A WPDS is intended to be used in conjunction with which document?

• A. WPS
• B. QA Manual
• C. Safety Plan
• D. Inspection Report

Answer: (A)

WPDS stands for Welding Procedure Data Sheet, and it is used alongside the approved Welding Procedure Specification. The WPS defines the accepted welding procedure, while the WPDS records the actual variables used on a specific weld or production run to show traceability and conformity with that procedure. By linking the WPDS to the WPS, you can verify that materials, process, parameters (such as preheat, interpass temperature, heat input), and filler metal used match what was approved. This pairing ensures consistent quality and provides a clear record for quality control and audits. Other documents like a QA Manual, Safety Plan, or Inspection Report serve different purposes and do not establish the welding procedure data in relation to the approved WPS.
