Abstract
A crankshaft is manufactured by providing a plurality of initially completely discrete crankshaft segments electron-beam welded together. Tubular bearing journals (12,14) having an inclined surface (30) are positioned in a groove (35,40) of a counterweight web (16) and a groove (50) of a crankshaft end (18). The discrete segments (12,14,16,18) are positioned and maintained in position by the interaction of inclined surfaces (30) and grooves (35,40,50) for electron-beam welding.
