| description | In the article the R65 type rail joints that were welded by resistance welding are analysed. Survey methodology of the research consists of the following parts: visual inspection of welded joint, ultrasonic rail inspection, hardness test of upper part of the rail, fusion area research, the measurement hardness test of heat-softened area, the measurement microhardness test, microstructure research of the welded joint, impact strength experiments, chemical analysis of welded joint, wheel-rail interaction research using the finite element method (FEM). The results of the research are analysed and the quality of weld is evaluated. The conclusion is based on the results of this research.

Straipsnyje nagrinėjama R65 tipo bėgio kontaktinio suvirinimo jungtis. Atlikti svarbūs tyrimai, kuriuos sudaro šios dalys: apžiūrimasis paviršiaus tyrimas, ultragarsinės kontrolės tyrimas, važiuojamasis paviršiaus kiečio bandymas, sulydimo zonos nustatymas, termiškai suminkštintos zonos kiečio matavimas, mikrokietumo matavimas, mikroskopinis jungties matomosios terminio poveikio ir sulydymo zonų tyrimas, smūginio tąsumo bandymas, cheminė analizė, aširačio bandažo ir bėgio sąveikos tyrimas baigtinių elementų metodu (BEM). Išanalizuoti gauti tyrimo rezultatai, kuriais įvertinama suvirinimo siūlės kokybė. Pateiktos tiriamojo darbo išvados.
Reikšminiai žodžiai: kontaktinis suvirinimas; bėgiai; ardomoji ir neardomoji kontrolė; jungties defektai. |
