مقاله جوشکاری با عنوان :Welding time effect on mechanical properties of automotivesheets in electrical resistance spot weldingS. Aslanlar a,*, A. Ogur b, U. Ozsarac a, E. Ilhan a چکیده:In this study, the effects of welding time on the tensile-peel strength and tensile-shear strength of welding joints in electrical resistancespot welding of chromate micro-alloyed steel sheets having 1.2 mm thicknesses were investigated. A timer and current controlled electricalresistance spot welding machine having 120 kV A capacity and a pneumatic application mechanism with a single lever was used toprepare the specimens. Welding current periods of 5–10 kA and 12 kA were selected, and it was adjusted by increasing 5 cycle from 5cycle to 15 cycle during the welding process. The electrode pressure was fixed at 6 kN. The welding joints were exposed to tensile-peel andtensile-shear tests, and the effect of welding time on tensile-peel strength and tensile-shear strength was researched by using related perioddiagrams. The optimum welding times were obtained.
