ENGINEERINGSTANDARDS Test Methods Materials GM9621P Welding Process Control Procedure 1 Scope 1.1 Purpose. This standard defines weld in-spection and welding equipment process control requirements for producers of GM welded or mechanical clinched product. 1.2 Application. The requirements of this stan-dard are applicable to welding and joining proc-esses utilized by a General Motors fabricating and/or assembly plant to join automotive parts and assemblies. 2 References Note: Only the latest approved standards are applicable unless otherwise specified. 2.1 External Standards/Specifications.

WS-4, GM Weld Verification Procedures. 3 Procedure 3.1 Designation of Responsibility 3.1.1 Product Engineering. The product engi-neering function is responsible for defining the structural requirements of the vehicle. These requirements include the joining method, quan-tity, location,and product tolerances.Product acceptance criteria is to be consistent with pub-lished GM Engineering Standards. 3.1.2 Manufacturing Engineering. The manu-facturing engineering function is responsible for evaluating the product design for manufactura-bility. Manufacturing engineering defines the process, type of tooling, and operational se-quences to manufacture the product in confor-mity to the released design. 3.1.3 Plant Responsibility. The plants must adhere to the product specifications approved by product engineering and the process re-quirements defined by manufacturing engineer-ing. Product engineering must approve any variance from product specifications. Variance from process requirements must be in agree-ment with written procedures. 3.2 Process Evaluation. 3.2.1 Weld Tool Verific...
