Summary
Basic subject for Master's degree, focused on welding. Students become acquainted with the principle of the welded joint creation during fusion and solid-state welding and with the importance of thermal cycles and their influence on the structure and properties of welded joints. The course contains basic principles of cracks creation in welded joints and theoretical knowledge about the weldability of different types of materials. Subject included also theoretical background of soldering and brazing. Students will also be informed about welding of heterogeneous materials, welding of cast irons and cast steels, non-ferrous metals and plastics.
Learning Outcomes of the Course Unit
The aim of the object is to provide students with the complex professional information about the theoretical principles of welded joints formation at fusion and pressure welding, physical principles of the metal welding processes, metallurgical behavior between weld metal and slag or shielding gases, weld metal formation and weld metal crystallization principles, phase transformations in the weld joints, weld joints cracking phenomena, deformation and tension processes in the welds, materials weldability and theoretical principles of materials brazing. Based on the received information the students will be able to independently professionaly solve the task in the technical activities in the field of welding.
Course Contents
Basic subject for masters (engineering) study "Mechanical engineering" with
concentration on welding. Table of contents of the subject are physical,
chemical and metallurgical processes influence weldability of materials,
properties of welded joints and formation of defects in welded joints. Subject
inluded also theoretical background thermal cutting, soldering and brazing of
materials. The students will also in the subject inform about
weldingheterogeneous materials, cast iron and cast steel, non-ferrous metals
and plastic matters.
