Learning outcomes of the course unit
The course gives the possibility to obtain the knowledge about the following technologies: metallurgy, foundry and welding of iron and non-iron materials. In each of these technologies is the attention devoted to the kind of raw materials, semi-product, melting furnaces, machinery, quality and control of processes and also to the final product. The graduate obtains the possibility of an orientation in the present (contemporary) production technologies of metals.
