Vahid Hosseini is a professor of welding technology in the Department of Mechanical and Industrial Engineering. His teaching and research focus on understanding how welding and additive manufacturing processes influence the microstructure and performance of high-performance alloys such as high-strength steels, stainless steels, aluminium alloys, and superalloys.

Background

Vahid earned his B.Sc. in Industrial Metallurgy from Iran University of Science and Technology and his M.Sc. in Welding Technology from Sharif University of Technology, before working in the power generation and steelmaking industries. In 2014, he moved to Sweden to complete a Ph.D. at University West, where he studied welding and processing of duplex stainless steels and later worked as a postdoctoral researcher and assistant professor. From 2021 to 2025, he was with ESAB, a global leader in welding equipment, where he managed research projects and led a research team.  

NTNU welding Lab

NTNU has an equipped welding lab. We have:  

• 3 fully robotic welding cells with 2 Fronius TPS 400i welding machines and a TIG welder. 
• 16 kW ytterbium fiber laser (IPG Photonics YLS-16000-S2 type model)
  •  HYBRID Laser-GMAW capability
  • This equipment is shared with SINTEF
• Friction stir welding from STIRWELD.
• A few other welding machines for educational purposes.

Of course, we have access to other labs for materials characterization and testing, where NTNU has state-of-the-art equipment.
