Novel Control Techniques For Co2 Shielded Gas Metal Arc Welding, Dominic Cuiuri, John Norrish, Christopher David Cook Jan 2003

Novel Control Techniques For Co2 Shielded Gas Metal Arc Welding, Dominic Cuiuri, John Norrish, Christopher David Cook

Faculty of Engineering - Papers (Archive)

The control strategies that have been developed over the past four decades to control the inherently unstable metal transfer in the CO2-shielded GMAW process are described. The fundamental reasons for poor arc stability with CO2 as a shielding gas are discussed. From an understanding of the process behaviour, a new process control technique is proposed, and the future direction of research in this area is discussed.


Australian Transport And Greenhouse Gas Reduction Targets, Philip G. Laird Jan 2003

Australian Transport And Greenhouse Gas Reduction Targets, Philip G. Laird

Faculty of Engineering and Information Sciences - Papers: Part B

Transport greenhouse gas emissions have increased by about 24 per cent since 1990-91 making transport the fastest growing contributor of all sources of greenhouse gas emissions in Australia. This paper compares the energy efficiency of different modes of transport for freight and passenger tasks. If demand for road vehicle travel was managed and growth in passenger and freight tasks was picked up by the more energy efficient public transport and rail, Australia would begin to reduce its greenhouse gas emissions and move closer to achieving its greenhouse gas target.
