Liquid metal embrittlementLiquid metal embrittlement (LME) is a common problem that possibly occurred in the resistance spot weldingResistance spot welding (RSW) process of the galvanized advanced high-strength steelsAdvanced high strength steel (AHSSsAHSSs). QP980 steel is widely used attributing to its excellent mechanical propertyMechanical properties. However, LME also becomes a challenge for the Zn-coated QP980 steel during the RSW process. The formation of LME cracksCrack can greatly decrease the mechanical propertyMechanical properties of the welded joint. Generally, the chemical composition of the AHSS is considered to be one of the important factors to affect the LME susceptibility. In the present study, the LME susceptibility of the RSW galvanized QP980 steels with various Si contentSi content was comparatively investigated. The results revealed that more severe LME cracksCrack could be observed in both the specimens with increasing the welding currentWelding current. In particular, the length of LME cracksCrack in the specimen with 0.849 wt% Si was much shorter than those of the specimen with 1.79 wt% Si. The comparative results reflected that lower LME susceptibility could be anticipated in the galvanized QP980 steel by reducing the Si contentSi content.
