EVS-EN 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.
