The galvanized steel plate is developed to protect the car from corrosion. During the resistance spot welding, the liquid metal embrittlement (LME) phenomenon occurs because of the lower melting temperature of zinc, then the melted Zn would get penetrating into the austenite grain boundaries which would cause the LME embrittlement. The high-temperature three-point tests at 600°C, 1 mm/min could be used as experimental simulation procedure. The pre-plating technology has been used to improve the LME resistance property of the galvanized steel. It could be found from the microstructure analysis that the pre-plating Ni technology could partly solve LME issue.
