FARHANG FARROKHI DEFENDED HIS PH.D. THESIS ON ‘HYBRID LASER WELDING OF LARGE STEEL STRUCTURES: AN EXPERIMENTAL ANDNUMERICAL STUDY’
Farhang Farrokhi’s thesis investigates two different challenges related to the hybrid laser welding of thick-section steel plates. Employing empirical and analytical approaches, his thesis attempts to provide further knowledge towards btaining quality welds in the manufacturing of large steel structures.
Abstract: Manufacturing of large steel structures, e.g. offshore wind turbine foundations, requires the processing of thick-section steel plates. Welding is one of the main processes during the manufacturing of such structures and includes a significant part of the production costs. Taking the advantage of hybrid laser welding technology using high-power lasers, potentially allows lowering the manufacturing costs of offshore wind turbines, and consequently, more competitive prices for wind energy. However, hybrid laser welding is a complicated process that involves several complex physical phenomena that are highly coupled. Understanding of the process is very important for obtaining quality welds in an efficient way.
Congratulation on the defence!
However, this is not a goodbye. We are very lucky that Farhang is continuing at the department as Postdoc!
