Galvanized steel components should not be welded to ________ due to LME.

Question

Quizplus · Accepted Answer

Galvanized steel components should not be welded to 300 Series SS due to the risk of liquid metal embrittlement (LME). LME can occur when dissimilar metals are welded together and a liquid phase forms during welding. This liquid phase can penetrate into the grain boundaries of the base material and cause embrittlement, which can lead to cracking and failure of the joint. 400 Series SS, carbon steel, and Duplex SS do not pose as high a risk for LME when welded to galvanized steel components.
