Graduation assignment - Influence of welding cycles
The Swiss-based Allseas Group, founded in 1985 and headed by Edward Heerema, is a global leader in offshore pipeline installation and subsea construction. Allseas Engineering, located in Delft, provides project management and engineering services to other subsidiaries of the Allseas Group.
Assignment: Influence of welding cycles on fracture toughness
Modern medium/high strength steel pipeline is welded with multi-pass narrow gap automatic process, such as submerged arc welding (SAW). It is well known that the fracture toughness of medium/high strength steel weld fusion line is heavily dependent on the thermal cycles introduced by multiple welding passes. Minor variations in micro alloys in pipe base metal, welding filler wires and flux complicate the situation.
The graduation assignment comprises experimental and analytical analysis of the fusion line and heat-affected zone for a number of thermal cycles and a number of combinations of the pipe base steels and consumables.
We are looking for a student with an affinity for the correlation between theoretical models and real-world applications. In the course of this project you will develop both your engineering and your scientific skill set. The assignment requires both an analytical mind and a hands-on attitude.
This graduation assignment is available for a period of 9 to 12 months.
