Qualification test of welders - Fusion welding - Part 1: Steels (ISO/DIS 9606-1:2008)

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).

Prüfung von Schweißern - Schmelzschweißen - Teil 1: Stähle (ISO/DIS 9606-1:2008)

Diese Internationale Norm legt die Bedingungen für eine Schweißerprüfung für das Schmelzschweißen von Stählen fest.
Sie stellt eine Reihe technischer Regeln für systematische Prüfungen von Schweißern auf und ermöglicht so, dass solche Qualifizierungen unabhängig von der Art des Erzeugnisses, des Ortes und des Prüfers/der Prüfstelle einheitlich akzeptiert werden.
Wenn Schweißer qualifiziert werden, liegt der Schwerpunkt auf der Fähigkeit des Schweißers, den Elektroden¬halter/die Schweißpistole/den Schweißbrenner so zu handhaben, dass damit eine Schweißung von zulässiger Qualität erzeugt wird.
Die Schweißprozesse nach dieser Norm schließen nur solche Schweißprozesse ein, die als manuelles Schweißen oder teilmechanisches Schweißen bezeichnet werden. Sie schließen nicht die vollmechanischen und automatischen Schweißprozesse ein (siehe ISO 14732).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9606-1 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 11, Qualification requirements for welding and allied processes personnel.
This second edition cancels and replaces the first edition (ISO 9606-1:1994), which has been technically
revised. It also incorporates ISO 9606-1:1994/Amd 1:1998.
Requests for official interpretations of any aspect of this standard should be directed to the Secretariat of
ISO/TC 44/SC 11 via your national standards body, a complete listing which can be found at www.iso.org.

ISO/DIS 9606-1.2 (E)
Introduction
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 standard depends on welding techniques and conditions
used in which uniform rules are complied with, and standard test pieces are used.
The principle of this 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 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 15614-1).

1 Scope
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).

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9606-1 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 11, Qualification requirements for welding and allied processes personnel .

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 standard depends on welding techniques and conditions
used in which uniform rules are complied with, and standard test pieces are used.
The principle of this 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 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 15614-1).
Qualifications in accordance with ISO 9606-1 or any other welder qualification standard existing at the date of
publication of this standard are, at the end of their period of validity, to be interpreted in accordance with the
requirements of this standard.
Requests for official interpretations of any aspect of this standard should be directed to the Secretariat of
ISO/TC 44/SC 11 via your national standards body, a complete listing which can be found at www.iso.org.
1 Scepo
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).
