IIW C-III Intermediate Meeting 2026 in Incheon, South Korea

Successful participation in the IIW meeting in Incheon, South Korea

Incheon, South Korea - This year's Intermediate Meeting of Commission C-III (Resistance Welding, Solid State Welding and Allied Joining Processes) of the International Institute of Welding (IIW) brought together international experts in the field of resistance welding, solid-state welding and related joining processes. We were also represented on site and were able to present our current research results to a high-caliber specialist audience.

Our two lectures on the topics of "Capacitor Discharge Projection Welding of Copper and Copper-Aluminum with Multi-Pulse" held by Johannes Koal and "Magnetic Evaluation of Resistance Spot Welds for Non-Destructive Testing" presented by Christian Mathiszik met with great interest and were extremely well received by the participants. We are particularly pleased that both papers were directly recommended for publication in the renowned journal Welding in the World - a recognition of the scientific quality and relevance of our work.

In addition to the official program, the meeting offered numerous opportunities for an intensive professional exchange. The discussions were characterized by a high level of scientific depth and provided valuable impetus for future research activities and international cooperation.

A special highlight was the visit to Prof. Taeseon Lee Incheon National University. In a personal exchange, we were able to gain exciting insights into current developments in explosion welding and get to know innovative applications at close quarters in his Structural Material Processing Laboratory. The knowledge gained offers valuable starting points for our further research work and future cooperations.

We also gained exclusive insights into the production of die-cast aluminum components for electromobility at KONEC CO, LTD. Particularly impressive was the practical demonstration of friction stir welding, the industrial application of which we were able to observe directly on site. The combination of modern lightweight construction technology and innovative joining processes impressively demonstrated the potential of these technologies for future mobility solutions.

Participating in the IIW meeting in Incheon was an enriching experience for us, both professionally and personally, and underlines the importance of international scientific dialog in the field of modern joining technologies.

We would like to thank the hosts and especially Prof. Hee Seok Chang (Chairman IIW C-III) for the excellent organization of the event.
