CONTENT, ASSESSMENT AND WORKLOAD
Content
valid for whole curriculum period:
Welding technology plays a critical role in almost every industry sector - it is critical to the world's ability to cope with the continuous development demands. Whether joining the smallest bio-implants or welding the world's biggest components, welding makes significant contributions to the global quality and sustainability of life. Welding technologies, whether conventional, or advanced, and welding engineers and operators, are thus vital elements to improved quality of life for all. In fact, there is a huge demand for welders in the industry. Welding is an extremely important component of many industries in Finland and worldwide. In fact, without specialized know-how on welding, many construction projects, bridge building, vehicle manufacturing processes, computer electronics plants, plastics manufacturing, and even our space program would come to a standstill.
In the present course, the fundaments of welding and joining by fusion and solid-state are reviewed preparing the students for the introduction of the most relevant developments and recent innovations in the welding technology. The fundaments on the welding metallurgy and design of welded structures will also be assessed.
