摘要

A welded structural assembly and method are provided, which in one form includes at least one upper substrate, at least one lower substrate disposed adjacent the upper substrate, and a fastener extending through the upper substrate and into the lower substrate. The fastener is welded to the lower substrate and defines a head portion having an outer periphery and an underside. A sealing member is disposed under the head portion and contacts the underside thereof, and further extends beyond the outer periphery of the head portion.
