The need for lightweight, fuel efficient vehicles is becoming increasingly common in the automotive industry. The implementation of advanced high strength steels (AHSS) and aluminum alloys to body in white designs promote the ability to use materials with better strength to weight ratios than previous generation materials. Resistance spot welding AHSS to Al brings forth its own set of challenges but the ability to use new techniques can help improve the weldability issues of these joints. This two-part study investigates the use of interlayer technology to improve the weldability and mechanical performance of AHSS-AHSS and AHSS-Al joints. The interlayer deposition, RSW parameters and mechanical performance of these joints will be presented.
