This work is dedicated to the evaluation of the welding process in terms of assessing the impact of weldability based on the recording of the non-destructive testing of the acoustic emission (AE). Measurements are performed utilising both materials with guaranteed weldability and materials with reduced weldability. In addition to welding, the thesis also discusses the material (metallographic and fractographic) and mechanical verification of joint formation and the variations in behaviour of metals of differing chemical composition. It also includes an analysis of AE records in relation to the condition of the material during the developing of fusion and resistance joints.

Keywords: welding, weldability, acoustic emission, defects of weld
Grants and funding:

The research has been supported by the project IP 10/2015 "Degradation properties of welded joints" financed by IGA AF MENDELU. This work is an output of research and scientific activities of NETME Centre, regional R & D centre built with the financial support from the Operational Programme Research and Development for Innovations within the project NETME Centre (New Technologies for Mechanical Engineering), Reg. No. CZ.1.05/2.1.00/01.0002 and, in the follow-up sustainability stage, supported through NETME CENTRE PLUS (LO1202) by financial means from the Ministry of Education, Youth and Sports under the "National Sustainability Programme I".
