ISO 3834:2021 sets forth the quality assurance guidelines for fusion welding of metallic materials, covering both workshop and site activities. It is a globally recognized quality management standard tailored specifically for welding processes. Unlike general ISO standards, ISO 3834 dives deep into welding-specific quality aspects such as welder qualification, welding coordination personnel, inspection procedures, material traceability, and compliance documentation.
This standard is applicable to manufacturers of pressure vessels, structural steel components, pipelines, and other welded products. It is not a standalone certification but complements other certifications like ISO 9001 and EN 1090 for CE Marking.
Welding is a special process—its quality cannot always be fully verified by testing the final product. Therefore, it is crucial to have stringent quality controls in place during the welding process.
