Study on Welding Process of Grade 460 MPa High Strength and Toughness Marine Steel Plate
The submerged arc welding and vertical gas electric vertical welding tests of 460MPa high strength and toughness marine steel plate are carried out.The results show that when 460 MPa high strength and toughness marine steel is welded under the conditions of heat input of 50 kJ/cm,80 kJ/cm and 200 kJ/cm,the tensile and impact properties of the welded joint are good,which meets the requirements of classification society,indicating that the steel has good weldability and is suitable for high heat input welding.
