Abstract
When 0.15 percent carbon steel bars are flash-butt welded, the weld metal and heat affected zone show the widmanstätten structure and large grains.It is suitable that these parts are postheated (air cooling) at about 850°C with an electric furnace in order to change the widmanstatten structure to the annealed structure having good ductility.In the case of postheating with a flash-butt-welder, however, it is suitable that these parts are postheated at about 950°C for a short time.
