| The goal | Course focused on broadening of basic understaning of welding process and weldding joints (metallurgical background, different welding processes, types and selection of filler materials, etc) and more detailed explanation of concept of crack initiation during weldingand types of cracks. | |||
| The outcome | Broadening of basic physical metallurgy phenomena during welding and methodology of selection of optimal welding technology (proces+filler material+cost) | |||
