N2 - Silicon carbide (SiC) is a high-performance ceramic renowned for its excellent strength, thermal stability, and corrosion resistance, making it highly critical for advanced applications. Yet, achieving reliable joints remains challenging, especially given the need for localized heating rather than bulk heating of an entire SiC component. Laser-assisted joining has emerged as a promising alternative, offering the advantages of localized heating, rapid processing without the need for pressure, and precise energy control that significantly minimizes impact on adjacent materials. This study examines the feasibility of using two different infrared diode lasers for pressure-less, localized joining of SiC/SiC tubes to SiC/SiC end-plugs. The results are compared with those obtained using conventional furnaces. A silica-alumina-yttria-based glass is utilized as the joining material. The morphology, microstructure, and mechanical strength of the joints are analyzed, with strength evaluated through push tests designed to detach the end-plug from the tube.
