Description / Abstract:
Introduction
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 standard provides the weld acceptance criteria and repair methods for evaluating drawn-arc welded studs, nuts and brackets in automotive products for which GM is responsible for establishing or approving the product design.
Applicability. The criteria established in this standard become mandatory when referenced on a weld design document. Deviation from any weld criteria provided in this standard must be identified on a weld design document.
Remarks.
Usage. Welded structures 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 or non-conforming 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 weld.council@gm.com
As used in this standard, the words “shall” and “must” denote a requirement; the word “should” denotes a guideline; and the word “may” denotes a choice.
