1. Laser welding : energy redistribution and weld geometry
Abstract : Over the past few years laser welding has developed into a process which has a wide range of application over a number of industries. Industrial growth in this area has been stimulated by improvements in production rates and quality but technologically the process is still not fully understood. READ MORE

2. Process chain simulation of forming, welding and heat treatment of Alloy 718
Abstract : Manufacturing of aero engine components requires attention to residual stress and final shape of the product in order to meet high quality product standards.This sets very high demands on involved manufacturing steps to meet design requirements. READ MORE

3. Conduction laser welding : modelling of melt pool with free surface deformation
Abstract : Laser welding is commonly used in the automotive-, steel- and aerospace industry. It is a highly non-linear and coupled process where the weld geometry is strongly affected by the flow pattern in the melt pool. Experimental observations are challenging since the melt pool and melt flow below the surface are not yet accessible during welding. READ MORE

4. Welding of Ti-6Al-4V: Influence of welding process and alloy composition on microstructure and properties
Abstract : Titanium alloys are widely used for components in the fan and compressor sections of aeroengines mainly because of their superior strength-to-weight ratio. Large static compressor components can be manufactured by welding together smaller subcomponents, which has potential to provide benefits such as higher buy-to-fly ratio and improved performance of the components.

5. 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
