Pressure-regulating inertial friction welding system and method

A pressure-regulating inertial friction welding system, comprising:

• an inertial friction welding machine comprising a flywheel set and a tailstock arranged oppositely, the flywheel set and the tailstock being provided with clamping assemblies configured for clamping a rotation workpiece to be welded and a feed workpiece to be welded respectively, the flywheel set being connected to a rotation driving element via a clutch, and the tailstock being connected to a servo feed assembly;
• and
• a control assembly comprising a controller, a strain gauge and a temperature monitor, the strain gauge having an attaching surface to be attached to the feed workpiece to be welded corresponding to the tailstock and being capable of measuring and obtaining strain data of the feed workpiece to be welded and sending the strain data to the controller, the temperature monitor having a monitoring area covering welding zone between the rotation workpiece to be welded and the feed workpiece to be welded, and the temperature monitor being capable of sending a temperature of the welding zone to the controller;
• and the controller being configured to control the servo feed assembly to regulate a pressure between the rotation workpiece to be welded and the feed workpiece to be welded.
