What is BS EN ISO 21856?

When it comes to welding, it is essential to follow various standards and specifications to ensure the quality and safety of the process. One of these standards is BS EN ISO 21856, which is a comprehensive guide for welding processes, including submerged arc welding.

Submerged arc welding is a widely used welding technique that involves the formation of an arc between a continuously fed wire electrode and the workpiece. The arc is concealed beneath a layer of granular flux, which shields the molten weld pool and prevents atmospheric contamination.

BS EN ISO 21856 sets out the guidelines for selecting the appropriate wire electrodes, gases, and fluxes for submerged arc welding. It also provides guidance on the selection of wire electrodes based on factors such as base material type, joint configuration, welding position, and operating conditions.

BS EN ISO 21856 is important in various industries such as automotive, aerospace, and construction, as it ensures that welding processes meet the necessary quality and safety standards. By following this standard, manufacturers and designers can ensure that their products meet the required specifications and can provide safe and reliable welding processes.
