Abstract: A method for counteracting tensile stress in an article is disclosed, including heating the article and applying compressive stress to the article along a compressive stress vector, the compressive stress vector including a compressive stress vector component opposite in direction to a tensile stress vector of a thermally-induced tensile stress of the article. The compressive stress is applied by thermally-induced autogenous pressure by a fixture contacting the article. A fixture for counteracting tensile stress is disclosed, including a first compression member and a second compression member, and a position lock connecting the first compression member to the second compression member and reversibly fixing the first compression member relative to the second compression member. The first compression member and the second compression member include compressive surfaces having mating conformations for surfaces of an article. The position lock includes a material composition.

Abstract: A process for treating a component comprising the steps of capturing a digital image of a gap in a portion of a component. The gap is characterized as having gap walls, a length and at any point along its length as having the features of an inner width between the gap walls, an outer width between the gap walls, and a depth. One or more of such features is measured at one or more points along all or a portion of the length of the gap. The measurements are used to determine a water jet cleaning path, a cleaning edge relative to a gap wall and path angle. A water jet is passed along all or a portion of the selected path to remove debris and/or a portion of a gap wall. The treated gap is then processed further to join the gap edges using a suitable sealing method.
