Abstract

The use of aluminum for car bodywork is a new trend in the automotive industry. But joining of aluminum carries a number of problems, such as pores, cracks and other internal defects. For joining of thin sheets, pressure welding is mainly used in the automotive industry. For example, spot resistance welding (RSW) or capacity discharge welding (CDW) can be used. The paper describes the influence of the parameters of CD welding on the size of the weld nuggets and the quality of the joint from the aluminum alloy EN AW 6016.
