Who is typically responsible for maintaining WPDS and WPS documentation?

• A. The welding supervisor
• B. The client
• C. The shipping department
• D. The safety officer

Answer: (A)

The person in charge of the welding operation is responsible for maintaining WPDS and WPS documentation. The welding supervisor ensures that a current, approved Welding Procedure Specification is on file, that any Welding Procedure Data Sheets reflect the actual procedures used, and that revisions are controlled and accessible to welders. This keeps welding consistent, traceable, and compliant with the approved procedures. The client may require documentation, but they don’t typically maintain the shop’s internal WPDS/WPS; the shipping department and safety officer handle other duties and aren’t responsible for these welding procedure documents.
