Welding quality: which documents should you ask about?

Start with project requirements

Inspection and documentation should match the specific structure. Avoid copying requirements solely from another project. Ask the designer or quality lead to define what is needed, then discuss it with the contractor before placing the order.

Check document scope and validity

A certificate published online is supporting information. When selecting a contractor, request the current document and check its scope. Agree which personnel qualifications, procedures and production records are required for your project.

Agree handover records early

Final records are easier to prepare when the required list is known from the start. Agree component identification, inspection records and the handover format. Clear requirements reduce the need to reconstruct information after erection is complete.

• Current documents relevant to the order scope.
• An agreed inspection and acceptance plan.
• A list of records to be handed over to the investor.
