摘要： An electron beam welding apparatus is provided with a magnetic shielding pipe for preventing electron beams emitted from being deflected by stray magnetic fields, and a removing device for removing metal deposit accumulated on a tip portion of the magnetic shielding pipe, which tip portion faces to a weld formed by welding of materials to be welded. The removing device is provided with at least a pair of shutters which move along a tip face of the tip portion to prevent the metal deposit from accumulating on the tip portion. The pair of shutters provides in their central portion a hole for passing electron beams therethrough when they are closed so that welding can continue irrespectively of the movement of the shutters.

摘要： Disclosed is a system for automatically successively inserting a plurality of U-shaped heat transfer tubes into holes of support members of an equipment such as a heat exchanger. The system has fixing means for removably fixing the support members such that the corresponding holes of the support members are axially aligned; gripping means adapted to pick up one of the heat transfer tubes and movable to bring the heat transfer tube toward the holes of supporting members; a positioning means disposed between the gripping means and the fixing means and adapted to hold the gripped heat transfer tube horizontally and to make the same align with the holes in the support members; and control means operatively connected to the gripping means and the positioning means so as to sequentially control the operation of both means in a predetermined sequence. The system operates as follows under the control of the control means. The gripping means grips the heat transfer tube and raises the same. The gripping means is then moved toward the support members while the positioning means supports the heat transfer tube. As the heat transfer tube is inserted deeper into the support members, the support of the tube by the positioning means is released. The gripping of the tube by the gripping means is released and the gripping means is then returned to the position for picking up the next tube, after the completion of the insertion of the heat transfer tube.

摘要： A method of welding opposite end surfaces of two titanium alloy parts kept in alignment by a high energy-density welding process such as electron beam welding, laser beam welding or TIG arc welding, characterized by closely interposing an insert member of either practically pure titanium or Ti-Al binary alloy containing up to 3 Wt % of Al. Owing to thorough alloying of the inserted titanium with the constituents of the fused base metal, the weld metal in a weld joint obtained by this method is sufficiently high in both strength and toughness. By an optional postwelding heat treatment, the strength of the weld metal can further be enhanced.
