Abstract

As already known, no proper control or process control parameter which absolutely guarantees a high level quality of joints made by electro-resistive welding has been established so far, especially when all possible parameters are taken into account during the welding process. Due to the process of butt-welding being very short-lived, ensuring quality of the joints is a difficult and under-researched problem. The application of non-destructive testing methods to the control interface joints is also not reliable. Therefore, further research in this area should concentrate on studying the influence of basic welding parameters, and calculating their direct or indirect impact can serve to achieve a highquality welded joint with for practice sufficient accuracy.

Highlights

Obtaining a quality welded joint involves the determination and finding of the optimal relationship between a large number of parameters, which is very difficult, if not impossible to take into account in real production conditions
All influential quantities that disturb the stability of the process are not considered, whereas only those with the greatest impact are Generally, by taking the Z-side welding process we can think of a set to which sets of input sizes (x) and output sizes (y) are connected, Fig. 1
Mathematical modeling of the butt welding process enables the prediction of optimal welding modes with respect to the dissipation of the value on a particular qualitative requirement at a constant welding mode, and the order of the welding parameters according to the influence on a particular qualitative request

Summary

Introduction

Obtaining a quality welded joint involves the determination and finding of the optimal relationship between a large number of parameters, which is very difficult, if not impossible to take into account in real production conditions. All of these parameters are interdependent and changing; one parameter can cause the value of several other parameters to change, which makes them very complex to study. By taking the Z-side welding process we can think of a set to which sets of input sizes (x) and output sizes (y) are connected, Fig. 1.
