What is ISO 2560:2020 Welding consumables — Covered electrodes for manual metal arc welding of non-alloy and fine grain steels — Classification?
ISO 2560:2020 specifies the classification of covered electrodes for manual metal arc welding of non-alloy and fine grain steels.
Manual metal arc welding is a welding process that uses an electric arc between a coated electrode and the workpiece to melt the metals at the welding point. The electrode is covered with a flux that protects the weld from atmospheric contamination and provides a shielding gas to prevent oxidation.
ISO 2560 provides a system for the classification of covered electrodes based on their chemical composition, welding position, and mechanical properties. The standard also specifies the requirements for testing and acceptance of the covered electrodes.
The standard covers a wide range of electrode types, including rutile, basic, and cellulose types, and is applicable to both DC and AC welding. The classification system described in ISO 2560:2020 is widely used in the welding industry. To ensure that covered electrodes are suitable for specific welding applications and meet the necessary quality standards.
Requirements of ISO 2560:2020
Chemical Composition: The covered electrodes should have a specified chemical composition that is suitable for the type of steel being welded. The chemical composition should be indicated on the electrode packaging and should conform to the specified limits.
Mechanical Properties: The covered electrodes should have specified mechanical properties. Such as yield strength, tensile strength, elongation, and impact toughness. So, These properties should be determined through testing, and the results should be indicated on the packaging.
Welding Position: The covered electrodes should be classified according to their suitability for welding in different positions. Such as flat, horizontal, vertical, and overhead.
Coating Type: The covered electrodes should be classified according to the type of coating, such as rutile, basic, or cellulose. The coating type affects the welding characteristics of the electrode. Such as the arc stability, the ease of slag removal, and the appearance of the weld.
Diameter and Length: The covered electrodes should have a specified diameter and length. Which should be indicated on the packaging.
Packaging: The covered electrodes should be packaged in a way that protects them from moisture and other forms of contamination. The packaging should also indicate the electrode type, diameter, and length. As well as the chemical composition and mechanical properties.
At last, Testing: The covered electrodes should be tested to ensure that they meet the specified requirements for chemical composition and mechanical properties. The testing should be performed by an accredited testing laboratory. And the results should be recorded and available upon request.
Moreover, ISO 2560:2020 provides a comprehensive system for the classification of covered electrodes for manual metal arc welding of non-alloy and fine grain steels. Which helps to ensure that the welding consumables are suitable for their intended applications. Also, meet the necessary quality standards.
