Abstract

Radio-tagged components are used a welding operation to form a welded product. Pedigree/quality control is monitored by tagging welding wire with a first radio transceiver storing information about the wire; providing a second radio transceiver at the welding apparatus, providing a third radio transceiver associated with the at the human operator, logging information about the wire, the operator, and the characteristics of the weld, and maintaining the logged information at a location remote from the welder along with a time stamp and a means of authenticating the maintained log. The first, second and third transceivers operate at a frequency below 1 megahertz, preferably below 300 KHz. A similar radio tag with product pedigree information may also be affixed to the welded product.

Claims

1. A method for use in welding with a human operator and a welding apparatus to form a welded product, said method comprising the steps of:

(a) tagging welding wire with a first radio transceiver storing information about the wire;

(b) providing a second radio transceiver at the welding apparatus,

(c) providing a third radio transceiver associated with the at the human operator,

(d) logging the information about the wire, the operator, and the characteristics of the weld, and

(e) maintaining the logged information at a location remote from the welder along with a time stamp and a means of authenticating the maintained log,

wherein the first, second and third transceivers operate at a frequency below 1 megahertz.

2. The method of claim 1, wherein the first, second and third transceivers operate at a frequency below 300 KHz.

3. The method of claim 1, wherein the first, second and third transceivers operate at a frequency of 133 KHz.

4. The method of claim 1, further comprising the step of providing a fourth radio transceiver on the welded product, said fourth radio transceiver have stored information concerning the pedigree of the welded product, wherein the fourth transceiver operates at a frequency below 1 megahertz.

5. The method of claim 4, wherein the first, second, third and fourth transceivers operate at a frequency below 300 KHz.

6. The method of claim 4, wherein the first, second, third and fourth transceivers operate at a frequency of 133 KHz.

7. Welding wire having associated therewith a radio transceiver that operates at a frequency below 1 megahertz, said transceiver storing information concerning the type and provenance of the welding wire.

8. Welding wire according to claim 7, wherein the transceiver operates at a frequency below 300 KHz.

9. Welding wire according to claim 7, wherein the transceiver operates at a frequency of 133 KHz.

10. Welding equipment having associated therewith a radio transceiver that operates at a frequency below 1 megahertz, said transceiver storing information concerning the identification of the equipment.

11. Welding equipment according to claim 10, wherein the transceiver operates at a frequency below 300 KHz.

12. Welding equipment according to claim 10, wherein the transceiver operates at a frequency of 133 KHz.

13. Welding equipment according to claim 10, wherein the welding equipment is a wire feeder.

14. Welding equipment according to claim 13, wherein the transceiver has the ability to read information for a second transceiver associated with welding wire.

15. Welding equipment according to claim 14, wherein the transceiver operates at a frequency below 300 KHz.

16. Welding equipment according to claim 14, wherein the transceiver operates at a frequency of 133 KHz.

17. Welding equipment according to claim 10, wherein equipment is a welder.

18. A welded product comprising at least two metal components joined together by a weld and a radio transceiver that operates at a frequency below 1 megahertz affixed to one of the components, said transceiver storing information concerning the formation of the weld.

19. The welded product according to claim 18, wherein the transceiver operates at a frequency below 300 KHz.

20. The welded product according to claim 18, wherein the transceiver operates at a frequency of 133 KHz.

21. The welded product according to claim 18, wherein the information concerning the formation of the weld includes one or more of the identity of the welding wire used, the specific welding apparatus used, the human operator of the welding apparatus, and the date the weld was formed.

22. The welded product according to claim 21, wherein the transceiver operates at a frequency below 300 KHz.

23. The welded product according to claim 21, wherein the transceiver operates at a frequency of 133KHz.
