The welding part 7 on the outer periphery of the joint surface with the welding part 7 is vacuum-tightly welded by TI'G welding or the like.
また、囲い体６と本体部４ａはあらかじめ、溶接部８で
真空タイトに溶接されている。Further, the enclosure body 6 and the main body portion 4a are vacuum-tightly welded in advance at a welding portion 8.
最後にフランジ４ｆと４ｇは接合面４ｅの外周の溶接部
９でＴＩＧ溶接などで真空タイとに溶接される。Finally, the flanges 4f and 4g are welded to a vacuum tie by TIG welding or the like at a welding portion 9 on the outer periphery of the joint surface 4e.
保護管４の真空タイトは、フランジ４ｆと４ｇの溶接部
９、及び囲い体６の溶接部７，８によって保たれ、結合
の機械的強度はボルト５が受けもつ構造となっている。The vacuum tightness of the protective tube 4 is maintained by the welded portions 9 of the flanges 4f and 4g, and the welded portions 7 and 8 of the enclosure 6, and the mechanical strength of the connection is provided by the bolts 5.
結合後の真空タイト溶接は突出した外周の部分で行なわ
れるため、内部に与える熱的な影響は少なく、内部のコ
イル１の絶縁には支障はない。Since the vacuum tight welding after joining is performed on the protruding outer periphery, there is little thermal influence on the inside, and there is no problem with the insulation of the internal coil 1.

かつ、突出した外周端で行なっているので、コイル絶縁
に及ぼす影響は極めて少ない。As described above, according to the present invention, the longitudinally divided protection tubes are joined together with bolts to provide mechanical strength, so that the joining surface and the bolt head side can only be vacuum-tight. Welding can be used, and the weld overlay can be small,
Moreover, since this is done at the protruding outer peripheral end, the effect on coil insulation is extremely small.
また、溶接による保護管の熱変形がほとんどなく、高い
精度の真空タイトのコイルの保護装置が得られる。Further, there is almost no thermal deformation of the protection tube due to welding, and a highly accurate vacuum-tight coil protection device can be obtained.
