A method and system of inertia friction welding that enables the production of inertia friction welds in which the final upset can be controlled to an operator specified target. The method utilizes any profile-based upset control technique, including but not limited to torque modulation and pressure (load) modulation. The method dynamically modifies the profile upset setpoints to systematically drive the upset formation to produce a weld with the targeted upset. The method and system also enables the production of inertia friction welds in which the final welded part length can be controlled to an operator specified target. The system and associated method comprises inertia friction welding a pair of sample parts to form a sample weld while acquiring data relating to the formation of the sample weld. The system and associated method also comprises inertia friction welding a pair of production parts to form a production weld using the profile data acquired during the friction welding of the pair of sample parts to achieve the predetermined upset formation.
