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 standard provides the acceptance
criteria and repair procedures for weld-through sealer(s) in
automotive products for which GM is responsible for establishing or
approving product design. 1.2
Applicability. This standard applies to any
application where a weld-through sealer(s) capable of being pumped
at ambient temperatures and intended for use in the body shop is
used to seal body joints against water, dust and air intrusion.
The criteria established in this standard become mandatory when
referenced in product release information or an approved Product
Quality Standard (PQS) document. Deviations from any sealer
criteria provided in this standard must be identified in product
release information or an approved PQS document.
Usage. Weld-through sealed structures are
considered satisfactory when they provide leak-free seams in
identified water paths, and prohibit water intrusion to meet
corrosion requirements for a required period. Corrosion
requirements in structures containing "weld-through" sealer in a
vehicle are varied in both type and magnitude and cannot be
addressed by this standard. Therefore, while the sealer quality
criteria of this standard are consistent with service requirements,
they have been established specifically for use in process and
product monitoring. Any attempted application of this document to
other uses may lead to an erroneous result or conclusion.
Clarification. For clarification of this
standard or editorial comments, email the GM Weld Council at:
weld.council@gm.com.
Proposed changes to this standard must be presented to the
Global Weld Council. To suggest a change to this standard,
reference the "Procedure for Weld Standard Changes" on the Weld
Council's web page.
