| Abstract [eng] |
The results of tensile test of ultrasonically welded connections of copper wires are presented in this article. The connections differ by the number o wires in the connection and also by the combination of wires number at the different sides of connection. The dependence of tensile test results on surface preparation of the wires is settled. When the wires are cleaned from the insulation only mechanically small fibers of insulation remain on the surface of the wires. Those fibers reduce connection strength. Additional cleaning of the wires by compressed air before welding increases the strength of connection up to 35 %. The influence of additional cleaning is especially obvious for connections with large number of wires. The analysis of experimental results is done and the dependence of fracture force on the ratio of perimeter / welded connection area is derived. With reference to the results of tensile tests the suggestion for quality development of ultrasonic welding of copper wires is proposed. |
