Full title and description

Welding consumables — Solid wire electrodes, solid strip electrodes, solid wires and solid rods for fusion welding of nickel and nickel alloys — Classification. This international standard defines a classification system for solid wire and rod welding consumables intended for fusion welding of nickel and nickel‑based alloys, based primarily on chemical composition and intended uses (including guidance that the principles can be applied to metal powders for cladding, hard facing and additive manufacturing).

Abstract

This document specifies requirements for classification of solid wire electrodes, solid strip electrodes, solid wires and solid rods for fusion welding of nickel and nickel alloys. The classification is based on chemical composition and covers compositions in which nickel is the predominant element. The standard’s principles are stated to be applicable to metal powders used for cladding, hard‑facing and additive manufacturing.

Key bibliographic and lifecycle information as published by ISO.

Scope

Specifies requirements for classification of solid wire electrodes, solid strip electrodes, solid wires and solid rods used for fusion welding of nickel and nickel alloys. The classification is based on chemical composition (including alloys where nickel content exceeds that of any other element). The standard also notes that its classification principles can be applied to metal powders for cladding, hard facing and additive manufacturing.

Key topics and requirements

• Classification of solid welding consumables for nickel and nickel alloys according to chemical composition.
• Definitions and designation rules for solid wire electrodes, solid strip electrodes, solid wires and solid rods used in fusion welding.
• Scope of application explicitly covering compositions with nickel as the predominant element and guidance extending to metal powders (cladding/additive manufacturing).
• Alignment with ISO/TC 44/SC 3 work on welding consumables and replacement of the previous 2010 edition.
• Information intended to support procurement, specification and identification of nickel‑alloy welding consumables.

Typical use and users

Used by welding engineers, materials and metallurgical engineers, consumable manufacturers, quality and inspection personnel, procurement/specification writers and standards committees. Typical applications include selection and specification of consumables for fusion welding of nickel alloys in aerospace, chemical processing, power generation, oil & gas, marine and other industries requiring corrosion‑resistant or high‑temperature nickel‑based welds.

Related standards

This edition (ISO 18274:2023, ed. 3) replaces ISO 18274:2010 (withdrawn). It is part of the ISO family of welding‑consumable classification documents produced by ISO/TC 44/SC 3 and is commonly referenced alongside other welding consumable standards and national/adopted versions (EN/ISO national adoptions).
