    Abstract: PROBLEM TO BE SOLVED: To provide a method and system for monitoring and controlling at least one of the plurality of quantifiable heat affected zones (HAZ) characteristics in a weld of metal pieces.
    SOLUTION: The method for monitoring and controlling at least one of the plurality of quantifiable HAZ characteristics in a weld of metal pieces comprises a step of determining a predictive HAZ characteristic value on the basis of the condition of welding process factors for weld, wherein the welding process factors include sizes, shapes and qualities of the metal pieces and the operating condition of a welding apparatus, a step of determining the optimum HAZ characteristic value for a weld to be conducted on metal pieces, and a step including at least one of the steps (a) and (b), wherein the step (a) indicates the quantity relating to the predictive HAZ characteristic value and to the optimum HAZ characteristic value and the step (b) controls a control component for controlling at least one of the operating conditions of the welding apparatus and corrects the predictive HAZ characteristic value in relation to the optimum HAZ characteristic value.

    Abstract: A solenoidal induction coil with dynamically variable coil geometry is provided for inductively welding or heating continuous or discontinuous workpieces passing through the solenoidal induction coil in a process line. The coil geometry can change, for example, as the outer dimension of the workpiece passing through the solenoidal induction coil changes or as non-continuous workpieces pass through the solenoidal induction coil in an induction heating or welding process line.

    Abstract: A method and apparatus in which edge portions of metal parts (1), the edge portions being disposed with opposed surfaces (3, 4), are heated by high frequency electrical currents as the edge portions are advanced and brought together at a weld point (5). The electrical currents are induced in the edge portions in advance of the weld point (5) by two induction coils (6, 7), one at one side of the metal parts (1) and the other at the other side of the metal parts (1), disposed and energized from a high frequency electrical source so that the electrical currents at the opposed surfaces flow in opposite directions at any given time and the currents induced by one coil (6) add to the currents induced by the other coil (7).

    Abstract: High frequency electrical heating system is provided for heating electrically conductive parts as they are advanced, either for annealing or welding processes, and in which the electrical heating current is supplied by a solid state DC to AC inverter through a load matching and frequency control circuit that maintains the desired load current and frequency with changes in the load impedance caused by the electrically conductive parts as they are advanced. Load matching is achieved with high frequency variable reactors having a geometrically-shaped moveable insert core section and a stationary split-bus section with a complementary geometrically-shaped split bus section and a split electric terminal bus section where the insert core section can be moved relative to the stationary split-bus section to vary the inductance of the reactor pair.
