About the 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. A far cry from its humble beginnings, the IIW membership today comprises welding associations from 56 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

The IIW is a not-for-profit organization 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.
