Measuring the overall length of the welded parts gives a quick check of process repeatability and indicates weld quality. Precise rotational speed and hydraulic pressure govern the rate of heat buildup and rate of compression of the joint for process repeatability. Increased hydraulic pressure pushes the heat-softened parts together until they cool, welded together. Friction heats the contacting surfaces and slows part and flywheel until, having spent the kinetic energy in the flywheel, they stop. At the same time, hydraulics move the non-spinning part forward, pressing it against the spinning part. The machine spins part and flywheel to a predetermined speed, providing the inertia needed for welding, and then releasing them from the drive mechanism. A non-rotated chuck that moves axially under hydraulic pressure holds the other. In a chuck attached to a flywheel of precisely measured mass, the machine holds one part for welding. ![]() Inertia Welding Process Inertia welding actually forges metal together by utilizing the kinetic energy stored in a flywheel system.Īn inertia machine looks much like a conventional shop lathe.
