Abstract

A consumable component for a thermal processing torch is provided. The consumable component includes a consumable component body and a signal device located on or within the consumable component body for transmitting a signal associated with the consumable component. The signal can be independent of a detectable physical characteristic of the consumable component.

Claims

1. A consumable component of a thermal processing torch that includes a receiver disposed inside of the thermal processing torch, the consumable component comprising:

a consumable component body; and

a signal device, comprising a radio-frequency identification (RFID) tag, located on or within the consumable component body for transmitting a signal associated with the consumable component, the signal being independent of a detectable physical characteristic of the consumable component,

the signal device being configured to store information to be conveyed by the signal identifying two or more of the consumable'"'"'s name, trademark, manufacturer, serial number, usage history, at least one operating parameter, and type, and

the signal device being located inside of the thermal processing torch when the consumable component is installed in the thermal processing torch and the signal device being configured to allow the signal to be readable by the receiver inside the thermal processing torch.

2. The consumable component of claim 1 wherein the signal transmitted by the signal device identifies at least one feature unique to the type of the consumable component.

3. The consumable component of claim 2, wherein the type of the consumable component comprises a nozzle, a shield, an electrode, an inner retaining cap, an outer retaining cap, a swirl ring or a welding tip.

4. The consumable component of claim 1, wherein the signal transmitted by the signal device identifies at least one feature unique to the consumable component that is capable of distinguishing the consumable component from another consumable component of the same type.

5. The consumable component of claim 1 wherein the signal device is located at a surface of the body to minimize heat exposure during torch operation.

6. The consumable component of claim 5 wherein the surface is adjacent to a cooling mechanism of the thermal processing torch, spaced away from a plasma arc emitted from the thermal processing torch, or in an o-ring channel of the thermal processing torch, or a combination thereof.

7. The consumable component of claim 5 wherein the signal device is shielded by another torch component to minimize exposure of the signal device to at least one of thermal energy, radiation, damaging gases, or high-frequency energy.

8. The consumable component of claim 1 wherein the signal device is adapted to transmit the signal before, during or after plasma arc ignition, or a combination thereof.

9. The consumable component of claim 1 wherein the thermal processing torch comprises a plasma arc torch.

10. A system for conveying information about a thermal processing torch, the system comprising:

a signal detector;

at least one consumable selected from a group comprising;

an electrode, a nozzle, a shield, a retaining cap, a welding tip, and a swirl ring;

at least one signal device, comprising a radio-frequency identification (RFID) tag, attached to the at least one consumable for conveying information about the at least one consumable to the signal detector,

the at least one signal device being configured to store the information identifying at least one operating parameter of the torch and a value for the at least one operating parameter, and

the signal device being located inside of the thermal processing torch when the consumable component is installed in the thermal processing torch and the signal device being configured to allow the information to be readable by the signal detector inside the thermal processing torch; and

a controller coupled to the signal detector for i) receiving the information from the at least one signal device, and ii) transmitting at least a portion of the information to at least one of a processor, a gas console, nesting software, a height controller, and a drive motor, wherein at least one of the processor, the gas console, the nesting software, the height controller, and the drive motor adjusts torch operation based on the value of the at least one operating parameter.
