Abstract:V diplomskem delu je predstavljena enostavna merilna metoda za določitev kvalitete železnih jeder varilnih transformatorjev za uporovno točkasto varjenje. Metoda temelji na vzbujanju primarnega navitja transformatorja z napetostjo pravokotne oblike in regulacijo toka s histereznim regulatorjem. Meritve so bile izvedene na tračnih transformatorskih jedrih, tako imenovanih C-jedrih. Opazovana je bila frekvenca napajalne napetosti, ki je povezana s kvaliteto magnetnega jedra. Za potrditev rezultatov in metode je bil uporabljen Jiles-Athertonov model.
Keywords:transformator, uporovno točkasto varjenje, C-jedro, merilna metoda, Jiles-Athertonov model jedra.

Title:ANALYSIS OF TRANSFORMER IRON CORE FOR RESISTANCE SPOT WELDING
Abstract:The diploma work presents a simple measurement metod for determining the quality of iron cores of transformers for resistance spot welding. The method is based on the excitation of the primary winding of a transformer with rectangular voltage and current control with hysteresis controller. Measurements have been performed on the belt transformer cores, the so-called C-cores. Observed is the frequency of the supply voltage, which is related to the quality of the iron core. Jiles-Atherton model of the resistance spot welding transformer iron core is used to verify the results and to validate the proposed method.
Keywords:transformer, resistance spot welding, C-core, measurement metod, Jiles-Atherton core model.
