摘要： A method whereby defect-free welds can be produced in joining metallic members of dissimilar materials by electron-beam welding. The method consists in inserting one of the metallic members in openings formed in a metallic plate of the same material as the other metallic member and welding one metallic member to the metallic plate by providing a weld metal, providing by overlay welding on the weld metal a padding metal of a material substantially similar to that of the other metallic member but lower in oxygen content, effecting machining of the outer surface of the padding metal to form a faying surface, and joining by electron beam welding the faying surface of the padding metal to a faying surface formed on the other metallic member whereby the faying surfaces can be rigidly welded.

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.

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.
