1. Conduction laser welding : modelling of melt pool with free surface deformation
Sammanfattning : 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. LÄS MER
2. Contact-free surface chemistry with acoustic levitation
Sammanfattning : An ultrasonic acoustic levitator is a device that allows the implementation of contact-free studies by generating an airborne acoustic pressure field, capable of trapping, in mid-air, small volume samples (.... LÄS MER
3. Machinability of Single-phase Materials : Surface integrity and tool wear analysis
Sammanfattning : The quality and performance of products are particularly important in sectors such as research facilities and in the nuclear, military and space industries. These sectors make use of high-performance materials that are uncommon in other contexts and therefore place high requirements on personnel, machines and tools. LÄS MER
4. Torque and Angle Controlled Tightening of Bolted Joints
Sammanfattning : Reduced weight and fuel consumption, improved reliability and engine performance are the main requirements in the automotive industry of today. These requirements demand robust and optimized bolted joints, where a high amount of preload obtained by effective utilisation of the bolt is essential. LÄS MER
5. Investigation of Melt Pool Thermo-hydrodynamic Behaviour inLaser Beam Welding ofTi-6Al-4V through Numerical Simulation
Sammanfattning : Laser is an efficient and widely used heat source in metal processing suchas welding and additive manufacturing. It has some great advantages compared to the other conventional heat sources like electron beam and arc namely: ability of handling complicated joint geometries and producing large components. LÄS MER
