Abstract: A technique facilitates a welding operation in a variety of difficult environments, including downhole environments, to enable formation of a dependable connection between components. A tool may be constructed to contain a material mixture used in the welding operation. The tool is conveyed to a position adjacent a weld region of components to be welded together. The material mixture is of a type which may be ignited to initiate a reaction which forms a molten metal from at least one constituent in the material mixture. Additionally, the tool comprises a nozzle oriented to direct the molten metal to the weld region so as to form a secure, welded connection between the components.

Abstract: A charge assembly for incorporation into a downhole tool to induce pressure at an interior of the tool during a downhole application. The assembly includes a reactive powder metals that is particularly configured of a reaction rate slower than that of a high energy explosive directed at the application. Thus, upon triggering of the explosive and downhole application in a high pressure well environment, reaction of the powder metals may serve to substantially reduce any pressure differential at the tool. As such, shock related damage due to sudden introduction of pressure differential wave to the tool may be minimized.
Abstract translation: 一种用于在井下应用期间并入井下工具以在工具内部引起压力的装料组件。 该组件包括反应性粉末金属，其特别构造为比针对应用的高能量爆炸物的反应速率慢的反应速率。 因此，当在高压井环境中触发炸药和井下应用时，粉末金属的反应可用于基本上减少工具处的任何压力差。 因此，可能将由于突然引入压差波而引起的冲击相关的损坏最小化。
