1. Modelling of Electric Arc Welding : arc-electrode coupling
Abstract : Arc welding still requires deeper process understanding and more accurateprediction of the heat transferred to the base metal. This can be provided by CFD modelling.Most works done to model arc discharge using CFD consider the arc corealone. READ MORE

2. Gas Metal Arc Melt Pool Modelling : Effect of welding position and electromagnetic force mode
Abstract : Gas metal arc is a high-efficiency and widely used heat source for metal processing applied predominantly in welding and additive manufacturing. In this study, it was applied to welding. READ MORE

3. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds
Abstract : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. READ MORE

4. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation
Abstract : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. READ MORE
