To evaluate mechanical properties of the precision component after joining, nickel base superalloy was welded while subjected to synchronous mechanical vibration. In the vibrated specimen, the weld metal was seen to have fine microstructures, and low residual stress levels were measured in specimens subjected to vibration. Thus, it is believed that the mechanical properties of this vibrated weldment are improved. However, the hardness, strength, and ductility of the weld were compromised when vibration was applied. It was found that cyclic stress plays a role in relieving residual stress, in reducing hardness, and in worsening the mechanical properties.
