| Abstract Scope |
There has been an increase in the implementation of advanced materials in the construction of vehicle structures for the automotive industry due to the need for vehicle lightweighting. The joining of these vehicle structures is primarily completed using resistance spot welding (RSW) due to factors such as its increased efficiency and process control. By using this process, multi-material structures are joined that are meant to have increased strength, great crashworthiness, and are lightweight. Advanced high-strength steels (AHSS) and aluminum alloys are commonly joined together to address these goals but have a greater level of complexity when compared to conventional RSW. Dissimilar welding between AHSS and aluminum can be challenging due to the metallurgical incompatibility between the materials. This study uses a novel interlayer approach to improve the weld quality while examining intermetallic (IMC) formation and interlayer deposition methods such as ultrasonic metal welding (UMW) and laser powder bed fusion (LPBF). |
