| Abstract: | The paper aims to develop a new method and related device for stable and reliable connection of multi-strand wire and fine wire. Platinum resistance nickel wire lead with a diameter of 0.2 mm and multi-strand copper wire with a diameter of about 0.5 mm were selected for testing. Conventional resistance brazing method and precision resistance brazing method proposed in this paper were respectively used for welding. The welding process experiment was carried out on the precision resistance brazing system to study influences of the process parameters on the welding forming and obtain the optimized process parameters. The tensile force of welded joints obtained by different methods and different technological parameters was tested by precision tensile testing machine to research influence rules of welding methods and process conditions on the shear force of butt joint. The microstructure of the welded joint obtained under different conditions was analyzed and its correlation with the process was studied. The welding joint obtained by conventional welding method has an average tensile strength of 21 N and a strength coefficient of 84%, but there are too many defects and forming errors. The welded joint obtained by precise resistance brazing method has an average tensile strength of 23 N and a strength coefficient of 92%. Both its surface forming and performance meet the requirements. The precision resistance brazing method proposed in this paper is simple to operate and has stable welding quality and high welding efficiency. |
