摘要：
Effects of steel coatings on weldability in resistance spot welding of galvannealed steel sheets were investigated. The steels with different coatings, where Fe content changed from 7.0 wt% to 11.4 wt%, were welded by alternating current (AC) welding machine. The results showed that the weldability in RSW of the GA steel with 11.4 wt% Fe was the best in three researched steels. Higher Fe content in the coating resulted in increased contact resistance and hence reduced welding current needed and increased the range of weld current in RSW.
