Metalik Malzemelerin Ergitme Kaynağı İçin Kalite Şartları (EN 3834 Belgesi)

EN ISO 3834: Welding Manufacturing Competence Management System
1. What is EN ISO 3834?
EN ISO 3834 is an international standard that defines the quality requirements for manufacturers who manufacture metallic materials using the fusion welding method. It is not a product standard, but a process-focused quality management system. Its aim is to ensure that welded manufacturing is performed to the desired quality and consistency at every stage, from the design phase to final inspection.
🔧 Fundamental Principle: The standard is based on the principle that the quality of a welded product can be ensured by applying the correct processes during manufacturing, not by subsequent testing. Therefore, it controls all welding-related activities (personnel, equipment, procedures, consumables, inspections).
📝 Scope:
• Technical review and design: Analysis of customer and standard requirements.
• Personnel: Competence of welding coordination personnel, welders, and NDT operators.
• Equipment and consumables: Equipment maintenance, calibration, and proper consumable management.
• Procedures: Welding procedure specifications (WPS) and method approval records (PQR).
• Inspection and testing: Checks performed before, during, and after production.
• Traceability: Backtracking of material and welding.
✅ 2. What are the advantages?
Advantage Description
Proven Quality Capability: Proves your welded manufacturing competence to customers and inspection organizations.
Cost Reduction: Increases efficiency by minimizing faulty manufacturing, repairs, and rework.
Process Control and Consistency: Provides a systematic structure that ensures the production of the same quality product every time.
Forms the Foundation for Other Standards: Provides the mandatory infrastructure for many standards such as EN 1090 and EN 15085.
Market Reliability: Increases brand reputation and provides a competitive advantage in tenders.
🛠️ 3. What Competencies Does This Standard Provide?
Competence Provided Description
Controlled Welding Processes Welding operations become planned, approved, and auditable.
Competent Personnel Management Welding coordinator, welder, and supervisor competencies are defined and maintained.
Full Traceability The entire process, from the materials used in the product to the welder performing the work, can be traced back.
Documented Quality The quality level is recorded with technical documents such as WPS and PQR.
Compliance with Customer Requirements The quality assurance required in contractual and technical specifications is provided.
🏭 4. What is its Importance in the Industry?
EN ISO 3834 is considered the "quality constitution" of welded manufacturing. It is a fundamental requirement in all quality-critical industries.
• It is indispensable for steel/aluminum structure manufacturers who will affix the CE mark under EN 1090.
• It is a contractual obligation in high-risk areas such as pressure vessels, railway vehicles, the defense industry, and power plants.
Industry Application Areas
Steel Structures and Construction: All buildings, bridges, and stadiums within the scope of EN 1090.
Pressure Vessels and Boilers: Manufacturing of boilers, tanks, pipelines, and heat exchangers.
Railway Vehicles: Welded joints of wagon frames, bogies, and components (in accordance with EN 15085).
Energy and Petrochemicals: Pipelines, refinery equipment, and turbine components.
Defense and Aerospace: Armored vehicle bodies, military equipment, and ground support systems.
