چکیده
In the study, effects of welding parameters on microstructure and mechanical properties electrical resistance spot welded TBF/DP600 steel sheets 1.2 mm thickness were investigated. TBF used in study was both with without electro-galvanized. Microhardness measurements tensile shear tests taken as basis determining properties, while optical microscope for microstructural characterization. The nugget size spot-welded samples determined by image processing technique, indentation depths at electrode pressure points measured ultrasonic technique. It observed from fusion zone images that two steels did not mix completely. Increasing current time increased mixing ratio zone, expanded heat affected size, depth load bearing capacity. more thermal cycle during than DP600 steel. At high input, liquid metal embrittlement based microcrack formations initiating surface galvanized observed, corrosion started rapidly region ungalvanized steels. highest hardness values ITAB side. However, a significant softening occurred transition between base capacity found to be relatively higher group. dissimilar having same thickness, lower strength has strength. input process, fractures are button type strength, partial low input. If is galvanized, obtained provide
