About IIW

What is IIW?

The IIW (International Institute of Welding) was founded in 1948 by the welding institutes or societies of 13 countries that considered it crucial to make more rapid scientific and technical progress possible on a global basis. The IIW membership today comprises welding associations from over 55 countries, with ever more nations continually indicating interest.

IIW’s Mission is :
  • To act as the worldwide network for knowledge exchange of joining technologies
  • To improve the global quality of life through welding

IIW’s Goals are to :
  • Identify, create, develop and transfer best practices
  • Identify, develop and implement the IIW Education, Training, Qualification and Certification systems on a global basis
  • Promote IIW and its member countries in all regions of the world to the mutual benefit of all
  • Assist in the Implementation of the IIW's outcomes
  • Assist in the formulation and preparation of International Standardization (ISO) documents
  • Provide quality services to IIW, its Member Societies and other organisations

The IIW is a not-for-profit organisation governed by the French Association law, funded by the Member Countries which pay an annual membership fee according to a scale designed to reflect, as equitably as possible, the dependence of each country on welding technology. Further income is derived from the sale of books and other documents and fees from the running of IIW Annual Assemblies and other events.
