Description / Abstract:
Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. This specification provides the
acceptance criteria for aluminum resistance spot welding in
automotive products for which GM is responsible for establishing or
approving product design.
Applicability. The criteria established in this
specification become mandatory when referenced on a product release
document or Statement of Requirements (SOR). Deviation from any
weld criteria provided in this specification must be approved by
Product Engineering.
Usage. Welds are considered satisfactory when
they meet the expected design service loads and satisfy functional
performance requirements. The evaluation criteria contained in this
document has been established as a basis for the manufacturing
acceptance of welded products and are the same for all welds
regardless of service load. Furthermore, welds identified as
discrepant often retain a percentage of their mechanical properties
and may contribute to the integrity of the welded product.
Application of this specification for other uses, such as
post-crash weld quality assessment, may lead to erroneous results
or conclusions.
Clarification. For clarification of this
specification or editorial comments, email the GM Weld Council at
