The development of new approaches in image processing and retrieval provides several opportunities in supporting in different domains. The group of welding engineers frequently needs to conduct visual inspections to assess the quality of weldings. It is investigated, if this process can be supported by different kinds of software. A generic CBIR system has been successfully used to sort welding...

The paper deals with the analysis of influence parameters resistance spot welding. Resistance welding is high-efficiency process for joining metallic materials. application still most used method car body parts. was determined by an experiment. optimal achieving highest load-bearing capacity joints material TRIP40 / 70 a defined thickness 0.77 mm were determined. results reached values from 630...

This paper explains an integrated method of using genetic algorithm on the experimental data for optimizing the process parameters for height to width ratio and use of artificial neural network techniques for predicting the effects on the four weld bead geometric descriptors (front height, front width, back height and back width) by the five controlling weld process variables (welding speed, wi...

An effective and rigorous approach to determine optimum welding process parameters is implementation of advanced computer aided engineering (CAE) tool that integrates efficient optimization techniques and numerical welding simulation. In this paper, an automated computational methodology to determine optimum arc welding process control parameters is proposed. It is a coupled Genetic Algorithms ...

According to structural characteristics of the parts for the power battery, a structural model of clamp welding head basing on the loop sensor principle is established by means of PRO/E in this article, and a newly power battery spot-welding maching was research. It had some functions of the data’s input and modification, controlling of welding worktable, spot-welding mechanism adjusting initia...

The in-process changes of weld nugget growth during the Resistance Spot Welding were investigated based on the resistance of input electrical impedance. To compute the time varying resistance of input electrical impedance, the welding voltage and current signals are measured simultaneously and then converted into complex-valued signals by using Hilbert transform. Comparing with the dynamic cont...
