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, 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 15614-13 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 6, Resistance welding and allied mechanical joining.

This second edition cancels and replaces the first edition (ISO 15614-13:2005), which has been technically revised.

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 and gas welding of copper and its alloys
• Part 7: Overlay welding
• Part 8: Welding of tubes to tube-plate joints
• Part 9: Arc underwater hyperbaric wet welding
• 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 part of ISO 15614 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 .

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 15607:2003, Annex A.

1 Scope

This part of ISO 15614 specifies tests for the qualification of welding procedure specifications applicable to upset (resistance butt) welding and flash welding of metallic materials, e.g. with solid, tubular, flat or circular cross-section. Its basic principles can also be applied to other resistance welding processes when this is stated in the specification.

This part of ISO 15614 defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all the practical welding operations that it covers. The tests required to qualify the procedure for a particular component or assembly depend on the performance and quality requirements of the component or assembly, as defined in the design specification. The tests are intended to be carried out in accordance with the requirements of this part of ISO 15614, unless more severe tests are specified by the relevant application standard or specification and when these apply.

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

• 24 flash welding, using direct current or alternating current with various movement sequences, constant flashing and pulsed flashing;
• 25 resistance upset welding, using direct current or alternating current with various pressure sequences.
