摘要：
A method and apparatus for manufacturing a lamp involves preparing a lamp assembly having a base to which is coupled a bulb with external lead-in wires. One of the lead-in wires has an outer end which is drawn out between the bulb and the edge of the base. A potential is applied between a welding electrode of a welding device and the tip of the outer end of the external lead-in wire to weld the lead-in wire to the base. During this applying of potential, a gas flame is interposed between the outer end of the external lead-in wire and the welding electrode.
