This course introduces Liquid Metal Embrittlement (LME) as a key challenge in resistance spot welding of zinc-coated advanced high-strength steels (AHSS). It explains its causes, contributing factors, and impact on material performance, while outlining four practical steps to mitigate LME through improved material selection, testing methods, and optimized welding practices.
