Information on certification of welders (ISO 9606-1,-2,-3,-4,-5, Tdok 2014:0587), brazers (ISO 13585) and welding operators (ISO 14732)

A welder test certificate is personal and valid for 2 years or 3 years depending on the standard (The certificate can be extended), alternatively 3 years or 6 years (the welder must be retested every 3 or 6 years applies to standards 9606-1 and 14732). The above applies under the condition that the welder has worked in the area for which he is certified and that this is confirmed by the employer with a signature every 6 months (for TDOK every 12 months).

Welder's test, how does it work?

The test can be performed at the own company, the welding school or locally at AFRY in some locations. Before testing, the client must ensure that the equipment and premises are suitable for testing.

Before a test, in good time it is important to inform the certification body whether there are special needs. If this is the case, the certification body must accommodate these needs within reasonable limits, however, regard to national regulations and personal integrity.

A welding test can be broken down into the following four steps:

Step 1 – Customer and welder/welding operator apply for certification. Details of the test are registered such as names and dates of birth of welders/welding operators, welding method, welding position, material qualities and dimensions, pWPS/WPS etc.

Step 2 - A welding examiner from AFRY supervises the testing and verifies that the welder/welding operator follows the specified pWPS/WPS and meets the requirements set in the standard. For ISO 14732 certification, an oral functional knowledge test on the welding station is also carried out.

Step 3 – The welding examiner performs a visual inspection of the sample and if the requirements are met, non-destructive testing (e.g., radiographic/ultrasonic test and/or destructive testing (e.g., fracture test, bend test) is then carried out.

Step 4 – If the test gives an approved result, a welder test certificate is issued.

In addition to the above, you can also take a theoretical knowledge test, which is done in connection with the supervision. For TDOK, the theory test is mandatory both for new certification and for a 6-year extension.


The application for extension must be made to the certification Body. The application must include the signed welder's test certificate and documentation from testing (X-ray, ultrasound, breaking/bending testing). The documentation must verify the quality of 1 or 2 weld, respectively, depending on what the current standard requires, the test must have been carried out in the last six months and be traceable to the welder/operator. (For TDOK, documentation of 5 or 10 joints and 1 ultrasound report per year applies, depending on the method).

Welder test certificates and logos

The certificate must only be reproduced in its entirety, i.e., copy of the entire certificate is permitted. It must not be used in any way to mislead anyone or to lead to misunderstandings about the scope of the certification.


If the conditions underlying the welder test certificate's validity are no longer met, AFRY can withdraw the certificate. The reason for revocation may be that the certificate is used for activities other than those for which the certificate is valid. It may also be the case that incorrect information was provided to AFRY in connection with the welder test. Other reasons may be that the welder has not followed the requirements of the standard/welder test procedure, that the welder has somehow used the certificate in such a way that AFRY has been discredited or has referred to a certificate that has ceased to be valid. The holder of the certificate or their employer is obliged to keep documentation of complaints related to the certificate.

Accreditation and Impartiality

AFRY is accredited by SWEDAC for personal certification according to the requirements of ISO/IEC 17024. Welders, brazer and operator tests are issued by the certification body at AFRY (ÅF Industry AB) as a third-party certificate. We are also a recognized third-party body according to the Pressure Equipment Directive 2014/68/EU (PED). Issued Welder, brazers and operator certificates are the property of the certification body.

Our commitment includes working impartially and independently. All certification assignments must be carried out with confidentiality and without favoring or disfavoring any individual person or any individual company. Examination results are therefore analyzed and compared continuously to monitor and ensure that there are no unreasonable differences.


The certification body's services are charged according to a price list approved by the governing board.
