    On a drilled deep hole occurred in the molten pool of the steady state bead during electron-beam welding, the quantities of some considerable forces in molten metal near it in welding are nearly estimated by simple calculation. Moreover the dynamic balancing of a drilled hole with these forces is discussed. As the result of this discussion, it is seen that the drilled hole is presumably reaching to the balancing state with these forces, and that is easily being kept in the molten pool as far as the bead in the steady state is continued.
    Moreover the collision and the length of the mean free path in the drilled hole between accelerated electron-beam and evaporated metal vapor are discussed, and some considerations for the relation between vapor pressure in the drilled hole and heating phenomena in metal by electronbeam are done.

    This study was conducted to investigate effects of alloying elements for mechanical properties of high strength basic weld deposit as-welded.
    High strength basic electrodes having the combination of alloying elements based on L8(27) orthogonal array table were made and these mechanical properties were measured.
    Analyzing these measured mechanical properties of test electrodes, the authors calculated Ceq for mechanical properties (yield point, tensile strength, elongation, impact value) of high strength basic weld deposit as-welded, and searched for equations between Ceq and values of the mechanical properties of weld deposits.
    The results obtained are as follows ;
    Ceq(Y.P)=C+0.08Si+0.17Mn+0.06Ni+0.11Cr+0.27Mo
    Ceq(T.S)=C+0.07Si+0.10Mn+0.04Ni+0.11Cr+0.14Mo
    Ceq(EL)=C+0×Si+0.07Mn+0.05Ni+0.05Cr+0.11Mo
    Ceq(E0)=C+0.13Si+0.01Mn+0.02Ni+0.20Cr+0.16Mo
    Ceq(E-40)=C+0.28Si-0.02Mn+0.04Ni+0.27Cr+0.13Mo
    Y.P(kg/mm2)=27.2+64.4Ceq(Y.P)
    T.S(kg/mm2)=26.6+135Ceq(T.S)
    EL(%)=37.6-43.1Ceq(EL)
    E0(kg-m/cm2)=32.7-62.6Ceq(E0)
    E-40(kg-m/cm2)=18.4-32.8Ceq(E-40)
