AS/NZS 2980:2007
Qualification of welders for fusion welding of steels
Defines the qualification test of welders for the welding of steels to the requirements of a welding procedure specification. 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.
