[CN 201910523330.1] Title of a welding method for a beam on a press: Application number of a welding method for a beam on a press: CN 201910523330.1 Applicant: China Shipbuilding Industry Corporation Diesel Engine Co., Ltd. Application Date: 2019-6-17 Patent Type: Invention Application The present invention relates to a welding method for a beam on a press. The assembly process is: bottom plate is welded separately; The top plate is welded separately. The side plates are welded separately; assemble the first to fifth intermediate small pieces with the horizontal and vertical center of the bottom plate as the reference, and do tack welding without welding. Assemble the assembled first intermediate vertical plate and the second intermediate vertical plate on the bottom plate with the assembled bottom plate as the reference. Assemble the sixth to twelfth intermediate small pieces with the bottom plate with the assembled middle vertical plate as the reference, and then assemble the first side plate and the second side plate; assemble the outer parts of the side plate based on the bottom plate after assembling the side plate; assemble the top plate based on the bottom plate after assembling the outer parts of the side plate, and complete the assembly of the overall frame; after assembling the overall frame, assemble two through-bolt inner sealing plates and two through-bolt outer sealing plates, perform tack welding, and complete the welding. The whole assembly process is installed in a certain order and welding method, so that the upper beam is more stable and the tolerance is smaller.
