  • Patent number: 4426565
    Abstract: A method and apparatus for controlling the travel speed of automatic welding machines uses a rotatable member which is engaged with the workpiece as the workpiece is moved relative to the welding head. The rotatable member advantageously includes one or more apertures on one side of which light is directed and the opposite side of which light pulses are received during rotation of the member and these pulses are used as an indication of the speed of the welding machine. In the preferred apparatus a separate frictional member is frictionally engaged with the workpiece and moved by the movement of the workpiece relative to the welding head and through suitable gearing drives the rotatable member having the aperture.
