IIW 2019 Booklet of Awards

HENRY GRANJON PRIZE

CATEGORY B – Materials Behaviour and Weldability Dipl.-Ing. Alexander Nitsche ‘Solidification phenomena in creep resistant 9Cr weld metals and their implications on mechanical properties’

Dipl.-Ing. Alexander Nitsche (Germany) studied Mechanical Engineering at Technische Universität (TU), Chemnitz in Germany with a focus on welding and manufacturing engi- neering. In 2012 began working as a researcher in Welding Engineering at the university and successfully completed his International Welding Engineer (IWE) qualification. His work mainly comprised the investigation of heat-resistant 9% Cr steels and their welding technology. In 2018, he successfully defended his doctoral thesis, which was supervised by Prof. Peter Mayr. Nitsche is continuing his research at TU Chemnitz on the develop- ment and optimisation of heat-resistant steels and welding consumables. In addition, he is also active in student education in the area of welding and joining.

HENRY GRANJON PRIZE

CATEGORY C – Design and Structural Integrity Dir.-Ing. Jonas Hensel ‘Mean stress correction in fatigue design under consideration of welding residual stress’

2019 AWARDS FOR OUTSTANDING TECHNICAL ACHIEVEMENT

Dr-Ing. Jonas Hensel (Germany) is the Welding Division Group Leader at the Institute for Joining and Welding, Technische Universität (TU) Braunschweig, Germany. His research into residual stress-related topics includes the problem of residual stress generation in welds and residual stress relaxation, with a focus on the fatigue relevance of weld quality and post-weld treatment methods. His research group focuses on different applications of arc, resistance as well as laser and electron beam welding processes. Hensel holds a diploma in Civil Engineering from TU Braunschweig, a Master’s degree in Ocean Engi- neering from the University of Rhode Island (USA) and is an IIW IWE. He received his PhD from the TU Braunschweig in 2017 focusing on residual stress affecting the fatigue strength of welded steels. Hensel has been an active member of Commission XIII Fatigue of Welded Components and Structures since 2012.
