AWS D8.8M-2007 Specification for AutomotiveWeld Quality—Arc Welding of Steel

Foreword
This foreword is not part of AWS D8.8M:2007, Specification for Automotive Weld Quality—
Arc Welding of Steel, but is included for informational purposes only.
This specification was developed by the AWS D8C Subcommittee on Automotive Arc Welding of Steel of the AWS D8
Committee on Automotive Welding.
Arc welding of large truck and car frame structures with relatively thick metal parts and gas metal arc welding (GMAW)
using CO2 shielding gas are reflected in AWS D8.8-97/SAE HS J1196, Specification for Automotive and Light Truck
Components Weld Quality—Arc Welding. Prior to AWS D8.8-97, there were two editions of D8.8: AWS D8.8-79/SAE
HS J1196 and D8.8-89/SAE HS J1196, Specification for Automotive Weld Quality—Arc Welding.
This fourth edition, D8.8M:2007, Specification for Automotive Weld Quality—Arc Welding of Steel, includes the following
changes: (1) elimination of annexes dealing with various process issues; (2) updated processes to include hybrid
welding and tandem arc GMAW; and (3) updated weld measurement requirements to reflect industry standards from
Original Equipment Manufacturers (OEMs).
Recent changes in automotive design, caused by the desire to reduce fuel consumption and improve crash performance,
have resulted in automotive structures being made of thinner and higher strength metal parts. This specification was
undertaken to prepare minimum quality standards for arc welding of various types of components. One objective of the
subcommittee was to prepare a specification that would be useful for the OEMs and Tier suppliers of automotive
components who may not have quality standards of their own. Another objective is to get as many of the OEMs and Tier
suppliers to use and specify this document so there is greater consistency.
Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary,
AWS D8 Committee on Automotive Welding, American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126.
