Full title and description

Welding consumables — Covered electrodes for manual metal arc welding of nickel and nickel alloys — Classification. This International Standard specifies the classification and designation of covered (coated) electrodes intended for manual metal arc (MMA) welding and overlaying of nickel and nickel alloys, based on the chemical composition of the deposited all‑weld metal.

Abstract

This document prescribes requirements for the classification of nickel and nickel‑alloy covered electrodes for manual metal arc welding and overlaying. The classification is based on the chemical composition of the deposited all‑weld metal and includes compositions where nickel is the predominant element. The standard provides a system for designation and identification of covered electrodes used with nickel and nickel alloys.

Scope

The scope covers classification and designation requirements for covered electrodes used in manual metal arc welding and overlaying of nickel and nickel alloys. It applies where the nickel content of the deposited metal is greater than that of any other element. The standard is intended to standardize how electrodes are described and classified for procurement, manufacturing, testing and quality control.

Key topics and requirements

• Classification system for covered electrodes for nickel and nickel alloys based on deposited‑metal chemistry.
• Designation and marking rules for covered electrodes to ensure consistent identification.
• Requirements and limits for chemical composition of deposited all‑weld metal (basis for classification).
• Guidance to link electrode classification with applicable test methods and quality assessment processes.
• Harmonization with related national and regional adoptions (EN/EN ISO formats) where applicable.

Typical use and users

Primary users include welding consumable manufacturers, welding engineers, welding procedure developers, inspection and quality assurance personnel, testing laboratories, procurement teams specifying electrodes for fabrication or repair, and standards bodies adopting or referencing electrode classifications. The standard is used for product specification, procurement, conformity assessment and to support consistent welding practice for nickel alloys.

Related standards

ISO 14172:2023 supersedes ISO 14172:2015 (withdrawn). It is related to other welding‑consumable and test‑method standards (for example standards addressing test methods and quality requirements for consumables and regional EN adoptions of ISO 14172). National and regional bodies have published equivalent EN/EN ISO versions.
