Please note! Course description is confirmed for two academic years (1.8.2018-31.7.2020), which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.
LEARNING OUTCOMES
After the course the student can:
-Identify the main joining mechanisms within welding technology;
-Address the fundaments of physics of electric arc and metallic transference in electric arc welding;
-Implement an applicability analysis of SMAW + SAW + GTAW + PAW + GMAW + FCAW + LW + EBW + Hybrid joining techniques
-Address the fundaments of solid-state welding techniques and joining techniques for advanced materials: polymers; ceramics; composites;
-Make a weldability analysis based on the welding metallurgy;
-Apply the fundaments of design of welded structures with a focus on static loading conditions

CONTENT, ASSESSMENT AND WORKLOAD
Content
Valid 01.08.2020-31.07.2022:
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.
