Method for attaching ring, ring and system

Abstract

A method for attaching a ring to a borehole tool including locating the ring on the tool, running a weld bead around the ring without alloying the ring to another parent material, the weld causing contraction in a circumferential dimension of the ring. A method for producing a ring for a downhole tool including forming the ring with a weld groove at an outside surface of the ring. A ring for a downhole tool including a ring body, a weld groove formed in an outside surface of the ring. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a ring disposed on the string.
