Abstract

The tensile properties,impact toughness and hardness of the welded joints of DP590 low-cost hot rolled dual phase steel using appropriate welding wire,flux and reasonable welding process was studied. The excellent softening resistance,cold bending formability and low hardening tendency of the test steels was shown. Experimental results showed that the DP590 low- cost hot rolled dual phase steel with good welding performance was suitable for welding car wheels and beams,etc.
