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 3.

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.

Introduction

In prEN ISO 15607, one of the methods of welding procedure qualification is by relating to previous welding experience.

Many manufacturers have considerable experience in fabricating welded structures. Welded components and structures may have been supplied to end users/clients for a variety of applications and have performed satisfactorily over a period of time in service. If this experience is traceable and documented this standard provides a route to welding procedure qualification based on this experience.

Specification and qualification of welding procedures for metallic

materials — Qualification based on previous welding experience

1 Scope

This standard is a part of a series of standards, details of this series are given in EN ISO 15607, Annex A.

This standard gives the necessary information to explain the requirements referenced in EN ISO 15607 about the qualification of welding procedures based on previous welding experience.

In addition it gives the range of qualification and the validity.

The use of this standard may be restricted by an application standard or a specification.

2 Normative references

This European standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

CR ISO/TR 15608, Welding - Guidelines for a metallic material grouping system.

EN ISO 15609, Specification and qualification of welding procedure for metallic materials - Welding procedure specification. (see Annex A)

EN ISO 15614, Specification and qualification of welding procedures for metallic materials - Welding procedure test. (see Annex A)

3 Terms and definitions

For the purposes of this International Standard, the terms and definitions given in EN ISO 15607 apply.

4 Preliminary welding procedure specifications (pWPS)

The qualification of a welding procedure related to previous welding experience shall be based on a pWPS according to the relevant part of prEN ISO 15609. This pWPS shall specify the range for all the relevant parameters.

5 Qualification of the welding procedure

 documentation of the existing previous welding experience (see clause 6).

6 Existing previous welding experience

Previous welding experience shall be demonstrated by documented examination and/or test data and either a summary of welding manufacturing or satisfactory service performance. This shall involve:

a) Satisfactory documentation of weld tests (e.g. non-destructive, destructive, leak or pressure tests) in all cases.

AND either

b) A summary of welding manufacturing of at least one year during an appropriate period

OR

c) Suitability of welds in service for an appropriate period.

A period of five years is considered as an appropriate period unless otherwise specified .

7 Range of qualification

The range of qualification given to a welding procedure qualified in accordance with this standard shall be as given in the appropriate part of EN ISO 15614.

8 Validity

The qualified welding procedure related to previous welding experience is valid as far as the welding production is carried out in the specified range, see clause 6.

9 Welding Procedure Qualification Record (WPQR)

The WPQR shall consist of documentation of existing previous welding experience (see clause 6).

The relevant items listed for the WPS in the relevant part of EN ISO 15609 shall be included. The WPQR shall be signed and dated by the examiner or examining body.
