Performance prediction method for weldment

Abstract

The embodiment of the invention relates to the technical field of welding, and discloses a performance prediction method for a weldment. According to the method, a target welding wire of a corresponding specification is determined according to to-be-simulated pseudo soldering parameters, and the to-be-simulated pseudo soldering parameters are used for representing the to-be-simulated pseudo soldering degree; welding the part by using a target welding wire; and detecting and analyzing performance parameters of the part welded with the target welding wire in a working state. In the future, the performance of the assembled part is detected. According to the method, whether the assembled part has the pseudo soldering problem and the pseudo soldering degree can be determined according to the corresponding relation between the analyzed performance result and the pseudo soldering parameters to be simulated, the pseudo soldering detection process is simplified, the judgment result is preventedfrom being influenced by external factors such as the welding position, and the pseudo soldering defect is judged more accurately.

Description

technical field [0001] The embodiments of the present invention relate to the field of welding technology, in particular to a method for predicting the performance of welded parts. Background technique [0002] When welding metal components, a certain amount of energy, such as temperature, infrared light, laser and other energy, is usually applied to the welding site. In this way, the atoms in the welded part where the energy is applied diffuse, and when the atoms diffuse into the adjacent metal device, they can form an intermetallic compound with the adjacent metal device, thereby using the force of the chemical bond to make the metal component and the adjacent metal device The metal components are connected, that is, the welding of the metal components is realized. [0003] In practical applications, if the energy of the welding part or other parameters are not selected properly, the thickness of the intermetallic compound generated at the welding part will also be differ...

Problems solved by technology

However, the related technology detects the welding area. Since the position of the welding area is not fixed, when the position of the welding area is irregular or it is difficult to observe the welding effect, it is easy to cause inaccurate measurement results.
