Effect of Inhomogeneous Nugget on Weld Performance in Resistance Spot Welding of HPDC AlSi7MnMg — Part 1: Material Characterization
High-pressure die-cast (HPDC) aluminum alloys are widely regarded as a promising material for next-generation lightweight automotive structures. Compared to large, integrated die-cast bodies, adopting a modular design in which multiple small castings are joined by resistance spot welding can significantly reduce both m...
