Abstract
An assembly is provided for a turbine engine. This assembly includes a carrier, a control ring and a bladed outer air seal mounted to the carrier. The carrier extends circumferentially around an axis. The carrier includes an annular cavity, a first section and a second section. The annular cavity is formed within the carrier by the first section and the second section. The first section is welded and/or brazed to the second section at a sealed full-hoop bond joint. The first section is further connected to the second section at a second sealed full-hoop joint. The control ring extends circumferentially around the axis within the annular cavity.

An assembly for a turbine engine, comprising:
- a carrier extending circumferentially around an axis, the carrier including a cavity, a first section and a second section, the cavity formed within the carrier by the first section and the second section, the first section welded and/or brazed to the second section at a sealed full-hoop bond joint, and the first section attached to the second section at an interference fit connection between the first section and the second section;
- and
- a control ring extending circumferentially around the axis within the cavity.
A method of manufacture, comprising:
- arranging a control ring in a channel of a carrier first section;
- arranging a carrier second section with the carrier first section, the carrier second section axially and radially engaging the carrier first section so as to self-fixture the carrier first section with the carrier second section for subsequent welding and/or brazing;
- and
- welding and/or brazing the carrier second section to the carrier first section to provide a sealed full-hoop bond joint between the carrier second section and the carrier first section, wherein the control ring extends circumferentially around an axis within an annular cavity of a carrier, and the cavity is formed within the carrier by the carrier first section and the carrier second section.
