A steel sandwich sheet was produced by a high temperature dipping process. An unalloyed steel was used as substrate and an alloyed steel as coating. At the interface of the sandwich sheet a good bonding between the two different steels could be achieved by a bonding process, which was caused by the formation of a diffusion induced liquid phase. Since the bonding is connected to the formation of the liquid phase at the interface, this is similar to a conventional welding process. This welding process was investigated at the interface of well and partially bonded specimens. Based on these investigations the bonding mechanism could be explained.
