Stripping weld-a new technique of welding enamelled wires by resistance weld

A new technique of directly welding enamelled wires was introduced and the welding theory with relevant experiment results was discussed.By combining SW (stripping welding) tips with capacitor spot welding machine, an equipment to directly weld enamelled wires was designed.Based on setting three proper welding parameters, SW tips realize stripping and welding of enamelled wire in one pulse output by providing ohmic contact on the sharp end of SW tips.Experiments show the merits of the new technique such as the stable welding process, smaller scale nugget and assured welding quality.Now, micro-welding equipment was widely used in industry production, and a new technique of welding the enamelled wire end of small coil of electronic components was provided.
