- Selection of weld head and source for different applications.
- Optimization of the welding cycle parameters (squeeze, welding and forge pressure, current, welding time, number of cycles) for different applications. Definition of operating windows.
The resistance welding technology is based on the formation of a welding spot or seam by the fusion and coalescence of two metallic surfaces. Contacting parts are joined by the heat obtained from resistance to eletric current and the application of pressure. Electric power sources are used to generate high intensity electrical currents (thousands of amperes) and electrodes through which that current flows.
Noteworthy advantages of this technology are high energy efficiency, low part deformation, remarkably high production rates, easy automation and absence of filler metal.

PhD in Science by the University of Navarra. He has been a researcher in the Processes area since 2007. He is specialized in metallurgy and weldability, welding technologies (arc, laser, resistance, friction-stir, cracking), cladding, and additive manufacturing processes. He has good communication skills in Basque and English (CAE certificate), full commitment and passion for research, continuous learning and business development.In November 2018, he received recognition from the Basque Government as top researcher for his research work and scientific-technological merit.
He has led different European projects (2) and participated in others as researcher (7). At a national level, he has participated in more than 60 basic research, and applied research and innovation projects with companies. He has participated in numerous international conferences related to additive manufacturing and joining technologies (more than 30) and he is the author of 29 indexed scientific articles which have been referred 356 times.
He is a member of the Spanish AEN/CTN 14 Technical Standardization Committee. He is teacher and coordinator International Welding Engineer course (IWE) and of the Master’s Degree in Industrial Additive Manufacturing (University of Mondragon).
He is currently leader of research projects related to advanced joining technologies, and additive manufacturing of metal components. He is a LORTEK delegate on the European platforms, AM Platform and Joining Platform.
