Problems solved by technology

[0002] As we all know, when the nut is welded on the mounting plate or the mounting base plate with the installation hole, due to the relatively small welding surface, the nut cannot be reliably welded to the mounting base plate, so that in the actual use process, it often happens that the nut is removed from the mounting base plate. The phenomenon of falling off, once this nut connector is used in the key parts of the structure, unexpected accidents will occur

Abstract

The invention discloses a welding method for an embedded nut connecting piece, and by the adoption of the welding method, the nut can be reliably welded to a mounting bottom plate. The embedded nut connecting piece comprises the mounting bottom plate and a containing hole which is formed in the mounting bottom plate and matched with the nut. The welding method comprises the following steps that 1), a circle of annular trench is formed in the side face of the nut to be welded in the peripheral direction, and the distance between the lower side face of the trench and the bottom face of the nut is equal to the thickness of the mounting bottom plate; 2), the nut is put into the mounting hole of the mounting bottom plate, and at least three welding points are selected for welding with the center line of a threaded hole of the nut as the center in the circumferential direction; and 3), the welded embedded nut connecting piece is subjected to post-heat treatment. The welding method is extremely wide in application range.

Description

technical field [0001] The invention relates to a welding method, in particular to a welding method for welding a nut and an installation base plate together to form a nut connector. Background technique [0002] As we all know, when the nut is welded on the mounting plate or the mounting base plate with the installation hole, due to the relatively small welding surface, the nut cannot be reliably welded to the mounting base plate, so that in the actual use process, it often happens that the nut is removed from the mounting base plate. Once this kind of nut connector is used in the key parts of the structure, unexpected accidents will occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a welding method for the embedded nut connector that can reliably weld the nut on the installation base plate. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present inv...
