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 15609-6 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding.

ISO 15609 consists of the following parts, under the general title Specification and qualification of welding procedures for metallic materials — Welding procedure specification:

• Part 1: Arc welding
• Part 2: Gas welding
• Part 3: Electron beam welding
• Part 4: Laser beam welding and cladding
• Part 5: Resistance welding
• Part 6: Laser-arc hybrid welding

Requests for official interpretations of any aspect of this part of ISO 15609 should be directed to the Secretariat of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be found at www.iso.org .

1 Scope

This part of ISO 15609 specifies requirements for the content of welding procedure specifications for laser-arc hybrid welding processes.

Variables listed in this part of ISO 15609 are those influencing the quality and the properties of the welded joint.

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 11145, ISO 15607 and ISO/TR 25901 and the following apply.

3.1

hybrid welding

two or more fusion welding processes which interact in a single melt pool

Note 1 to entry: Hybrid welding is different than combinations of processes where at least two melt pools exist which are completely separated by a solid component in the solidification phases. Examples of a) a combined process and b)a laser-arc hybrid welding process are given in Figure 1 by the use of a laser beam and the additional energy source of an arc.
