CEN/TC 121/SC 2 - Approval requirements for welding and allied processes personnel

This International Standard defines the requirements for qualification testing of welders for fusion welding of steels.
It provides a set of technical rules for a systematic qualification test of the welder, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body.
When qualifying welders, the emphasis is placed on the welder’s ability to manually manipulate the electrode/ welding torch/ welding blowpipe and thereby producing a weld of acceptable quality.
The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see ISO 14732).

This standard identifies the quality related responsibilities and tasks included  in the coordination of welding related activities. In any manufacturing organization welding coordination may be undertaken by one or a number of persons. Welding coordination requirements can be specified by a manufacturer, contract or an application standard.

This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and certification for the approval testing of welder performance for the welding of aluminium. The recommended format for the certificate of approval testing is given in Annex A.  During the approval test the welder should be required to show adequate practical experience and job knowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to be approved; information on these aspects is given in Annex C.  This standard is applicable when the welder's approval testing is required by the purchaser, by inspection authorities or by other organizations.  This standard applies to the approval testing of welders for the fusion welding of aluminium using gas in shield.  The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. This standard does not cover fully mechanized and fully automatic processes (.).1)  This standard covers approval testing of welders for work on semi-finished and finished products made from wrought, forged or cast material types listed in 5.4.  The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.1)  1.
