The present application relates to the technical field of shipbuilding, and discloses a welding method for a ship platform plate and an outer plate, which comprises the following steps: S1, measuring the thickness t of the platform plate; S2, butting the platform plate and the outer plate, with the outer edge of the lower end surface of the platform plate being connected to the outer plate; S3, measuring the maximum gap G between the inner side wall of the outer plate and the outer edge of the upper end surface of the platform plate and the included angle θ formed between the inner side wall of the outer plate and the lower end surface of the platform plate; S4, cutting the outer edge of the platform plate under the conditions of the thickness t, the maximum gap G and the included angle θ; S5, abutting the platform plate and the outer plate, with the first welding position being formed between the inner side wall of the outer plate and the outer edge of the upper end surface of the platform plate and the second welding position being formed between the inner side wall of the outer plate and the outer edge of the lower end surface of the platform plate; S6, opening a groove on the first welding position; and S7, sequentially welding along the first welding position and the second welding position to form the first weld and the second weld respectively. The welding method for the ship platform plate and the outer plate can reduce the workload of welding and ensure the welding quality.
