Description / Abstract:
Note: Nothing in this standard supersedes
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 acceptance
criteria and repair procedures for arc welds and arc brazes in
automotive products for which GM is responsible for establishing or
approving product design. This standard does not apply to arc spot
welds or arc plug welds.
Applicability. This standard applies to steels
approved by GM for the following types of arc welding or arc
brazing processes:
Arc Welding:
• Gas Metal Arc Welding (GMAW)
• Gas Tungsten Arc Welding (GTAW)
• Flux Cored Arc Welding (FCAW)
• Shielded Metal Arc Welding (SMAW)
• Plasma Arc Welding (PAW)
Arc Brazing:
• Gas Metal Arc Brazing (GMAB)
• Gas Tungsten Arc Brazing (GTAB)
• Plasma Arc Brazing (PAB)
• Flux Cored Arc Brazing (FCAB)
The criteria established in this standard become mandatory when
referenced on a weld design document.
Deviations from any criteria provided in this standard must be
identified on a weld design document.
Usage. In this standard, the terms "braze and
brazing" are used interchangeably with "weld and welding" when used
for the evaluation of an arc braze.
Welded structures are considered satisfactory when they carry
the intended service loads for a required period. Service loads on
weldments in a vehicle are varied in both type and magnitude and
cannot be addressed by this standard. Therefore, while weld quality
criteria of this standard are consistent with service loading
requirements, they have been established specifically for use in
process and product monitoring. Any attempted application of this
document to other uses, such as post-crash braze/weld quality
assessment, may lead to an erroneous result or conclusion.
Discrepant braze/welds by retaining a portion of their engineering
properties may still contribute to the integrity of the
assembly.
Clarification. For clarification of this
standard or editorial comments, email the GM Weld Council at

Proposed changes to this standard must be presented to the GMNA
Weld Council. To suggest a change to this standard, reference the
"Procedure for Weld Standard Changes" on the Weld Council's web
page.
