FIELD: process engineering.
SUBSTANCE: invention relates to production of large-sized structures of molybdenum and its alloys, for example, at welding of shells of high-temperature gas-static muffle shields. Structure sheet edges are trimmed and formed. T-like copper insert is fitted between trimmed edges to the clearance there between to comply with leg depth. Trimmed edges are welded together by electron beam at incomplete penetration over the height. Welding is performed by repeated heating of non-penetrated trimmed edges with filling of said clearance with said copper insert.
EFFECT: decreased brittleness of the structure.
