ISO 2553: A useful tool for mechanical welding

ISO 2553 is known as an essential communication tool for manufacturing and assembly welders, besides being an important international industry standard for welding symbols.

Welding symbols are essential elements of industrial engineering because they establish a common language for everyone involved in the manufacturing process, from designers to factory technicians. The agreed international standards for these symbols have been updated.

If can be compared to pictographs for people who have never been in touch, welding symbols are still an essential communication tool of the manufacturing industry, allowing welders to assemble parts correctly and effective. Although there are many symbols in this area, the European system of symbols and the Pacific Rim nations are most widely used in technical drawings around the world.

By combining these two systems, ISO 2553 welding and allied processes – Symbolic symbols on drawings – Welds, has increased the rank of an important international industry standard for welding symbols. . It can show, on the technical drawings, how and where the weld must be made, by information on the geometry, manufacturing, quality and tests of the weld. This standard also facilitates comparisons between two systems as needed.

This fifth edition contains updates that allow alignment with other ISO standards related to welding and it clarifies certain complex points such as solder plugs in circular or extended holes, evaluating assemblies before welding and improving data.

ISO 2553 is prepared by ISO / TC 44 technical committee, welding and allied processes, SC 7 subcommittee, Representation and terminology, the secretariat is provided by BSI, ISO member of the United Kingdom. This standard is available from ISO members in your country or on the ISO Store.
