Abstract

The invention relates to the technical field of metal splicing plates, in particular to a connection auxiliary structure for a metal splicing plate, and a connection method for the metal splicing plate. The surface, facing the connection auxiliary structure, of base metal is a free surface, and a metal plate comprises an alignment surface facing the free surface; the free surface is parallel withthe alignment surface, and the distance between the free surface and the alignment surface is 0.1-5 mm; the metal plate is provided with a guide slot which is parallel with and aligned to a butt joint, and the guide slot extends toward the interior of the metal plate from the alignment surface; and the metal plate is connected the base metal through clippers. According to the connection auxiliarystructure, the metal plate is connected to the base metal through the clippers; through the set distance between the metal plate and the base metal, the allowance can be reserved for cutting a weld joint; when the metal plate is separated from the base metal, only the weld joint needs to be cut, and the reprocessing of a plurality of working procedures including repair and grinding of the free surface is avoided; and only the weld joint in the base metal needs to be ground.

Description

technical field [0001] The invention relates to the technical field of metal puzzle connection, in particular to a metal puzzle connection auxiliary structure and a metal puzzle connection method. Background technique [0002] In the field of shipbuilding, multiple pieces of base metal need to be spliced ​​and welded to form the hull. In order to obtain a weld section of normal size at the beginning and end of the welded joint, the weld is formed after welding on the butt joint, and a metal plate is assembled before welding the beginning and end of the straight butt seam like electrode arc welding, and the welding is started. The plate is called arc starting plate, and the plate used to finish welding is called lead-out plate or arc extinguishing plate, and they are cut off after use. [0003] For example, in the position of important components or sheer strakes, the sheer strakes are the side strakes connected to the strength deck (3 / 4 of the midship range), generally the ...
