Drawn arc stud welding: Crossing over from steel to aluminum

In their quest to reduce vehicle weights, car manufacturers are exploring further use of aluminum, including more aluminum components in body construction. To acquire a better understanding of aluminum stud welding, auto manufacturers worldwide have formed a task force to conduct research on aluminum joining methods. Currently, Emhart Fastening Teknologies is working with this group in development programs such as Earthing studs, WELDFAST and Self-Pierce Rivet (SPR). The global automotive industry is clearly committed to the increased use of aluminum in cars and trucks. This presents enormous challenges and responsibilities for assembly systems suppliers, particularly those specializing in welding processes. Continuing strides in the technological sophistication of DASW is bringing this process to the forefront in advancing the use of aluminum in vehicles throughout the world.
