Welding, brazing, soldering and cutting - Nomenclature of processes and reference numbers (ISO 4063:2023)

This document establishes a nomenclature for:
—    welding;
—    brazing, soldering and weld brazing;
—    thermal cutting;
with each process identified by a reference number.
It covers the main processes (one digit), groups (two digits) and sub-groups (three digits). The reference number for any process has a maximum of three digits. This system is intended as an aid in computerization and the drafting of, for example, drawings, working papers and welding procedure specifications, and enables the uniform international designation of the processes.
This document does not cover all process variants. The process numbers can be supplemented with additional information for variants not listed.

Schweißen, Hartlöten, Weichlöten und Schneiden - Liste der Prozesse und Ordnungsnummern (ISO 4063:2023)

Dieses Dokument legt eine Nomenklatur fest für:
   Schweißen,
   Hartlöten, Weichlöten und Fugenlöten,
   thermisches Schneiden,
wobei jedes Verfahren durch eine Ordnungsnummer gekennzeichnet ist.

Overview - EN ISO 4063:2023 (ISO 4063:2023)

EN ISO 4063:2023 establishes a standardised nomenclature and reference-numbering system for joining and cutting processes: welding; brazing, soldering and weld-brazing; and thermal cutting. Adopted by CEN as a European Standard, the document defines a hierarchical coding scheme (main processes, groups, sub‑groups) to enable uniform international designation of processes and to aid computerisation, drawings, working papers and welding procedure specifications (WPS).

Example designations from the standard:

• ISO 4063 – 48 (Cold pressure welding)
• ISO 4063 – 62 (Radio frequency welding)
• ISO 4063 – 662‑A (Heated wedge welding with hot gas)
• Hybrid example: ISO 4063 – 522 + 15 (Gas laser welding + Plasma arc welding)

Key topics and technical requirements

• Reference-number structure:
  • Main processes: 1 digit
  • Groups: 2 digits
  • Sub-groups: 3 digits (maximum)
  • Process numbers can be supplemented with letters for variants.
• Designation rules: Full process designations use the format “ISO 4063 – ”. Hybrid processes are expressed by separating process numbers with “+”.
• Scope limitations: The standard lists main processes and many variants but does not claim to cover every possible variant; Annex A recommends ways to supplement numbers for unlisted variants.
• Informative annexes:
  • Annex A - Process variants guidance
  • Annex B - Replaced and obsolete processes
  • Annex C - Common US acronyms for welding and allied processes
• Updates: This fifth edition incorporates welding and thermal joining processes for plastics and supersedes previous editions.

Applications - who uses EN ISO 4063:2023

• Welding engineers and procedure writers: Use standardised codes in Welding Procedure Specifications (WPS) and quality documentation.
• Designers and CAD/BIM users: Apply reference numbers on drawings and fabrication documents for unambiguous process specification.
• Manufacturers and fabricators: Standard codes simplify procurement, process selection and automation setups.
• Inspectors, certifiers and regulators: Ensure consistent process identification across contracts and conformity assessment.
• IT and database managers: Facilitate computerisation of process records, traceability and production analytics.

Related standards and resources

• ISO Online Browsing Platform and IEC Electropedia for related terminology.
• The standard references ISO/TR documents (e.g., terminology such as “shock welding”) and aligns with other ISO/CEN welding standards used for WPS, qualification and testing.

EN ISO 4063:2023 is a practical tool for harmonising how joining and cutting processes are named, recorded and communicated across engineering, manufacturing and quality systems.

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.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 7, Representation and terms, 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 fifth edition cancels and replaces the fourth edition (ISO 4063:2009), which has been technically
revised.
The main changes are as follows:
— incorporation of processes and reference numbers for welding and thermal joining of plastics.

4 Designation
4.1 General
Where a full designation is required for a joining process, it shall have the following structure: the
number of this document (i.e. “ISO 4063”), separated by a dash from the reference number of the
process, as shown in these examples.
EXAMPLE 1 Process “Cold pressure welding” with reference number 48 is designated as:
ISO 4063 – 48
EXAMPLE 2 Process “Radio frequency welding” with reference number 62 is designated as:
ISO 4063 – 62
EXAMPLE 3 Process “Heated wedge welding with hot gas” with reference number 662-A is designated as:
ISO 4063:2023(E)
ISO 4063 – 662-A
4.2 Hybrid joining processes
When multiple processes are used simultaneously in one process area, the processes shall be described
using the designations for each process separated by the symbol “+”.
EXAMPLE Process “Gas laser welding” (reference number 522) together with process “Plasma arc welding”
(reference number 15) is designated as:
ISO 4063 – 522 + 15
