  • Weld tracking/electronic arc sensing system
    Patent number: 4336440
    Abstract: Apparatus for tracking a welding electrode (22) within a weld groove (12). As the welding arc struck between the electrode (22) and the workpiece (16) is oscillated laterally (14) within the groove means (28 and 30) are provided for supplying an indication of both the voltage drop between the electrode and the side wall of the groove as the arc approaches the side wall, and the width of the excursion of the arc from the center of oscillation to the point where the voltage is measured. The center of oscillation is then adjusted as a function of the measured width and voltage.
