Abstract
PURPOSE:To obtain a highy conductive electromagnetic shield of a superconductive rotor by forming first cylinder of conductive material and second cylinder of reinforcing material by machining and butt welding and shrinkage fitting or explosion conneting the cylinders. CONSTITUTION:Conductive material such as oxygen free copper of the like is bent to form a semi-circular member. The members are connected by an electron beam welding as a butt welding to thereby form a first cylinder 22. In order to reinforce the first cylinder, reinforcing material is similarly formed from metal having higher strength than the first cylinder such as, for example, nonmagnetic steel to form a second cylinder 21' by welding at 25. Then, the second cylinder 21' of smaller diameter is inserted into the first cylinder 22, and shrinkage fitted or explosion connected. In some cases, large-diameter second 21 is formed by reinforcing material' the composite cylinder thus formed is inserted into the second cylinder 21 to explosion connect them from outside of the cylinder 21 to thereby obtain electromagnetic shield of tripple construction.
