A spot welding machine, specially used for the welding of electronic detonator delay element with leg wire and rigid flash component, was developed to meet the needs of the production of electronic detonator in domestic market. It is mainly composed of dicephalous resistance welder, step feeding mechanism of fuse head, manipulator deliver mechanism, forming step mechanism of delay element, electronic control system, cooling systems and so on. The main problems were solved in terms of the selection of welding parameters; the choice of welding machine and welding structure design; the rows facing of rigid fuse head and delay element; design of step feeding mechanism of fuse head, manipulator deliver mechanism, forming step mechanism of delay element and cooling system. The welding quality conforms to the needs of electronic detonator production, and its welding efficiency is 400 rounds/ hour.
