The production technology in Ph.D study involves foundry and machining technologies, quality management and metrology, forming technology, welding and surface treatment technologies, inclusive of automation of the preparation of production as well as automation of manufacturing processes employing the above technologies. During their studies the students will get a profound knowledge of applied methematics, physical metalurgy, theory of experiments and optimization of technological processes in particular together with other theoretical and practical information closely related to the chosen field.

1. Research of the dynamics of the laser welding process

   In laser welding inside the material forms a slim cavity called keyhole. The walls are made up of liquid metal of the weld pool. Its existence is conditioned by the energy and pressure balance. Dynamics of a keyhole - weld pool can be studied only indirectly via the radiation plasma plume that form inside the keyhole and above one. The task of this work is to study the frequency and temporal characteristics of radiation at different welding conditions and bring them in connection with geometry and condition of the resulting weld. The aim of this work is the development of new diagnostic methods for monitoring the laser welding process.
