ABSTRACT:
A process for balancing a crankshaft comprising applying balancing masses onto the outer peripheral surfaces of balancing weight parts of a crankshaft, by welding, in accordance with the degree of unbalance of the shaft and preliminarily forming recesses or projecting portions at positions radially inward of the balancing masses applied by welding to prevent transmission of thermal stress to central journal parts of the crankshaft and thereby preclude bending of the shaft.
