This specification expresses the quality characteristics and metrics pertinent to individual resistance spot welds on automotive aluminum structures. The acceptance criteria are the same for all welds regardless of the service load and intended to be applied in conditions typically encountered during manufacturing. Welds at variance from the stated weld quality criteria in this document can still have mechanical properties that satisfy product and design requirements as per agreement between customer and supplier. Any attempted application of this document or the evaluation criteria used herein to other uses, for example post-crash weld quality assessment, may lead to an erroneous result.
