Overview
EN ISO 3834-4:2021 - Quality requirements for fusion welding of metallic materials, Part 4: Elementary quality requirements - defines the elementary quality requirements for fusion welding of metallic materials in both workshops and field installation sites. Adopted by CEN as EN ISO 3834-4:2021 (superseding the 2005 edition), this standard forms part of the ISO 3834 series and sets the baseline quality controls that manufacturers and contractors must adopt to ensure consistent welding workmanship.
Key Topics and Requirements
- Scope and usage: Applies to fusion welding of metallic materials in workshop and on-site installations; intended as the elementary level within the ISO 3834 hierarchy.
- Review of requirements: Manufacturers must review contractual and technical data, confirm capability, availability of resources and clear documentation before work begins.
- Sub‑contracting: Sub‑contractors work under the manufacturer’s responsibility; manufacturers must supply necessary information and ensure sub‑contractor compliance and record-keeping.
- Welding personnel: Welders and welding operators must be qualified by appropriate tests; manufacturers must provide adequate supervision to assure good workmanship.
- Inspection and testing personnel: All specified inspection and testing shall be carried out; non-destructive testing (NDT) personnel must be qualified. For visual testing, a formal qualification test may not always be required - competence must be verified.
- Equipment and consumables: Welding equipment must be available and maintained in proper working order; welding consumables must be stored and used per supplier recommendations.
- Welding activities and procedures: Welding shall follow an appropriate welding technique and applicable procedural controls.
- Non-conformance and corrective actions: Measures must control non-conforming items or activities to prevent inadvertent acceptance and to promptly identify and correct adverse conditions.
- Quality records: Records shall be retained (minimum five years unless otherwise specified).
Practical Applications
EN ISO 3834-4:2021 is designed to be used where an elementary level of quality assurance for fusion welding is suitable. Typical applications include:
- Fabrication workshops and on-site installation projects with routine welding requirements
- Manufacturers and suppliers of welded assemblies who need a documented, basic quality regime
- Projects where purchasers require demonstrable welding controls but not the more stringent levels of ISO 3834-2 or -3
Who Should Use This Standard
- Welding coordinators, quality managers and production supervisors
- Welding and inspection personnel (including visual and NDT practitioners)
- Manufacturers, fabricators and contractors who perform fusion welding
- Procurement and subcontract managers who need to assess or specify welding quality requirements
Related Standards
