Abstract:
A spray quench system is provided with one or more spray quench rings that eject a controlled volume of spray onto a workpiece passing through the quench rings. The quench rings can be adjusted in position independently of each other relative to the workpiece being sprayed. Reflected spray guards may be provided to prevent spray interference between adjacent quench rings. The outlets of the quench rings may be adjustable in volume. A controller can be provided to optimize the distribution of quench cooling flows from the quench rings. Sets of quench rings with different diameters in each set may be provided in modular form.
Abstract:
Method and system for monitoring and controlling at least one of the plurality of quantifiable heat affected zone ("HAZ") characteristics in a weld of metal pieces provides a user with information concerning at least a first quantifiable HAZ characteristic for a weld, and also provides for control of an operating condition of a welding apparatus to obtain a weld having a quantifiable HAZ characteristic that satisfies success criteria relating to performance of the fabricated component.
Abstract:
High frequency electrical heating apparatus in which metal parts (10) are heated as they are advanced, either for annealing or forge welding purposes, and in which the electrical heating current is supplied by a solid state D.C. to A.C. inverter (2-5, 8) through a load matching and frequency control circuit (13) which maintains the desired load current and current frequency with changes in the load impedance caused by the metal parts (10) as they are advanced.
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:
A series of time sequenced heat energy data arrays or data stream sets of a weld process region are processed by a weld data array or data stream processing system to produce a heat energy data set output that is related to weld process region features or weld process region heat energy data. The heat energy data set output can be displayed to a system user and modified by system user input to the weld data array or data stream processing system; alternatively, or in combination, the system user output and input, the heat energy data set output, or data produced from the heat energy data set output by the weld data array or data stream processing system, can be transmitted to a weld process controller to adjust parameters in the weld process responsive to the output of the weld data array or data stream processing system.
Abstract:
A spray quench system is provided with one or more spray quench rings that eject a controlled volume of quenchant spray onto a workpiece passing through the quench rings. Supply of the quenchant to the quench rings is coordinated with control of the quench rings to selectively change the pressure, quenchant spray exit velocity from the quench rings, flow rate or pattern of the quenchant spray onto the workpiece depending upon mass cooling requirements as the workpiece passes through the quench rings.
