1. Gas Metal Arc Melt Pool Modelling : Effect of welding position and electromagnetic force mode
Sammanfattning : 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. LÄS MER
2. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation
Sammanfattning : 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. LÄS MER
3. Modelling of cathode-plasma interaction in short high-intensity electric arc : Application to Gas Tungsten Arc Welding
Sammanfattning : In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. LÄS MER
4. Modelling of Electric Arc Welding : arc-electrode coupling
Sammanfattning : 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. LÄS MER
5. Novel beam shaping and computer vision methods for laser beam welding
Sammanfattning : Laser beam welding has been widely applied in different industrial sectors due to its unique advantages. However, there are still challenges, such as beam positioning in T-joint welding, and gap bridging in butt joint welding,especially in the case of varying gap width along a joint. LÄS MER
