A comparative study has been carried out on the toughness of specimens of the C-Mn multilayer weld steel and that of the specimens simulated with the various reheating cycles by using the weld thermal-restraint stress and strain cycle simulator. It proved that the region initiating the cleavage crack, i.e., the weakest fractured at [minus]60 C([minus]76 F), is just the region having the lowest toughness among various reheated zones. The toughness of weld metal depends upon the toughness value of this weakest region. Heat input and alloying elements, such as manganese, titanium and boron, affected the toughness of weld metal by changing the toughness of the weakest region in the multilayer weldment.
