Contact Dr Paul Colegrove

Areas of expertise


After working for a few years in the steel industry and then as a consultant Paul obtained a PhD from the University of Cambridge in 2004 on modelling of Friction Stir Welding.  Following a short post-doctoral research post in Cambridge, Paul became a lecturer and then Senior Lecturer at Cranfield University.  He has developed expertise in a number of key areas including the use of deformation methods to control residual stress and distortion in welded joints; the application of cold work methods during Wire + Arc Additive Manufacture for microstructural refinement; development of a laminar flow shielding device for WAAM that avoids deposition within a chamber; fundamental studies on plasma deposition and arc physics; and numerical modelling of friction-based processes.  He has over 78 publications including 54 in journals and four book chapters.  Finally he has run the MSc course on Welding Engineering for 9 years, teaching four of the modules and supervising a large number of projects.  This course has grown considerably over this period and is well regarding nationally and internationally – educating the next generation of Welding Engineers.
