Resistance spot welding technologies of high strength steel (HSS) sheets were investigated in order to get high reliability in welded-joints of automobile components. Suitable welding current range shifted to lower currant side by the effect of electric resistance increase of steel sheet and the width of this range was affected by electrode force. Vickers hardness [...]

A well-established knowledge of the fractographic characteristics of cast alloys is required to perform fracture analysis of failed components and to determine their fracture mechanisms. It can also be used to validate related claims on car insurance coverages. These analyses contribute to the continuous improvement of the production process and product design. This paper presents [...]
