ISO 3834 is a highly versatile standard designed to be applicable to both workshop and on-site manufacturing of any type of fusion-welded construction, ensuring the quality of the resulting welds. Its application extends to a wide range of industries, including:

Companies manufacturing pressure components, subject to national or international regulations (PED, ASME).
Companies operating in the plant engineering sector** (chemical plants, petrochemical plants, power generation, steel industries, etc.).
Companies manufacturing welded structures for the construction sector.
Companies operating in the railway sector.

Why obtain ISO 3834 Certification?

ISO 3834 certification enables a company to:

Meet contractual requirements, which increasingly demand compliance with this standard.
Define and maintain quality requirements for welding within its organization.
Regulate the management of the "special process" of welding, integrating it into the UNI EN ISO 9001 quality management system.
Ensure compliance with regulatory requirements for welding activities within the framework of European directives (PED, CPD, Simple Pressure Vessels).
Integrate seamlessly with other product and system certifications such as EN 1090 and UNI EN ISO 9001.

UNI EN ISO 3834: how is the standard structured?

ISO 3834 is divided into six parts:

Part 1: Guide for selection and use
Part 2: Comprehensive quality requirements
Part 3: Standard quality requirements
Part 4: Basic quality requirements
Part 5: Documents required to declare conformity with ISO 3834-2, ISO 3834-3, or ISO 3834-4 quality requirements
Part 6: UNI CEN ISO/TR 3834-6 – Guide for the application of ISO 3834
