Abstract. Liquid Metal Embrittlement (LME) cracking is a well-documented issue encountered during resistance spot welding (RSW) of zinc-coated advanced high-strength steels (AHSS) in automotive manufacturing. Given that existing research has predominantly focused on laboratory-scale samples and lacks investigation into the load-bearing capacity joints under crash conditions, this study aims to fill these gaps by analyzing third-generation AHSS. S-Rail components were produced through...
Liquid metal embrittlement (LME) cracking is a phenomenon observed during resistance spot welding (RSW) of zinc−coated advanced high−strength steels (AHSS) in automotive manufacturing. In this study, severe cracks are at the edge sheet under reduced flange widths. These cracks, traversing AHSS sheet, culminate with width approximately 1.2 mm. Through combined numerical and experimental investigations, material testing, these identified validated as new type LME crack. The mechanism behind...
