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, Part 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, Part 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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 6, Resistance welding and allied mechanical joining, in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 17677-1:2019), of which it constitutes a
minor revision. The main changes compared to the previous edition are as follows:
— the terms and definitions of ISO 14329 have been implemented;
— editorial changes have been made.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.

Resistance welding — Vocabulary —
Part 1:
Spot, projection and seam welding
1 Scope
This document establishes a vocabulary of terms and definitions for resistance spot welding, projection
welding and seam welding.
NOTE In addition to terms used in English and French, two of the three official ISO languages, this document
gives the equivalent terms in German; these are published under the responsibility of the member body for
Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO
terms and definitions.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1 Welding and testing procedures
3.1.1
chisel test
test in which a chisel is driven between the sheets near to adjacent welds until either fracture occurs or
until the metal near the weld yields or bends
3.1.2
cross tension test
tensile test of a resistance welded specimen to determine the mechanical properties and failure mode
of the weld
3.1.3
cross-wire welding
projection welding (3.1.11) of crossed wires or rods
3.1.4
direct welding
resistance welding secondary circuit variant in which welding current and electrode force (3.3.5) are
applied to the workpieces by directly opposed electrodes (3.2.1) and only one weld is made by one
welding operation
Note 1 to entry: See Figure 12 for typical arrangements.
ISO 17677-1:2021(E)
3.1.5
indirect welding
resistance welding secondary circuit variant in which the welding current flows through the workpieces
in locations away from, as well as at, the welds
Note 1 to entry: See Figure 13 for typical arrangements.
3.1.6
multiple impulse welding
welding with more than one impulse
Note 1 to entry: See Figures 4 to 7 for related time and electrode force (3.3.5) diagrams.
3.1.7
multiple spot welding
spot welding in which two or more welds are made simultaneously in one welding operation
Note 1 to entry: Examples are parallel spot welding (3.1.8) and series spot welding (3.1.14).
3.1.8
parallel spot welding
resistance welding secondary circuit variant in which the secondary current is divided in parallel
electrical paths to make two or more welds simultaneously
Note 1 to entry: See Figure 11 a).
3.1.9
peel test
destructive test in which a resistance-welded lap joint is tested by applying a peel force which results in
stresses mainly in the thickness direction of the weld
3.1.10
pillow test
destructive test in which internal pressure is applied in order to test for leaks and the strength of a
seam weld
3.1.11
projection welding
resistance welding in which the resulting welds are localized at predetermined poin
