Fatigue Strength of High Strength Steel Sheets Joined by Hemming Process

Abstract:

It is strongly desirable for the vehicle to improve passenger safety and at the same time to reduce the weight of the vehicles. A hollow section for the body structure of automobiles is studied. A high strength steel sheet is used to make the hollow sections in this studied, which are typically joined by resistance spot welding have insufficient energy absorption because the joins are not continuous. Thus, to overcome this problem, the hollow section is joined using the hemming process. The high strength steel hollow sections joined by hemming and resistance spot welding were then examined by tensile and fatigue tests. The hollow section with hemmed joins showed better performance in both tests. The overlapping joins of the hemmed hollow section have greater strength as compared to the resistance of spot welding joins.
