ISO 3834-2:2021

ISO 3834-2:2021

ISO 3834 is the key international standard for quality requirements in welding. It sets out how a company must organise its processes to ensure that welding work is carried out consistently, safely and without defects.

As retrospective quality testing of welded joints is extremely time-consuming or even impossible (non-destructive testing has its limits), this standard focuses on preventive quality assurance.

Here is an overview of the key points of the standard:
Target audience: Manufacturers of welded structures, such as plant engineering or pressure vessel construction.
Integration: it is specifically designed to integrate seamlessly into existing management systems such as ISO 9001. Scope: regardless of the type of production, whether series production, one-off manufacture, repair or assembly.

Benefits of certification:
Trust: Customers and regulatory authorities are provided with evidence that you take responsibility for the quality of your welding work.
International recognition: the certification is recognised worldwide.
Process reliability: you document the quality of your work to an internationally standardised level.
The added value of ISO 3834 certification: it demonstrates to your customers, partners, employees and regulatory authorities that you are taking responsibility through this management system.
