BS EN ISO 9606-1:2013 pdf.Qualification testing of welders – Fusion welding – Part1:Steels.
The ability of a welder to follow verbal or written instructions and verification of a person’s skills are important factors in ensuring the quality of the welded product.
The testing of a welder’s skill in accordance with this International Standard depends on the welding techniques and conditions used, in which uniform rules are complied with and standard test pieces are used.
The principle of this International Standard is that a qualification test qualifies a welder not only for the conditions used in the test, but also for all other conditions which are considered easier to weld in accordance with this International Standard. It is presumed that the welder has received training and/or has industrial practice within the range of qualification.
The qualification test can be used to qualify a welding procedure and a welder provided that all the relevant requirements, e.g. test piece dimensions and testing requirements are satisfied (see ISO 156141[hhi).
All new qualifications shall be in accordance with each part of this International Standard from its date of issue.
At the end of its period of validity, existing qualification tests of welders in accordance with the requirement of a national standard may be revalidated according to this International Standard. This is providing that the technical intent of this International Standard is satisfied. It is necessary for the new range of qualification to be interpreted in accordance with the requirements of this International Standard.
This part of ISO 9606 specifies 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 or examining body.
When qualifying welders, the emphasis is placed on the welder’s ability manually to manipulate the electrode, welding torch or welding blowpipe, thereby producing a weld of acceptable quality.
The welding processes referred to in this part of ISO 9606 include those fusion-welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes.
