METHOD FOR MANUFACTURING WELDED THIN-WALLED CONICAL PART CONSISTING OF SHELL AND BODY PARTS WELDED TO IT ALONG ANNULAR JOINTS Russian patent published in 2021 - IPC B23K31/02 B23K37/04 

FIELD: welding production.

SUBSTANCE: invention relates to the field of welding production of thin-walled conical parts, consisting of shells and body parts, welded together at annular joints. The method includes manufacturing a shell and body parts welded to it, for example bottoms, flanges or bushings, assembling the parts to be welded on one-piece backing rings and welding circular joints. The body parts from the side of the annular joints are made with larger diameters than the diameter of the butted shell, without changing the specified thickness of the welded edges in the places of the annular joints, while the diameter of the body parts from the side of the annular joints is determined according to the corresponding formula, taking into account the shrinkage of a particular material, the welding method and the taper angle.

EFFECT: use of the invention makes it possible to reduce the complexity of manufacturing, as well as to improve the quality and accuracy of the geometric parameters of the finished product.
