Welding audit and quality
Supplier and workshop audits, conformity of welded joints, qualification of procedures and welders: we check that your welded fabrication meets its requirements.
What we check
- the welding quality system according to the ISO 3834 series and, for rail, EN 15085;
- welding coordination: appointment, level and role of the coordinators (ISO 14731);
- welding procedures: specifications (WPS, ISO 15609) and qualifications (WPQR, ISO 15614);
- the qualification of welders (ISO 9606) and of welding operators (ISO 14732);
- inspection and testing, and the conformity of welded joints with the required quality levels (ISO 5817);
- documentary traceability.
Supplier audits
Supplier quality assurance is our core business today: we audit, check the conformity of parts and processes, and ensure documentary traceability. A welding audit at a supplier, before the order or during fabrication, avoids discovering a defect on delivery.
Internal audit before certification
Before a certification or surveillance audit (ISO 3834, EN 15085, EN 1090), an internal audit led by an IWE engineer brings out the gaps to correct: procedures, expired qualifications, coordination, documents.
Frequently asked questions
What are a WPS and a WPQR?
The WPS (welding procedure specification) sets the welding parameters of a joint. The WPQR (welding procedure qualification record) proves, through tests according to ISO 15614, that the procedure produces conforming welds.
What does an ISO 3834 audit check?
The workshop's ability to control the quality of its welds: review of requirements, welding and inspection personnel, coordination, equipment, procedures, materials, inspection, non-conformities and traceability.
