Welding and allied processes - Nomenclature of processes and reference numbers
This International Standard establishes a nomenclature, with reference numbers, for welding and allied processes.
Each process is identified by a reference number.
This International Standard covers main groups of 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 computerisation, drawings, working papers, welding procedure specifications etc.
