TS IEC 60050-851

TS IEC 60050-851 is the part of the International Electrotechnical Vocabulary devoted to electric welding, providing a consistent terminology for this technical field. In welding practice, equipment, process auxiliaries, consumables, and operating principles are closely related but not interchangeable concepts; a vocabulary standard helps keep those distinctions clear. This document serves as a reference framework for the terms used in electric welding.

How the terminology is organised

The subject covered by this standard is the terminology used in electric welding applications. In general technical context, this includes arc welding, plasma welding, wire feeding systems, cooling arrangements, gas consoles, and devices used for arc striking and stabilising. As an IEV part, the standard is concerned with naming and distinguishing these elements so that equipment classes, process functions, and consumables are described with precision and without ambiguity.

What the revised edition adds conceptually

The supplied scope states that the second edition replaces the first edition and represents a technical revision. It also shows that, as technology and standardisation developed, new terms were added in several sections. In particular, the expansion covers motor-driven equipment, arc striking and stabilising devices, plasma welding equipment, and a broader set of consumables and associated welding equipment. This indicates that the vocabulary was updated to reflect newer equipment arrangements and terminology used in practice.

The part is identified as a horizontal standard in accordance with IEC Guide 108, which means it supports a common technical language across the field rather than focusing on a single product type. Its value lies in improving clarity in engineering documentation, training, catalogues, and technical communication wherever electric welding terms are used.
