Study the Profile Shape and Mechanical Properties of Bonded Joint HNV3 to Nimonic 80A Superalloy with Inertia Friction Welding Method

This Paper presents the welding parameterchr('39')s effect (forging pressure, welding time) on macrostructure and mechanical properties of friction welding valve steel HNV3 to Nimonic 80A super alloy. For this purpose, two rods with 20 mm diameters are prepared and with using different parameters (Increase forging pressure and welding time) by friction welding method are welded together. Tensile Test carried out on samples for investigating the effect of a parameter. It was discovered that when the welding parameters used in connecting HNV3 and Nimonic 80A Superalloy couple through friction welding were selected correctly; strength of the connection would increase compared to the main material.
