Which documents must be referenced before welding can take place?

• A. Welding Procedure Specification and Procedure Qualification Record
• B. Welding safety checklist and PPE requirements
• C. Material certification and weld metal supplier data
• D. Inspection and test plan

Answer: (A)

In welding, you must have a documented method and proof that it actually works before starting production. The welding procedure specification sets out exactly how the weld should be made—process, base and filler metals, joint design, positions, shielding, and the welding parameters like current, voltage, and travel speed. The procedure qualification record provides the actual test data showing that this procedure yields welds meeting the required acceptance criteria. Together, they confirm both how to weld and that the method can produce reliable, code-compliant results. Safety checklists and PPE are essential for safe operation, but they don’t validate the welding method or prove it will meet required properties. Material certifications and supplier data are important for traceability and compatibility, but they don’t certify the welding procedure itself. An inspection and test plan guides how welds will be checked after fabrication, not the authorization to weld in the first place.
