  • Advances in Gas Metal Arc Welding and Application to Corrosion Resistant Alloy Pipes 
    da Costa Pépe, Nuno Vasco (Cranfield University, 2010-03)
    According to recent estimations, the construction of pipelines will continue to increase during the next thirty years, in particular as a result of oil and gas discoveries in remote locations. Significant advances in welding ...
  • Arc-based sensing in narrow groove pipe welding 
    Gil Teixeira Lopes, Agostinho (Cranfield University, 2006-08)
    Big gains in productivity are found in tandem and dual tandem pipeline welding but require highly skilled operators who have to control the position of the torch very accurately for long periods. This leads to high demands ...
  • Effect of welding thermal cycles on the heat affected zone microstructure and toughness of multi-pass welded pipeline steels 
    Nuruddin, Ibrahim K. (Cranfield University, 2012-09)
    This research is aimed at understanding the effect of thermal cycles on the metallurgical and microstructural characteristics of the heat affected zone of a multi-pass pipeline weld. Continuous Cooling Transformation (CCT) ...
  • High-Speed GMAW and Laser GMAW Hybrid Welding of Steel Sheet 
    Harris , I. D. (Cranfield University, 2009-03)
    Arc welding is the most widely used set of joining technologies in industry today. The automotive tier supplier network and light manufacturing are significant users of arc welding, particularly gas metal arc welding ...
  • Investigation of conduction to keyhole mode transition 
    Goncalves Assuncao, Eurico (Cranfield University, 2012-07)
    There are two very distinct welding modes in laser welding, keyhole and conduction mode. The characteristics of keyhole laser welding; mainly high penetration, high productivity and high aspect ratio have led the industry ...
  • Mechanical characterisation and modelling of resistance welding 
    Van Rymenant, Patrick (Cranfield University, 2011-07)
    Resistance welding is used very extensively in industry for a wide range of applications. Knowledge and measurement of the dynamic characteristics of resistance welding equipment is important in the design of the equipment ...
  • Real time evaluation of weld quality in narrow groove pipe welding 
    Marmelo, Patricia C. (Cranfield University, 2012-10)
    With the growth in pipeline installations all over the world, there is a great demand for highly productive and robust welding systems. Mechanised pipe welding has been developed over the last 50 years and the present ...
  • Tandem gas metal arc pipeline welding 
    Liratzis, Theocharis (Cranfield University, 2007-04)
    Energy consumption has grown by 2% per year worldwide over the past ten years. In 2005 worldwide 900,000 barrels of oil and 7.6 billion cubic metre of natural gas were produced daily. The exploitation of fields to meet ...
  • Variable polarity plasma arc welding of high strength aluminium alloys 
    Serrano, G. L. (Cranfield University, 2004-12)
    The VPP A W process has been evaluated and optimised for the joining of high strength aluminium alloys AA-2024 T351, AA-7150 W51 and AA-7150 T651. The initial experimentation was performed with conventional AC-GTAW ...
