scope:

This International Standard establishes a nomenclature for welding and allied processes, with each process identified by a reference number.

This International Standard covers the main groups of processes (one digit), groups (two digits) and subgroups (three digits). The reference number for any process has a maximum of three digits. This system is intended as an aid in computerization, drawings, the drafting of working papers, welding procedure specifications, etc.

NOTE In addition to terms in English and French, two of the three official ISO languages, this International Standard 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.
