Abstract

Information pertaining to characteristics of metal welding electrode wire and which characteristics are useful in connection with adjusting welding parameters in an arc welding process and/or selecting between operating modes in a welding system are encoded on welding wire and/or on other memory components such as bar code labels and tags, RFID cards and tags, IC cards, and Touch Memory buttons, and the memory device is scanned prior to and/or at the point of use of the welding wire for enabling tracking of product distribution, manual and/or automatic selection of an operating mode for the welding system, manual and/or automatic adjustment of welding parameters in a given operating mode, consumables inventory, and the like.

Claims

1. A method of maintaining an inventory of consumables in conjunction with performing an electric arc welding process wherein a welding wire is advanced toward a workpiece, a welding arc is established between the advancing wire and the workpiece;

and the arc is shielded by a protective gas, including the steps of;

a) providing a container of protective gas to be used in the welding process with an electronic device having a memory for storing information pertaining to the available quantity of welding wire in the container;

b) measuring the quantity of wire consumption during the performance of the welding process; and

,

c) electronically modifying the memory of the electronic device for the available quantity of wire to reflect said wire consumption.

2. The method according to claim 1, including the further steps of:

d) retrieving the stored information; and

,

e) at least one of displaying and printing the retrieved information.

3. The method according to claim 1, wherein said electronic device is one of a RFID component, an IC component, and a semi-conductor memory chip.

4. The method according to claim 1, wherein said electronic device is a first electronic device, and including the further steps of:

d) providing a container of protective gas to be used in the welding process with a second electronic device having a memory for storing information pertaining to the available quantity of gas in the container;

e) measuring the quantity of gas consumption during the performance of the welding process; and

,

f) electronically modifying the memory of the second electronic device for the available quantity of gas to reflect said gas consumption.

5. The method according to claim 4, including the further steps of:

g) retrieving the stored information from said second electronic device; and

,

h) at least one of displaying and printing the information retrieved from said second electronic device.

6. The method according to claim 4, wherein the second electronic device is one of a RFID component, an IC component, and a semi-conductor memory chip.

7. A method of maintaining an inventory of consumables in conjunction with performing an electric arc welding process wherein a welding wire is advanced toward a workpiece, and a welding arc is established between the advancing wire and the workpiece including the steps of:

b) measuring the quantity of wire consumption during the performance of the welding process; and

,

c) electronically modifying the memory of the electronic device for the available quantity of wire to reflect said wire consumption.

8. A method of maintaining an inventory of consumables in conjunction with performing an electric arc welding process wherein a welding wire is advanced toward a workpiece, and a welding arc is established between the advancing wire and the workpiece including the steps of:

a) providing a container of protective gas to be used in the welding process with an electronic device having a memory for storing information pertaining to the available quantity of gas in the container;

b) measuring the quantity of gas consumption during the performance of the welding process; and

,

c) electronically modifying the memory of the said electronic device for the available quantity of gas to reflect said gas consumption.

9. The method according to claim 8, including the further steps of:

d) retrieving the stored information from said second electronic device; and

,

e) at least one of displaying and printing the information retrieved from said electronic device.

10. The method according to claim 8, wherein said electronic device is one of a RFID component, an IC component, and a semi-conductor memory chip.
