When the welding gun 5 moves relative to the ship steel plate, the ball roller 6 moves on the ship steel plate. When the ship steel plate is an arc-shaped steel plate, when the ship steel plate is concave, the spring 3 extends, so that the welding gun 5 moves to the concave part. When the ship steel plate is convex, the spring 3 shortens, driving the welding gun 5 to move upward. The spring 3 makes the ball roller 6 always abut against the ship steel plate, so that the distance between the welding gun 5 and the ship steel plate remains unchanged, so that the quality difference of the weld is reduced, thereby improving the welding quality of the ship steel plate. Therefore, when the welding equipment for ship steel structure production is used, it can reduce the quality difference caused by the distance between the welding gun 5 and the ship steel plate, thereby improving the welding quality of the ship steel plate.
