EN ISO 15612:2004 (E) 4 Introduction In EN ISO 15607, one of the methods of welding procedure qualification is by adoption of a standard welding procedure. EN ISO 15612:2004 (E)51 Scope This standard gives the necessary information to explain the req
20、uirements referenced in EN ISO 15607 about the qualification by adoption of a standard welding procedure, and establishes the conditions, limits and ranges of qualification necessary for the use of a standard welding procedure. This standard gives the manufacturer the possibility to use welding proc
21、edures based on welding procedure tests performed by other organisations. This standard is a part of a series of standards, details of this series are given in EN ISO 15607:2003, annex A. The use of this standard can be restricted by an application standard or a specification. 2 Normative references

31、hall be based on a pWPS according to the appropriate part of EN ISO 15609. This pWPS shall specify the range for all the relevant parameters. 5 Qualification by adoption of the standard welding procedure 5.1 General The qualification of the welding procedure shall be carried out by an examiner or an
32、 examiner body according to EN ISO 15607. It shall be verified that examination and testing have been carried out in accordance with the appropriate part of EN ISO 15614. After qualification, the preliminary welding procedure specification will be considered as a standard welding procedure specifica
33、tion. Changes outside the range of qualification given in the appropriate part of EN ISO 15614 as modified in 5.2 shall require a new qualification welding procedure. The welding procedure shall be qualified by the manufacturer and if applicable, verified by an examiner or examining body in accordan

36、ng procedure 6.1 General A standard welding procedure prepared and documented in accordance with clause 8 can be used without further tests providing the following requirements and limitations are observed. 6.2 Related to the user of a standard welding procedure The user of a standard welding proced
37、ure is responsible for the appropriate selection and application of the standard welding procedure. The use of a standard welding procedure requires welding coordination in accordance with EN 719 and that the user fulfils quality requirements in accordance with the appropriate part of EN 729. 6.3 Re
38、lated to the welding equipment The standard welding procedure is qualified for use in production with welding power sources and welding equipment having electrical and mechanical characteristics which are capable of achieving those used in preparing the test weld for qualification of the standard we

The equipment used during production shall permit control of all essential welding parameters. 6.4 Related to the personnel A standard welding procedure shall only be used by welders or welding operators for mechanized equipmen
40、t qualified in accordance with the relevant part of EN 287 or EN ISO 9606 or EN 1418. EN ISO 15612:2004 (E) 8 7 Validity A standard welding procedure remains valid until it is withdrawn or revised. 8 Preparation and documentation The standard welding procedure shall be issued as a specification cove
41、ring ranges for all relevant parameters. Any restrictions, e.g. equipment performance or environmental conditions, shall be stated, as appropriate. The specification shall be in the format of a welding procedure qualification record WPQR according to the relevant part of prEN ISO 15614. The new WPS
42、shall be signed and dated by the manufacturer and, if applicable, verified by an examiner or examining body. Any amendments or revisions shall be re-qualified. All records on which the qualification is based shall be traceable to the original source during the entire period of its use. EN ISO 15612:
