Multi-Level Process Optimization of Dissimilar AA 6061-T6/ Cold-Rolled Low Carbon Steel Resistance Spot Welding via Taguchi L25: Shear Failure Force
Dissimilar aluminum to steel joints in automotive body-in-white structures fail at the weld interface because brittle Fe-Al intermetallic compounds (IMCs) form rapidly during welding and reduce joint strength. Resistance Spot Welding (RSW) can produce these joints at an industrial scale. Still, the…
