APPLICATION OF INERTIA WELDING TECHNOLOGY TO STEEL DISC-TYPE FLYWHEELS

The program was established to investigate the feasibility of applying inertia welding to the fabrication of steel flywheel assemblies for transportation application. In the inertia welding process, the weld is accomplished by friction and pressure. The parts are literally spun together. The inertia welding characteristics of three steel alloys (Hy-Tuf, 4340, and D6AC) were determined by welding both solid bars (1-in. OD) and tubular specimens (2-in. OD by 0.1-in.-thick wall). In addition, characteristics of the weld and the weld flash (that material extruded from the weld mating surfaces during the welding process) were evaluated. Results indicated Hy-Tuf and 4340 have good welding characteristics, while D6AC is questionable.
