  • Laser welding method for electrical wire connection to a terminal pin of an exhaust gas sensor
    Patent number: 4230930
    Abstract: A method for welding an electrical lead wire to a terminal pin with the use of a laser beam. The method is particularly designed for use in welding an electrical lead wire of an exhaust gas sensor to a terminal pin having an opening through which the electrical lead wire extends to the exterior of the pin. The lead wire may be made of nichrome material and the terminal pin from leaded steel. The laser beam is positioned vertically above the extended portion of the lead wire and its focal point is above the end of the lead wire. No separate filler metal is required since the lead wire material is itself available as a filler material.
