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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, 2 (see www.iso.org/directives ).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee SC 6, Resistance welding and allied mechanical joining and by CEN/TC 121, Welding and allied processes in collaboration.

This second edition cancels and replaces the first edition (ISO 15614-12:2004), of which it constitutes a minor revision with the following changes:

• Annex ZA has been removed;
• ISO 14732 has been added to the Bibliography and has replaced EN 1418.

ISO 15614 consists of the following parts, under the general title Specification and qualification of welding procedures for metallic materials — Welding procedure test:

• Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys
• Part 2: Arc welding of aluminium and its alloys
• Part 3: Fusion welding of non-alloyed and low-alloyed cast irons
• Part 4: Finishing welding of aluminium castings
• Part 5: Arc welding of titanium, zirconium and their alloys
• Part 6: Arc welding of copper and its alloys
• Part 7: Overlay welding
• Part 8: Welding of tubes to tube-plate joints
• Part 10: Hyperbaric dry welding
• Part 11: Electron and laser beam welding
• Part 12: Spot, seam and projection welding
• Part 13: Upset (resistance butt) and flash welding
• Part 14: Laser-arc hybrid welding of steels, nickel and nickel alloys

Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 6 via your national standards body. A complete listing of these bodies can be found at “ www.iso.org .”

Introduction

It is intended that all new welding procedure qualifications be carried out in accordance with this part of ISO 15614 from the date of its issue.

However, this part of ISO 15614 does not invalidate previous welding procedure qualifications made to other standards or specifications, provided the intent of its technical requirements is satisfied and the previous welding procedure qualifications are relevant to the application and production work on which they are to be employed.

Also, where additional tests have to be carried out to make the qualification technically equivalent, it is necessary only to perform the additional tests on a test piece made in accordance with this part of ISO 15614.

The various parts of ISO 15614 comprise, in their turn, a series of International Standards on welding, details of which are given in ISO 15607, Annex A.

1 Scope

This part of ISO 15614 specifies the tests which can be used for qualification of welding procedure specifications for spot, seam, and projection welding processes.

This International Standard is part of the ISO 15614 series. Details of this series are given in ISO 15607, Annex A.

This part of ISO 15614 defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all practical welding operations covered by this part of ISO 15614.

The tests required to qualify the procedure for a particular component/assembly depend on the performance and quality requirements of the component/assembly and shall be established before any qualification is undertaken.

Tests shall be carried out in accordance with this part of ISO 15614 unless more severe tests are specified by the relevant application standard or contract when these shall apply.

The acceptability of applying the principles of this part of ISO 15614 to other resistance welding processes should be established before any qualification is undertaken.

This part of ISO 15614 covers the following resistance welding processes, as defined in ISO 4063:

• 21 – resistance spot welding;
  • 211 – indirect spot welding;
  • 212 – direct spot welding;

• 22 – resistance seam welding;

  • 221 – lap seam welding;
  • 222 – mash seam welding;
  • 225 – foil butt-seam welding;
  • 226 – seam welding with strip;

• 23 – projection welding;

  • 231 – indirect projection welding;
  • 232 – direct projection welding.
