1.1 Weldability. (1)The crack. During welding, molten zinc floats on the surface of the molten pool or at the root of the weld. Since the melting point of zinc is much lower than that of iron, the iron in the molten pool will first crystallize, and the liquid zinc will infiltrate into it along the grain boundary of the steel, resulting in the weakening of the intercrystalline bond.
