【Abstract】 For continuously cast 945 steel plates the basic properties of welding joint and the toughness,fracture toughness, explosion-resistance and crack resistance of HAZ are described by using a quantity of statistical data,with an analysis of the characteristics of the steel and their effects on its weldability given. It is indicated that it is feasable and reliable to use the steel for the construction of the products, provided that the products are welded according to the basic requirements for welding processes.更多还原
