자동차용 강판의 4겹 다층 점용접물의 용접특성 평가
An Evaluation of the Weldability Characteristics on the 4 Lap Spot Welded Joint of Structural Steel Sheets in Automobile
초록
This research is conducted to investigate weldability characteristics with various welding conditions on the 4 lap spot welded joint of structural steel sheets in automobile. The relationship between the tensile-shear strength and the indentation depth has been investigated to evaluate the weldability and the optimum welding conditions. The welding current and the welding time have a greatly affect to the tensile-shear strength compared to the electrode force. It was found that the indentation depth has a relatively close relationship with the expulsion occurrence. The optimum welding conditions were proposed for the 4 lap spot welded joint.
