Problems solved by technology

[0003] At present, in order to detect the arc welding quality of the workpiece, human eye observation or machine vision image analysis is used to evaluate the quality of the workpiece. However, the work efficiency and precision of human eye observation are low, and the machine vision image analysis takes a long time and low work efficiency. ; And after the welding is completed, the welding quality can be evaluated from the appearance of the workpiece, and the welding quality cannot be evaluated in real time

Abstract

The invention discloses an electric arc welding quality evaluation method and device and a storage medium. The method comprises the steps: acquiring a welding current signal and a welding voltage signal; according to a symbol approximate aggregation algorithm and a distance algorithm, acquiring the voltage and current distance data through the welding current signal and the welding voltage signal; inputting the voltage and current distance data into an evaluation model to obtain a welding quality evaluation label, wherein the evaluation model is obtained through training of training sample data, and the training sample data comprises training sample voltage and current distance data and a training sample welding quality preset evaluation label. According to the scheme provided by the embodiment of the invention, the electric arc welding quality can be effectively evaluated by analyzing the voltage signal and the voltage and current distance data, the data analysis amount can be effectively reduced through the symbolic approximate aggregation algorithm, the working efficiency is improved, the precision of the evaluation model is high, and the welding quality can be evaluated in real time.

Description

technical field [0001] The invention relates to the technical field of arc welding, in particular to a method, device and storage medium for evaluating the quality of arc welding. Background technique [0002] Arc welding is widely used in industrial production. The welding process is to use the metal to be welded as one pole, and the electrode as the other pole. When the two poles are close to each other, an arc is generated, and the heat generated by the arc discharge is used to melt the electrode and the workpiece and form after condensation. welded seam for a solid joint. [0003] At present, in order to detect the arc welding quality of the workpiece, human eye observation or machine vision image analysis is used to evaluate the quality of the workpiece. However, the work efficiency and precision of human eye observation are low, and the machine vision image analysis takes a long time and low work efficiency. ; And after the welding is completed, the welding quality ca...
