摘要： A heating apparatus (10) and method for pre-weld heat treating, welding and post-weld heat treating a superalloy article in a single enclosure (12) while avoiding oxidation of the article. The enclosure (12) is preferably equipped with a one-way valve (32) that permits the escape of gases, but otherwise seals the enclosure (12) to prevent the ingress of air during welding and heat treatment as a result of thermal gradients induced when the article is inductively heated. To provide access to the article and a device (20) used to weld the article, the enclosure (12) is equipped with gloves (30) by which the welding device (20) and the article can be manipulated while a nonreactive atmosphere is fully maintained within the enclosure (12) and the article is inductively heating.

摘要： The invention relates to nuclear power and can be used in the manufacture of fuel elements for nuclear reactors. Embodiments of a welded joint between a fuel element casing and a plug comprised of high-chromium steel are proposed, providing for increased durability of the sealing of nuclear reactor fuel elements as a result of the formation of a high quality welded joint between the casing and the plug without the need for subsequent heat treatment of the weld seam, which simplifies the manufacturing process. This is achieved through the formation of a ferrite phase in the metal of the seam by adjusting the structure of a joint between the casing and the plug of ferrite-martensite and ferrite steels in various combinations and by keeping the necessary ranges of the size ratios to ensure the formation of the aforesaid phase.
