ISO 3834-2:2005

Certification of welding companies


The ISO 9001 standard stipulates the regulation of specific processes, such as the welding of components. The specific requirements are defined in the ISO 3834-2 standard. It is suitable for welding operations that make products in regulated and unregulated fields. Certification pursuant to ISO 3834-2 highlights the great significance of welding.


ISO 3834-2 supports customer-oriented solutions and optimises process control. It reduces risks and costs.

Target groups

Manufacturers of welded components in regulated and unregulated fields.


3 years - there is an annual audit to ensure that standards are being maintained and a recertification audit after 3 years.


The SQS certificate of conformity with ISO 3834-2 has international validity and is recognised worldwide through the IQNet partnership.


ISO 3834-2 can be extended to the integrated management system in combination with ISO 9001 (quality management), ISO 14001 (environmental management) and OHSAS 18001 (occupational health and safety).
