Welding qualifications

Do you wish to demonstrate that you are professionally competent and are competent to perform high quality welding? This for a specific welding process and within a specific scope of validity? Our rich experience in welding qualifications guarantees a qualification tailored to your needs that conforms to the applicable standards.

A weld is a permanent joint, the quality of which is essential for the lifetime, the reliability and the safety of a welded structure. A qualified welder offers certainty concerning the technical ability and personal skills of a welder, and a proof that the concerned person can execute a high quality weld (for example, without defects) with a particular welding process, and within a particular scope of validity. A qualified welding procedure provides proof that a specifically defined welding method results in a high quality joint, the quality of which (for example, the mechanical properties) are as good as, or even better than, the properties of the base materials that are joined.

In both cases, a test piece is welded in the presence of the assessor. The necessary tests and inspections (laid down under the specific qualification standard) are conducted, and if their results are positive, the assessor will accordingly issue certificates, specifying the scope of validity.

Vinçotte is active in a large number of sectors in the welding construction industry, and is thoroughly up-to- date as regards the many national and international standards relating to welding qualifications. That makes us the right choice as assessor for all your qualifications. For customers, our decades of experience in this field are an excellent guarantee of the quality of the certificates issued.

Since Vinçotte is a member of the CEOC (European Confederation of Inspection Organisations), our certificates are recognised and accepted by other European Member States.

As a “Notified Body” 0026, Vinçotte can also approve existing certificates as per the requirements of European Directive 97/23/EC, Annex

A welding qualification provided by us thereby automatically satisfies and is recognised by all other Notified Bodies in all European Member States.


To ensure the high quality of welded structures, most European Directives, construction standards and regulations prescribe that the welding work must be carried out by qualified welders, in conformity with qualified welding procedures. Based on National regulations, contractual provisions or specifications, manufacturers or contractors may be required to avail of the services of an independent inspection organisation such as Vinçotte, for the required qualifications.
