Silicon carbide composite material welding equipment and welding method

The invention discloses silicon carbide composite material welding equipment and a silicon carbide composite material welding method. The welding equipment comprises a supporting device and welding devices arranged on the two sides of the supporting device and used for welding the end plug and the end of the SiC cladding tube. The welding device comprises a workbench, a welding cavity, a heating device and a feeding device, wherein the heating device is arranged on the welding cavity and used for heating the end of the SiC cladding tube, and the feeding device is used for conveying an end plug to the end of the SiC cladding tube and pressing the end plug to the end of the SiC cladding tube. The gas injection device is used for exhausting air in the welding chamber and injecting protective gas into the welding chamber; the spraying device is used for spraying welding flux on an end plug to be welded; the welding cavity is connected with the workbench through a linear sliding mechanism, and a pipe inlet allowin
