Abstract

A welding-type system is designed for wireless control and for inventory monitoring of welding consumables. The welding-type system includes a power source to produce a welding-type power, wherein the power source is operable in a plurality of operating modes. The welding-type system also includes a controller configured to set a plurality of operating parameters within the power source, at least one wireless monitoring device coupled to the controller, and at least one welding-type consumable associated with a wireless transmitter. The wireless transmitter is configured to emit low frequency magnetic signals having consumable data encoded therein that is indicative of the at least one welding-type consumable. The wireless monitoring device is arranged to communicate with the wireless transmitter by receiving and transmitting the low frequency magnetic signals, with the low frequency magnetic signals being transmitted at a frequency of approximately 131 kHz.

Claims

1. A system comprising:

a power source for producing welding-type power;

a controller configured to set a plurality of operating parameters of the power source;

a welding-type consumable container holding a welding-type consumable, the welding-type consumable container having a first wireless transmitter supported thereon, the first wireless transmitter having a dedicated power supply and being configured to transmit consumable data, wherein the consumable data is data indicative of the welding-type consumable;

a second wireless transmitter supported by a welding workpiece, wherein the second wireless transmitter is configured to transmit welding workpiece data; and

a wireless monitoring device coupled to the controller and configured to receive the consumable data and the welding workpiece data.

2. The system of claim 1, wherein the wireless monitoring device is configured to communicate with the controller and transmit the consumable data thereto.

3. The system of claim 2, wherein the controller is configured to set the plurality of operating parameters of the power source based on the consumable data transmitted thereto by the wireless monitoring device.

4. The system of claim 2, wherein the controller is configured to select one of a plurality of operating modes for operating the power source based on the consumable data transmitted thereto by the wireless monitoring device.

5. The system of claim 1, wherein the plurality of operating parameters comprises a current wave shape, a welding wire feed speed, a welding angle, an arc current, an arc voltage, a current polarity, power, arc length, or a shielding gas flow rate.

6. The system of claim 1, wherein the first wireless transmitter comprises a wireless tag including:

a tag antenna;

a transceiver operatively connected to the tag antenna and configured to emit and receive magnetic signals;

a data storage device operable to store the consumable data thereon and identification data to identify the wireless transmitter;

a programmed data processor configured to process data received from the transceiver and the data storage device, and to send data to cause the transceiver to emit an identification signal based upon the identification data stored or a consumable signal based upon the consumable data stored; and

an energy source for activating the transceiver and the programmed data processor.

7. The system of claim 6, wherein the consumable data comprises a type and an amount of the welding-type consumable.

8. The system of claim 7, comprising a consumable amount sensor configured to measure a quantity of consumption of the welding-type consumable during performance of a welding operation and relay a signal to the wireless tag to modify the consumable data on the data storage device to reflect a remaining quantity of the welding-type consumable.

9. The system of claim 1, wherein the wireless monitoring device comprises:

a field antenna configured to receive the magnetic signals emitted by the wireless transmitter;

a reader in communication with the field antenna to receive the consumable data encoded in the magnetic signals; and

a transmitter in communication with the field antenna, the transmitter configured to send data signals to the wireless transmitter.

10. The system of claim 1, wherein the first wireless transmitter is configured to transmit the consumable data using a bidirectional, on-demand, peer-to-peer, radiating transceiver tag protocol.

11. A wireless communication system, comprising:

a power source for producing welding-type power;

a controller configured to set a plurality of operating parameters of the power source;

a wireless monitoring device coupled to the controller;

a first wireless transceiver tag in communication with the wireless monitoring device, the first wireless transceiver tag having a dedicated power supply and being supported by a container holding a welding-type consumable, wherein the first wireless transceiver tag is configured to communicate consumable data to the wireless monitoring device, wherein the consumable data is data indicative of the welding-type consumable; and

a second wireless transceiver tag supported by a welding workpiece, wherein the second wireless transceiver tag is configured to communicate with the wireless monitoring device via magnetic waves having welding workpiece data encoded therein.

12. The wireless communication system of claim 11, wherein the controller is configured to set one or more of the plurality of operating parameters of the power source based on the consumable data.

13. The wireless communication system of claim 11, wherein the first wireless transceiver tag comprises a data storage device configured to store the consumable data, the consumable data comprising an amount of the welding-type consumable.

14. The wireless communication system of claim 13, wherein the data storage device comprises a writeable memory configured to store an updated amount of the welding-type consumable based on a measured consumption of the welding-type consumable.

15. The wireless communication system of claim 13, wherein the consumable data comprises a type of the welding-type consumable.

16. The wireless communication system of claim 11, wherein the welding workpiece data includes data that specifies one or more of a desired welding wire feed speed, a desired welding angle, a desired arc current, a desired arc voltage, a desired current polarity, a desired power, a desired arc length, and a desired shielding gas flow rate.

17. The wireless communication system of claim 16, wherein the controller is configured to determine whether proper welding-type consumables are available for performing a welding process corresponding to the welding workpiece data, and wherein the determination is based at least in part on the consumable data.

18. The wireless communication system of claim 17, wherein the controller is configured to disable the power source or trigger an alert in response to a determination that proper welding-type consumables are not available for performing the welding process corresponding to the welding workpiece data.
