Svařování pozinkovaných a austenitických plechů v sériové výrobě

Abstract

The master thesis deals with the evaluation of the quality of a welded component. The weldment consists of austenitic and galvanized plate and it is made using the method of point resistance welding. The task of master’s thesis was to optimize the welding process in order to minimize the number of defects. The theoretical part is characterized by resistance spot welding and its effect on the weldability of these steels. Experimental part is divided into two parts. The first part is characterized by an initial state welding defects and samples. The second part focuses on the setting of new welding parameters and subsequent evaluation of the quality of the welds. In conclusion, the proposed procedure for testing the quality of weldments nondestructive examination and possible further optimization practices.
