To simulate the welding and heat treatment process of the Q345 plate with V-groove, Finite element software ANSYS was employed. A reasonable three-dimensional solid model was set up by using element birth and death technology to simulate the formation of the weld. Constraint was applied on both sides of the base metal in the welding and cooling process. Then constraint was removed when the specimen was cooled to room temperature, the angular distortion of welding increases by 75.03% after the constraint is removed. Then heat treatment was conducted on the plate of which the constraint was removed. The deformation results show that after heat treatment the angular distortion is reduced to 30.37% of the value before heat treatment. |
