Abstract: A plug that can seal an aperture in a body includes a base, a main plug portion extending outward from the base, a groove body portion extending from a distal end of the main plug portion and having an outer diameter and a cap receiving portion extending from a distal end of the groove body portion and having a smaller outer diameter than the outer diameter of the groove body portion. The plug also includes a cap installed on the cap receiving portion and a radial sealing element disposed between the cap and the distal end of the main plug portion, the radial sealing element having an inner diameter that is larger than the outer diameter of the cap receiving portion. In operation, the cap is installed onto the cap receiving portion after the radial sealing element has been attached.

Abstract: Systems and methods to control fabrication of an assembly involve a first end sheet having an interior surface and an exterior surface, opposite the interior surface. A system includes interior sheets, the interior sheets including a first interior sheet at one end of a stack of the interior sheets and including a last interior sheet at an opposite end of the stack of the two or more interior sheets, the first interior sheet being adjacent to the interior surface of the first end sheet, and a second end sheet having an interior surface and an exterior surface, opposite the interior surface. The last interior sheet is adjacent to the interior surface of the last end sheet, and the interior surface of the first end sheet or the second end sheet includes venting features, the venting features including holes or slots to channel heat, gas, or vapor during a brazing process.
