Welding technology of fuse element

Abstract

The invention discloses a welding technology of a fuse element. According to the welding technology, a spot welding machine and an element to be welded are prepared, and the element to be welded is arranged between an upper electrode and a lower electrode of the spot welding machine and is connected with a circuit through a welding head. The element to be welded comprises a fuse element and a conductive touch plate, and the fuse element is arranged on the conductive touch plate. The fuse element is made of sheet-shaped or filamentous metal materials. The conductive touch plate is made of copper or copper alloy materials. The welding head is made of hard alloy materials. The spot welding machine can adjust the output voltage to achieve welding of different materials and materials of different thicknesses. The spot welding positions in the welding process are on the inner side of the conductive touch plate. The welding technology solves the problem that cold joints are prone to being generated in the traditional welding technology, the production efficiency is high, the output power is controllable, welding demands of precise parts of different thicknesses and different materials can be met, and produced fuses are good in consistency, stable in performance, high in breaking speed and attractive in appearance.
