1. Aspects of Heat Flow in Laser Processing of Metals
Sammanfattning : Since the laser was invented in 1960, its use in manufacturing industry has been growing rapidly. Laser processing of metals is based on the flow of heat that is generated by the absorbed laser beam. LÄS MER
2. 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
3. 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.

4. Interaction mechanisms for a laser-induced metallic boiling front
Sammanfattning : This thesis is about fundamental interaction mechanisms of laser remote fusion cutting, RFC, which is based on the formation of a quasi-stationary laser-induced boiling front that causes drop ejection, preferably downwards. Laser cutting of metals, invented in 1967, has developed from a niche to a well established high quality cutting technique in the manufacturing industry. LÄS MER
