ABSTRACT:
A method and apparatus for sensing the temperature of a susceptor in a bond line in an inductive welding process utilizing a conductive susceptor at the interface between the two plastic parts, and a magnetic coil that generates an alternating magnetic field and projects the field through the parts and around the susceptor. As the susceptor gets hot, its electrical resistance changes as a function of the thermal coefficient of resistance of the susceptor material, and that change of resistance is reflected back as a change in the drive coil impedance. An electrical circuit senses the varying resistance and that change in resistance is translated into a change of temperature on a temperature display, and may be used to adjust the power to the work coil or the speed of travel of the work coil along the bond line. The circuit includes a high power bridge with a sensitive null arm to sense changes in the susceptor impedance due to temperature changes.
