## Abstract

On the basis of location information which signifies a clamp location of a jig with respect to a new workpiece, new workpiece cross-section information is recognized in the clamp location. Next, a search is carried out among existing workpiece cross-section information for information similar to the recognized new workpiece cross-section information. Next, jig information is selected which is linked to the found workpiece cross-section information. Next, the selected jig information and the location information are linked and set to new workpiece design information.

## Claims

### Claim 1

A jig information setting method of setting jig information of a jig for supporting a new workpiece, with respect to design information of the new workpiece for a welding operation, the method performed by a processor, comprising:
a cross-section information recognition step of recognizing new workpiece cross-section information at a clamping position of the jig, based on positional information indicative of the clamping position; and
a jig information setting step of retrieving information similar to the new workpiece cross-section information from existing workpiece cross-section information, selecting the jig information associated with the existing workpiece cross-section information retrieved, and setting the selected jig information and the positional information in association with each other to the design information,
wherein the new workpiece cross-section information contains information about coordinates of a center of gravity of a cross section of the new workpiece, information about a normal vector of the cross section of the new workpiece, and information about a shape of the cross section of the new workpiece,
wherein the existing workpiece cross-section information contains information about coordinates of a center of gravity of a cross section of the existing workpiece, information about a normal vector of the cross section of the existing workpiece, and information about a shape of the cross section of the existing workpiece, and
wherein the clamping position is one of a plurality of clamping positions 1-n and wherein the processor is configured to perform the cross-section information recognition and the information setting steps sequentially for each of the clamping positions 1-n.

### Claim 2 (depends on 1)

The jig information setting method according to claim 1, further comprising a step performed by the processor a positional information setting step of determining the clamping position of the jig, and setting the positional information indicative of the clamping position to the design information, prior to the cross-section information recognition step.

### Claim 3
