Performing welder testing-3

    

 

In general, approval of a welder's capabilities also includes approval of all welds

made by the welder and regarded as easier than the test weld. The validity of approvals

of welders is set out in tables in the standard.

Welder tests must be conducted in accordance with a welding procedure specifi-

cation or welding data sheet. This may be preliminary based on the company's

aggregated welding abilities, or qualified, depending on the particular product require-

ments.

Welder testing must be supervised by an examiner or an examining test body that is

accepted by the contracting parties. The examiners may be employed by the manufac-

turer or purchaser, or by a third party, as determined by the contract requirements. The

highest approval level is given if examining is carried out by an accredited certification

body for certification of personnel.
