Subject aims expressed by acquired skills and competences
The graduate will acquire the knowledge, skills and competences in the field of computational methods in the fields of welding and their use.
The aim of the study is to obtain knowledge of numerical methods in welding in the areas of:
-calculations preheating in welding
-calculations on the vulnerability in the cracks and after welding
-calculations when you define each area of the weld and their structural phases
-calculations using finite element methods (FEM) for the monitoring of temperature fields in the fields of welded joints
-calculations using finite element methods (FEM) for the determination of deflection and stress in welding in building construction
The second group is the management of the application of computing methods of welding sources, in particular in the areas of pulse, synergy and inverter resources.
A third group of application of computing methods in welding is a continuous record of data in the process of welding, their subsequent evaluation and processing.

Summary
The graduate of the course acquires knowledge, skills, and competencies in the field of computational methods used in welding and their practical applications. They are familiar with methods for calculating preheating in welding, are able to assess susceptibility to crack formation during and after welding, and understand procedures for defining weld zones and their structural phases. They master the principles of using the finite element method for the analysis of temperature fields in welded joints and for determining deformations and stresses arising in structures during welding. At the same time, they understand the application of computational methods in the control of welding power sources, particularly pulsed, synergic, and inverter systems, and are familiar with the continuous recording, evaluation, and processing of data during the welding process. The acquired knowledge is applied in the analysis, optimization, and control of welding processes in engineering practice.
