  • Conduction mode: broadening the range of applications for laser welding 
    Assuncao, D. E.; Ganguly, Supriyo; Yapp, David; Williams, Stewart W. (2012-11-14)
    Conduction laser welding opens up a range of innovative applications for laser welding. This relatively novel mode of laser processing expands the application potential significantly beyond what is normally achieved today. ...
  • An Integrated Approach to the Determination and Consequences of Residual Stress on the Fatigue Performance of Welded Aircraft Structures. 
    Edwards, L.; Fitzpatrick, M. E.; Irving, Phil E.; Sinclair, I.; Zhang, X.; Yapp, David (2006-02-01)
    Although residual stress in welded structures and components has long been known to have an effect on their fatigue performance, access to reliable, spatially accurate residual stress field data has been limited. Recent ...
  • Interaction time and beam diameter effects on the conduction mode limit 
    Assunção, Eurico; Williams, Stewart W.; Yapp, David (Elsevier Science B.V., Amsterdam., 2012-06-30)
    Laser welding has two distinctive modes: keyhole and conduction mode. Keyhole mode is characterized by deep penetration and high welding speeds, while conduction mode has higher quality welds with no defects or spatter. ...
  • Measuring the process efficiency of controlled gas metal arc welding processes 
    Pepe, Nuno; Egerland, Stephan; Colegrove, Paul A.; Yapp, David; Leonhartsberger, Andreas; Scotti, Ameirico (2011-07-31)
    The thermal or process efficiency in gas metal arc welding (GMAW) is a crucial input to numerical models of the process and requires the use of an accurate welding calorimeter. In this paper, the authors compare a liquid ...
  • Variable Polarity (AC) Arc Weld Brazing of Galvanized Sheet. 
    Joseph, Andy; Webb, Chris; Haramia, Mike; Yapp, David (2003-07-01)
    Requirements for improved durability in domestic consumer goods have invariably led to the application of more corrosion resistant materials. The basic material used by many industries, including automotive, ventilation ...
  • Welding with high power fiber lasers - A preliminary study. 
    Quintino, Luísa; Costa, A.; Miranda, R.; Yapp, David; Kumar, V.; Kong, C. J. (Elsevier Science B.V., Amsterdam., 2007-01-01)
    The new generation of high power fiber lasers presents several benefits for industrial purposes, namely high power with low beam divergence, flexible beam delivery, low maintenance costs, high efficiency and compact size. ...
