IIW in short

The International Institute of Welding (IIW) is recognised as the largest worldwide network and centre of reference for welding and allied joining technologies.
It operates as the global body for the science and application of joining technologies, providing a forum for networking and knowledge exchange among scientists, researchers and industry, and disseminating leading edge research results and best practices.

  • Through the work of its Technical Working Units, the organisation'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 microjoining and additive manufacturing. IIW work also embraces allied fields including quality assurance, non-destructive testing, standardization, inspection, health and safety, education, training, qualification, design and fabrication.
    - The IIW is a standardising body approved by the International Organization for Standardization (ISO) to develop standards in the field of welding and related processes.
    - IIW’s Technical Database constitutes the world’s largest online resource for welding information available today. The most outstanding papers are published in the prestigious journal ‘Welding in the World’ registered in Thomson Reuters Science Citation Index® since 2009

  • IIW International Education, Training Qualification and Certification Programmes for welding personnel and companies are recognised worldwide.
    The systems developed for education and training are paving the way towards one global education and qualification system for welding personnel.

IIW organisation is built on these two branches :
