In this Experiment, We conducted Self-Welding Test about the Refractory Metal such as Tungsten, Molybdenum and Hard Metal (ex. Chrome-Carbide, Stellite No.6), Nickel, Niehrome. The Following Results were obtained. (1)Chrome-Carbide (coated with Detonation Gun) was effective as an Anti-Welding Material, but the Carbide with the content of Tungsten showed a strong Tendency to Self-Welding. (2)Tungsten and Molybdenum (coated with Wire Explosion Gun) were effective as Anti-Welding Materials. (3)Stellite No.6 combinated with Austenitic Stainless Steel (SUS316) showed a Tendency to Self-Welding. (4)Nickel and Nichrome were completely Self-Welded by the Formation of Diffusion Zone.
