ISO 17777:2016 prescribes requirements for the classification of covered electrodes for manual metal arc welding of copper and copper alloys. It includes those chemical compositions in which the copper content exceeds that of any other element.

Overview

EN ISO 17777:2016 (identical to ISO 17777:2016) defines the classification system for covered electrodes used in manual metal arc (MMA) welding) of copper and copper alloys - i.e., alloys where copper is the predominant element. The standard specifies how welding consumables are designated, the required chemical composition notation for the all‑weld metal, and the procedural requirements for testing and delivery.

Key Topics

Scope and purpose

Classification of covered electrodes for MMA welding of copper and copper alloys.
Applies to filler metals where copper content exceeds any other element.

Designation and symbols

Product/process symbol: E for covered electrodes.
Chemical composition symbol: Cu followed by four digits (see Table 1). Example alloy symbols in the table include Cu 6100 (CuAl8Fe3) and other Cu‑based alloy designations.

Chemical composition and analysis

All‑weld metal chemistry determines classification; specified ranges and limits are given in Table 1.
Chemical analysis is performed on appropriate all‑weld metal specimens; ISO 6847 is referenced for specimen deposition in disputes.

Rounding and test rules

Rounding follows ISO 80000‑1 rules for comparing measured values to limits.
Retest procedures: failing tests must be repeated twice; both retests must meet requirements or the material fails the classification.

Technical delivery conditions

Delivery and procurement requirements reference ISO 544 and ISO 14344.

Informative annexes

Corresponding national classifications and examples of physical properties and recommended uses of electrodes are provided (informative).

Applications

Ensure consistent classification and designation of copper alloy covered electrodes across manufacturers and purchasers.

Support quality control, acceptance testing and specification writing for welding consumables in industries using copper alloys (marine, electrical, heat exchangers, valves, and general engineering).

Guide procurement officers, welding engineers, quality inspectors, and laboratories when selecting or verifying MMA electrodes for copper and copper alloys.
