Описание (английский):

This document prescribes requirements for the classification of nickel and nickel-alloy covered electrodes for manual metal arc welding and overlaying. The classification of the covered electrodes is based on the chemical composition of their deposited all-weld metal. It includes those compositions in which the nickel content exceeds that of any other element.

Overview - EN ISO 14172:2023 (Welding consumables, covered electrodes)

EN ISO 14172:2023 specifies the classification of covered electrodes used for manual metal arc welding (MMA / SMAW) of nickel and nickel alloys. This fourth edition (2023) supersedes the 2015 edition and is the CEN-endorsed version of ISO 14172:2023. The standard covers how to identify and designate covered electrodes based on the chemical composition of the deposited all‑weld metal, and it sets the testing and documentation requirements needed for classification.

Key topics and technical requirements

Scope: Classification of nickel and nickel‑alloy covered electrodes for manual metal arc welding and overlaying (based on all‑weld metal composition).

Designation system: Product/process symbol “E” plus a chemical symbol of the form NiXXXX (four digits) indicating alloy family and specific composition; Annex A explains the designation system.

Chemical composition: Requirements for all‑weld metal chemical composition are given in Table 1. Chemical analysis is performed on suitable all‑weld metal specimens (ISO 6847 referenced).

Mechanical properties: Minimum tensile/mechanical requirements for the all‑weld metal are given in Table 2 and are mandatory for classification. Test assemblies follow ISO 15792‑1:2020 (type 1,3) using 4.0 mm electrodes.

Testing and rounding: Chemical and mechanical test methods and rounding procedures follow referenced standards (ISO 6847, ISO 15792‑1 and ISO 80000‑1:2022 rounding rules).

Additional clauses: Retests, technical delivery conditions, and designation rules are included; informative annexes describe uses and corresponding national classifications (Annexes B and C).

Practical applications and users

Classify and specify welding consumables (covered electrodes) for nickel and nickel alloys.

Support procurement and technical specifications in industries using nickel alloys (chemical, petrochemical, power generation, aerospace, marine).

Guide welding engineers, quality assurance teams, welding inspectors, manufacturers of electrodes, and procurement specialists in selecting compliant consumables.

Provide a harmonised basis for conformity assessment, supplier certification and weld procedure qualification where nickel alloy consumables are specified.
