ISO 3834

QUALITY SYSTEM & INSPECTION

ISO 3834

Welding is classified as a special process the result of which cannot be always verified by testing after the end of welding. Therefore, the quality of a weld must be checked during the production not by inspections and tests of the finished product, but by suitable management of welding processes.
This management may be carried out in accordance with the ISO 3834:2005 standard, which ensures quality of the welds of the final product, which then complies with the specified criteria. This standard forms the basis for proving of conformity and certification of products made with the use of a welding process. A certified manufacturer proves compliance with all the principles of this standard - implementing a high-quality welding process within the requirements of product standards or other specifications.

Three levels specified in ISO 3834:

ISO 3834-2 (higher level of quality requirements)
ISO 3834-3 (middle level of quality requirements)
ISO 3834-4 (basic level of quality requirements)
