise on the free surface of the
film, the amplitude of the waves increasing as film thickness increases. At
a certain critical thickness, the area of. the curved surface is sufficient
for the recoil reaction along the forward wall to cause movement of a given
ain mass of tile melted
curve into the depth of the channol, capturing the in,
metal located below. The amplitude of the wave increases, actelerating the

Abstraott A brief review is given of some reports nade at the Third Con-
ference on Electron-Beam Welding, 14-15 October 1971, sponsoxed by the Insi-itute
of Electric Welding imoni Ye, 0. Paton and the Moscow Power Engineering
Institute. Two hundred and fifteen delegaUs from more than 120 organizations
and industrial anterl=ises participated. Avadeniclan B. Yo. Paton opened
the Conference and reported on "The Curxent State and. Problems of Electron-
Beam Welding." He indicated experiences in developing the technology of
electron-bean welding of high-molting and vare metals. and high-strength and
beat- and corrosion-resistant alloya anitsteels. H. A, Ollslmnskiy at al.
reported on the welding technology, of metals, 6?,
