Two-year renewal
Since SS-EN ISO 9606-3 does not allow a three-year rule, the certificate is only valid for two years.
To extend the certificate for another two years, the following conditions must be met:
1. 6-month confirmation
A responsible person at the employer must, every six months, confirm that the welder continues to work within the qualified scope.
2. Traceable documentation
All documentation and evidence used to support the extension must be traceable to the welder and clearly state which WPSs have been used in production.
3. Testing of a weld
In the past six months, a weld must have been tested – either by volumetric testing (e.g., radiographic or ultrasonic testing) or mechanical testing (e.g., fracture or bend testing).
4. Acceptance criteria
The tested weld must meet the acceptance limits for discontinuities and shape deviations specified in the standard (e.g., in the section on acceptance criteria).
5. Recreation of original conditions
The test results must demonstrate that the welder has recreated the original conditions of the test.
