The linear friction welding (LFW) of Haynes 282 Ni superalloy is performed at different applied pressures of 100, 300, and 500 MPa, with a constant oscillation frequency and amplitude. 100 % Joint efficiency is achieved in as-weld and PWHT conditions for 300 and 500 MPa specimens with base metal fracture.
