Hanging galvanized automatic line In the manufacturing process of electric detonator's electric igniter, welding nickel chromium alloy wire on the metal wire is an important process. When the metal leg wire is galvanized iron leg wire, the energy storage automatic welding machine is mostly used for this welding work at present. The working voltage of the energy storage capacitor of the welding machine is 180V ± 5V, and the welding torque is cylindrical copper bar. The welding process is generally divided into two steps: first, the capacitor emits high current, which generates a lot of heat on the welding head and fuses the nickel chromium alloy wire; Second, the welding head flattens the galvanized iron wire, and at the same time, the welding head generates a lot of heat to fuse the galvanized iron wire with the nickel chromium alloy. The welding torque used as the electrode rod is copper and cylindrical in shape. The welding torque is clamped on the holder of the welding head of the welder· When the metal lead is copper lead, the energy storage automatic welding machine cannot be used to weld the "copper lead nickel chromium alloy wire" due to the low melting point of copper, soft material and other reasons, and only manual welding can be used. In this way, not only the efficiency of welding operation is low, but also the quality of welding products cannot be guaranteed, and the rework and repair rate and defect rate are high.
