The invention belongs to the technical field of railway vehicles, and discloses a spot welding process for the cover plate of an electric screen cabinet, which includes the following steps: S1. The cover plate is adhered to the framework of the electric screen cabinet to ensure that the conformity flatness is not more than 1 mm; S2. Setting up welding machines and auxiliary tooling for spot welding, installing the welding torch nozzle of the welding machine to the auxiliary tooling for spot welding, and setting welding process parameters of the welding machine according to the material and thickness of the cover plate and skeleton. S3. Spot welding auxiliary fixtures are positioned on the cover plate and then welded on the cover plate and the skeleton to form a weld seam. Spot welding auxiliary fixtures include fixing plates for fixing the nozzle of welding gun, and through holes are arranged on the fixing plate for penetration of the nozzle of welding gun, and supporting parts for positioning contact with the cover plate are also provided on the fixing plate. Designing spot welding assistant tooling to complete spot welding of cover plate, which reduces the deformation of cover plate, stabilizes the overall quality of the cabinet and has a good appearance. The optimum range of parameters in spot welding operation process is put forward, and the welding machine can carry out welding operation according to the relevant process requirements. The spot welding operation efficiency is high, and there is no suspicion of artificial operation difference.
