Claims (1)

전자방사물질과 다공질 내열성 소결체로 구성한 펠렛트(1A)가 양단이 개방되고 내열성 금속으로 된 음극링(2A) 내로 결합되어져 있는 음극기체(A)를 구비한 함침형 음극의 제조방법에 있어서, 내열성 금속의 파이프상 금속원통제(A1)내에 장측으로 길이화된 봉상소결체(A2)를 밀착삽입시킨 후 급속원통체(A1)와 봉상소결체(A2)를 레이져 라인 용접(d)에 의해 장측으로 연속고정부착한 후 소정크기의 음극기체(A)로 재단하는 공정을 포함하는 함침형 음극 제조방법.A method for producing an impregnated cathode comprising a cathode gas (A) in which a pellet (1A) composed of an electron-spinning material and a porous heat-resistant sintered body is open at both ends and joined into a cathode ring (2A) made of a heat-resistant metal. After inserting the rod-shaped sintered body A2 lengthened to the long side in the metal pipe-like metallic cylinder A1, the rapid cylindrical body A1 and the rod-shaped sintered body A2 are continuous to the long side by laser line welding d. Impregnated cathode manufacturing method comprising the step of cutting to a predetermined size negative electrode gas (A) after fixed attachment. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
