Summary
The course focuses on acquiring knowledge, skills, and competencies in the field of computational methods used in welding and their practical applications. Students will become familiar with methods for calculating preheating temperatures in welding, assessing susceptibility to crack formation during and after welding, and defining individual weld zones and their structural phases. Emphasis is placed on the application of the finite element method (FEM) in analyzing temperature fields in welded joints and in determining deformations and stresses in structures arising during the welding process. The course also covers the application of computational methods in the control of welding power sources, particularly pulsed, synergic, and inverter systems, as well as continuous data recording during the welding process, including subsequent evaluation and data processing.
Learning Outcomes of the Course Unit
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.
