Summary: | The invention discloses a laser shock processing method for regulating and controlling residual stress of a titanium alloy panel welding joint. The method includes the steps that laser shock processing is sequentially conducted on the front face and the back face of the titanium alloy panel welding joint, wherein the direction of the laser shock processing is perpendicular to a board surface of the titanium alloy panel welding joint part, and the titanium alloy panel welding joint part and a board surface of a titanium alloy panel are located on the same plane; and in the laser shock processing process, firstly, a laser spot is made to be located on the upper end face of a welding seam of the titanium alloy panel welding joint part, the center of the laser spot is made to be located on a welding seam fusion line, and then the laser spot is made to move along the center line of the welding seam in the serpentine curve direction. According to the laser shock processing method, by adjusting the start part and th |
