METHOD FOR REPAIRING DENTS IN VESSELS Russian patent published in 2018 - IPC B23P6/00 

FIELD: machine engineering.

SUBSTANCE: method of repairing dents in a vessel body comprises producing a patch with size and shape corresponding to the damaged portion, placing the patch on the portion under repair and welding the patch by the main weld along the perimeter to the vessel. The patch is placed in the dent, concentric to the outer surface of the body, beyond the radius transition from the vessel body to the dent at a distance equal to the thickness of patch from its inner surface to radius transition, and a bevel is made at the edge of the patch at an angle of 55±5° to the plane of the dent along the contour of the patch. At the point of transition from the main seam to the radius on the dent, an additional weld seam is applied and smooth transition from the seam to the radius of the dent is made by machining.

EFFECT: simplification of the method for repair and improvement of strength of the repair joint of the vessel body wall with the dent.
