The Investigation of Mechanical Properties of the Flash Welded Different Steel Bars
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 4
Abstract
In this study, three type steel bars were selected as experimental specimens. The steel types are S235JR (St37), S355JR (St52), AISI 304 stainless steel. Experimental parameters are material type and weld current. The specimens which have Ø24 x 200 mm dimensions flash welded both each other and different steel bars as using three weld currents. After the welding operations, the welded specimens were cooled at open - air conditions and their diameters were dropped by using a lathe machine so that the tensile tests can be applied to them. Micro Vickers hardness tests and tensile tests were performed each center of the welded specimens and around the weld zone. According to results, it was not seen that change in welding current has a direct effect on hardness and the highest hardness value was seen in St52-St52 sample. It was seen generaly increase in welding current negatively effected breaking strenght and least effected welded samples by tensile strenght welding current were St37-St37, AISI304-AISI304. The results are given as Figures and discussed.
