ADAPTING HSLA STEEL TO WELDED WHEEL RIMS

Failures identified as rare-earth-containing oxide inclusions had acted as stress raisers to start cracks. An electronic instrument for controlling flash welds, a proportional energy regulator (PER), was used on one trial run. Per control coarsened grains at weld centerlines, extended heat-affected zones, altered inclusions from elongated to globular at weld centerlines, and broadened regions of localized softening at edges of heat-affected zones. These factors lowered deformation around centerline inclusions, thereby reducing tears in welds.
