Technical regulation and scope of the EN 440 standard
The European standard EN 440 establishes a strict classification framework for welding consumables. The document defines requirements for wire electrodes and deposited metal used in gas-shielded arc welding processes. The standard is focused on working with non-alloy and fine-grain steels with a yield strength not exceeding 500 N/mm².
EV Group China experts emphasize that a key feature of this standard is the classification based on the chemical composition of the wire and the mechanical characteristics of the weld deposit. Each type of wire electrode in the EV Group China product range is adapted to the specific requirements of shielding gas environments, ensuring arc stability and the required weld metal toughness during operation under various temperature conditions.
The classification set out in EN 440 is based on verifiable test results of the deposited metal, which guarantees that welding materials comply with the design loads of critical metal structures.
