摘要： PURPOSE:To maintain a molten metal in a molten state for a long period in a high vacuum in an electron beam melting device by providing a heater for heating in the mid-way of the falling molten metal. CONSTITUTION:A raw material 1 for melting is melted by an electron gun 2 and a liquid drop 3 is formed. The drop 3 is held for a prescribed period in a vacuum by an induction coil 4 in the mid-way of falling, by which the effect of refining the metal is provided. The liquid drops 3 are continuously supplied during the time when said drops are held in the coil 4. The drops fall by gravity when the weight which can not hold by an electromagnetic field is attained. The falling drops enter the inside of a copper mold 7. An inlet and outlet 8 for cooling water is provided to the mold 7. The cooling water 9 flows from the lower part to the upper part of the mold 7. The liquid drops falling from the inside of the coil 4 form a molten metal part 6. An electron beam is irradiated for a prescribed period from the gun 2 for heating to maintain the molten state. A solidified part 10 increases toward the lower part of the mold, thus forming an ingot.
摘要翻译：目的：在电子束熔化装置的高真空中长时间保持熔融状态的熔融金属，通过在熔融金属的中途提供加热器进行加热。构成：熔融用原料1由电子枪2熔化，形成液滴3。在真空中通过感应线圈4将液滴3保持在规定的时间段内，从而提供金属的精炼效果。液滴3在液滴保持在线圈4的时间内连续供给。当不能用电磁场保持的重量达到时，液滴因重力而下降。落下的液滴进入铜模7的内部。用于冷却水的入口和出口8被提供给模具7.冷却水9从模具7的下部流向上部。线圈4的内部形成熔融金属部分6.电子束从枪2照射规定时间以进行加热以保持熔融状态。固化部分10朝向模具的下部增加，从而形成锭。

摘要： PURPOSE:To prevent decrease in characteristic owing to a change in the alloy compsn. of a weld zone by disposing a metal consisting of the same alloy components and having different compsn. ratios between the weld zone of a coated pipe and the weld zone of an end plug and welding said pipe and plug. CONSTITUTION:If an end plug 3 consisting of a zirconium alloy is welded to a coated pipe 1 formed by binding metallurgically a pure zirconium barrier 2 to the inside surface of a zirconium alloy pipe, the alloy components in the melted and solidified part changes and therefore a ring 4 consisting of the alloy composed of the same components as the components of the pipe 1 and having different compsn. ratios is fitted between the pipe 1 and the plug 3 and TIG welding is accomplished in gaseous helium maintained under 1atm.
