The welding operations were performed with different welding currents (10 kA, 12.5 kA and 15 kA), welding times (10, 15 and 20 cycles) and electrode forces (5 kN, 10 kN and 15 kN) by electrical resistance spot welding. The welding nugget diameter, electrode immersion depth, hardness and tensile-shear test results of the welded samples were examined and the mechanical properties were compared. As a result of the tests, it was seen that the welding parameters had a greater effect on the mechanical properties of the IF 180-5754 Al alloy welding pair than the IF 180 - Ti-Gr2 alloy pair. It has been determined that the welding current and electrode force significantly affect the nugget diameter, electrode immersion depth and the maximum tensile force in both welding pairs.eninfo:eu-repo/semantics/closedAccessMechanical-propertiesDissimilar materialFailure modeMicrostructureStrengthJointsWeldabilityParametersTensileTimeIf180Titanium gr25754 al alloyResistance spot weldingMechanical propertiesScience & technologyTechnologyEngineering, multidisciplinaryEngineeringArticle000581901200007100310132342147-9429
