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. High speed imaging analysis of laser welding
Sammanfattning : Laser welding is often considered a new and exotic manufacturing method even though it has been used in industrial applications for nearly fifty years. In the early years only a few special applications justified the high investment cost involved, but as the price of the laser sources has reduced, industrial interest in laser welding has increased.

23. Optical monitoring and analysis of laser welding
Sammanfattning : After the laser was invented in 1960, it was not long until someone started using this powerful source of light to weld parts together. Laser welding became an industrial application during the 1970's and the field has developed ever since. LÄS MER
24. Technical development of the laser welding process
Sammanfattning : This thesis describes the technical development of the laser welding process and presents the results from a number of experimental investigations. The seven papers that make up the thesis investigate various aspects of the technical development of the laser welding process mechanism as well as industrial applications. LÄS MER
25. Analysis of laser arc hybrid welding experiments
Sammanfattning : The thesis is about the analysis of experimental results on the laser arc hybrid welding (LAHW) process as well as about the methodology and tools behind. Due to the high potential on weld penetration and welding speed, the industrial importance of LAHW techniques has been increasing in the recent years. LÄS MER
