The research question for this PhD has direct link with industry and is 'how to join high integrity multi-material joints in a way suitable for a low cost high volume car production line?'
At the moment resistance welding is traditionally the technique of choice for thin metal joining in the automotive industry. Over the last century mass production of cars has been enabled as a result of high speed, reliable, easily automated joining of low carbon steels using the resistance spot welding process.
The key objective of the work of this PhD is to develop novel methods and solutions to allow the new generation of materials to be joined by the resistance welding process. The bulk and surface properties of the materials to be joined will be studied; the mechanical properties of the joints will be assessed against industry requirements. New innovations will look at methods to produce reliable joints in a wide range of steel to aluminium joint combinations. Optimum solutions will be fast, repeatable and low cost.
