چکیده مقاله
In this study, the connection of 1050 aluminum alloy to St14 plain carbon steel was investigated by point resistance welding method The variable parameters in this processwere the holding time of the jaws and the power of the device After welding, shear tests, microstructure and microhardness tests were performed Examination of EDS analysis in the welding zone showed that the compounds formed near the steel layer are mainly ironrich intermetallic compounds and in the part near the aluminum alloy the intermetallic compounds are richer than aluminum The results of shear test showed that the highest shear strength was related to the connected sample with a power of 2 5 kV and a duration of 7 seconds in the amount of 116 60 MPa and the lowest shear strength was related to the connected sample with a power of 2 5 kV and a duration of 4 The second was 19 80 MPa The results of the microhardness test showed that the highest amount of microhardness in the welding button was related to the sample connected in 4 seconds and the power of 2 5 kW was 240 57 Vickers and the lowest amount of microhardness was related to the sample Connected in 5 seconds and a power of 7 5 kW was 165 57 Vickers Keywords: Point Resistance Welding RSW , 1050 Aluminum, ST14 Steel
