The professional skills of a welder are crucial for the quality of welding work.

In order to test and document the welding skills of a person, the welder can be certified for welding according to different welding methods, materials and welding positions. In the field of welding, there are typically customer requirements for certified welders or regulatory requirements, e.g. the essential safety requirements of the Pressure Equipment Directive (PED 2016/68)

The welder can - when the necessary skills have been acquired – be recommended for person certification. The test will cover one or more specific welding standards.

Examination and certification of the welder is carried out by a certification body. DANAK offers accreditation to such certification in accordance with the requirements for person certification ISO/IEC 17024.

Welding procedures, including welding additives, can be tested by an inspection body. DANAK offers accreditation to such inspections in accordance with the ISO/IEC 17020 standard. Welding procedure testing usually takes place at the premises of the company in question.

During the procedure test, the inspection body will follow the standards for specification and qualification of welding procedures that are relevant depending on the welding method and materials.
