IIW

IIW is an acronym that can refer to different organizations and events. The two most widely recognized uses are the Internet Identity Workshop and the International Institute of Welding.

The Internet Identity Workshop is an annual, participant-driven forum focused on digital identity, privacy, and interoperability. It brings together developers, researchers, advocates, and vendors to discuss open identity standards and practical implementation. While not a formal standards body, IIW has helped advance discussions on identity technologies such as decentralized identity, user-centric authentication, and interoperability among identity systems. Topics commonly addressed include identity on the web, consent, privacy, and governance.

The International Institute of Welding is a global federation of national welding associations that coordinates welding research, education, standards development, and professional training. It publishes technical reports and documentation and organizes congresses and meetings to promote welding technology worldwide. As a professional organization, it serves engineers, researchers, and educators involved in welding and fabrication.

Because IIW can refer to multiple entities, the intended meaning depends on the context. In technical or industry discussions, IIW most often points to one of these two organizations, though other uses may exist in different fields.
