21. 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.

22. Robotic Friction Stir Welding for Flexible Production
Sammanfattning : Friction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. LÄS MER
23. Feedback Control of Robotic Friction Stir Welding
Sammanfattning : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.

24. Analysis and Monitoring of Laser Welding and Surface Texturing
Sammanfattning : This thesis can be conveniently divided into three sections as follows;Part I. Monitoring of laser welding In laser materials processing there has always been a need for suitable methods to supervise and monitor the processes on-line, to ensure correct production quality or to trigger alarms when failures are detected.

25. Automatic Quality Monitoring in GMA Welding using Signal Processing Methods
Sammanfattning : An ongoing continuous process of automatization of the production lines is used in industry to reduce production costs. Automatization of quality control should be seen as part of a cost reduction process, as well as of quality control of the welding. LÄS MER
