| Summary |
"The purpose of this investigation was the design and fabrication of a machine to bond metal to metal using the inertia method of friction welding. This method of bonding is considered far superior to the heretofore employed friction welding processes as will be explained later. The inertia method controls the energy imparted to the weld by using a flywheel which has been brought to a state of predetermined kinetic energy due to rotation. This energy is then transferred to the weld zone in the form of heat due to rotational friction. Hollow specimens with a cross-sectional area of 0.306 square inches have been successfully welded on the present machine. The results show that the machine as designed would be capable of welding materials 1 inch in diameter were it not for the flywheel velocity being limited to 1,000 revolutions per minute due to unbalance"--Abstract, leaf ii. |
