Abstract
The paper studies the interface relief of copper–tantalum, copper–titanium and copper–copper joints. It demonstrates that interfaces could be considered as a fractal object. Fractal dimensions are calculated for these joints. A rule is established for the behavior of the fractal dimension during the transition from flat interfaces to wavy ones; this rule holds true of all joint pairs. Some behavior specifics are found for the fractal dimension of wavy interfaces of the copper–copper joint (which was substituted with Cu-Cu80Ni20 joint for convenience). The study shows that the fractal dimension in general decreases when welding modes are intensified. However, in the case of welding modes that are close in terms of energy input, certain peculiarities or deviations from such behavior can be observed. Graphical AbstractKeywords
