AWS D8.2M:2017 expresses the quality characteristics and metrics pertinent to individual resistance spot weldson automotive aluminum structures. The acceptance criteria are the same for all welds regardless of the service load andintended to be applied in conditions typically encountered during manufacturing. Welds at variance from the stated weldquality criteria in this document can still have mechanical properties that satisfy product and design requirements as peragreement between customer and supplier. Any attempted application of this document or the evaluation criteria usedherein to other uses, for example post-crash weld quality assessment, may lead to an erroneous result.
