Abstract
Methods and apparatus for plasma-assisted joining of one or more parts together are provided. The joining process may include, for example, placing at least first and second joining areas in proximity to one another in a cavity, forming a plasma in the cavity by subjecting a gas to electromagnetic radiation in the presence of a plasma catalyst, and sustaining the plasma at least until the first and second joining areas are joined. Plasma catalysts, and methods and apparatus for igniting, modulating, and sustaining a joining plasma, are provided. Additional cavity shapes, and methods and apparatus for selective plasma-joining, are also provided.
