Abstract
Similar friction welding were produced using 15 mm diameter solid bar in Ni-base superalloy(alloy718) to investigate their mechanical properties. The main friction welding parameters were selected to endure good quality welds on the basis of visual examination, tensile tests, AE total counts and ultrasonic attenuation coefficient. The specimens were tested as welded, not heat-treated. The tensile strength of the friction welded joints was increased up to 90% of the alloy718 base metal under the condition of all heating time. Optimal welding conditions were n=2,000 (rpm),
