11. 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.

12. Laser cutting and piercing: Experimental and theoretical investigation
Sammanfattning : This thesis concerns experimental investigations of laser cutting and piercing, with theoretical and practical discussions of the results. The thesis is made up of an introduction to laser cutting and six scientific Papers. LÄS MER
13. Phenomena in material addition to laser generated melt pools
Sammanfattning : .... LÄS MER
14. Laser welding and laser heat treatment of high strength steels
Sammanfattning : Laser materials processing, including thermal treatment and laser welding has been undergoing continuous growth in the manufacturing industry for decades. A laser beam offers high precision and energy transfer, capable of various processing. LÄS MER
15. Microstructural manipulation by laser irradiation of prepared samples : The ’Snapshot Method’
Sammanfattning : Various metallurgical microstructures and their formation are studied in this thesis by using a laser beam to melt a variety of materials with different chemical compositions over a range of thermal cycles. The laser beam was used conventionally in a narrow gap multi-layer weld, used for welding large depths with filler wire additions, as well as a non-traditional simulated welding approach labelled here as the Snapshot method.
