Abstract

When welding a zinc coated steel sheet, the associated thermal cycle may activate diffusion and/or alloying reactions between steel and zinc. These reactions develop differently depending on the coating type (electro- or hot dip-galvanized, galvannealed). This in turn determines the chemical aggressiveness of the coating toward its environment, for example the copper electrodes used in spot welding.
