DIN EN ISO 3834-3:2021-08

Reliably implementing quality requirements for fusion welding of metallic materials

DIN EN ISO 3834-3 specifies the standard quality requirements for fusion welding of metallic materials. It helps companies systematically plan, monitor and document welding production processes. The standard provides a consistent basis for quality assurance in welding and supports evidence of controlled and reproducible production quality.

What is DIN EN ISO 3834-3 about?

The standard defines requirements for the organization and execution of welding production processes. It focuses on welding personnel, welding coordination, welding procedures, inspections, traceability and quality documentation. It also describes requirements for reviewing customer requirements, technical production planning, managing subcontracting, and calibrating and validating inspection and measuring equipment.

Topics covered

• Quality requirements for fusion welding of metallic materials
• Review of requirements and technical review
• Qualification of welders and welding coordination personnel
• Qualification of welding procedures
• Production planning and welding procedure specifications
• Monitoring and inspection before, during and after welding
• Calibration and validation of measuring, monitoring and inspection equipment
• Identification, traceability and quality records
• Management of nonconformities and corrective actions

Practical relevance

In numerous industries, welded joints have a direct impact on the safety, function and service life of components and structures. DIN EN ISO 3834-3 helps companies systematically implement and demonstrate compliance with welding quality requirements. This makes it possible to standardize production workflows and document quality requirements in a transparent manner.

The requirements relating to welding personnel, procedure qualification, inspections, traceability and quality documentation are particularly relevant, as they form the basis for controlled production and for providing evidence to customers, auditors and inspection bodies.
