The International Institute of Welding

The International Institute of Welding (IIW) was founded in 1948 by the welding institutes/societies of 13 countries who considered it crucial to make more rapid scientific and technical progress possible on a global level.

Their vision was for the IIW to be the international vehicle by which innovation and best joining practices could be promoted, while providing an international platform for the exchange and dissemination of evolving welding technologies and applications.

From its humble beginnings, the IIW is today a universal reference, recognized as the largest worldwide network for welding and allied joining technologies, boasting a current membership of 59 countries from five continents.

The IIW's Mission is to operate as the global body for the science and application of joining technology, providing a forum for networking and knowledge exchange among scientists, researchers and industry. Through the work of its 26 Technical Commissions and Working Units, the organization's technical focus encompasses the joining, cutting and surface treatment of metallic and non-metallic materials by such processes as welding, brazing, soldering, thermal cutting, thermal spraying, adhesive bonding and microjoining.

IIW work also embraces allied fields including quality assurance, non-destructive testing, standardization, inspection, health and safety, education, training, qualification, design and fabrication.

In 1986, IIW was selected as one of the world’s three official International Standardizing Bodies in the areas of welding and joining. Since the date, the organization, together with the practical input of industry leaders, has published eighteen international welding standards under the auspices of the International Organization for Standardization (ISO). The standards programme covers materials, test methods, best practices, new technologies, health and safety matters, environmental issues and management. With the qualification of welding personnel now mandatory for manufacturers everywhere, IIW has established a requirements system for the proper education, training, qualification and certification of welding professionals, from engineers and technologists to on-site practitioners. These standards enable countries to shape qualified, world-class professionals locally, thus making welding one of the only professions to have uniform requirements around the world.

IIW’s virtual library constitutes the world’s largest online source of welding information available today. Members can consult and share technical documents, white papers, publications, articles and original doctoral theses not found elsewhere… comprising a database of roughly 20,000 documents, of which more than 1,000 may be downloaded from the IIW web site. And for in-print access to the latest, most significant findings of researchers and practitioners from around the globe in brief, the IIW journal, “Welding in the World”, is published six times yearly and may also be consulted online.
