Abstract

Provided is a welding program production system that can increase efficiency of a welding operation by a welding robot. The welding program production system includes a display control unit that causes a plurality of candidate welding lines detected on the basis of an image of a photographed object to be welded to be displayed in superimposed relation on the image, an input receiving unit that receives an input to select the welding lines from among the plurality of candidate welding lines and an input to specify a welding order and a welding direction for each of the selected welding lines, and a program production unit that produces a welding program on the basis of the specified welding order and welding direction.

First claim

What is claimed is:

1 . A welding program production system comprising:
a display control unit that causes a plurality of candidate welding lines detected on the basis of an image of a photographed object to be welded to be displayed in superimposed relation on the image; an input receiving unit that receives an input to select the welding lines from among the plurality of candidate welding lines and an input to specify a welding order and a welding direction for each of the selected welding lines; and a program production unit that produces a welding program on the basis of the specified welding order and welding direction.

2 . The welding program production system according to claim 1 , further comprising:
a determination unit that determines a range weldable by the welding robot on the basis of a position at which the welding robot is to be disposed, wherein the display control unit causes the candidate welding lines which are among the plurality of candidate welding lines and present within the weldable range determined by the determination unit to be displayed in superimposed relation on the image.

3 . The welding program production system according to claim 1 , wherein the input receiving unit receives, as the input to specify the welding direction, an input to specify a welding starting position and a welding ending position.

4 . The welding program production system according to claim 1 , wherein the input receiving unit receives, as the input to specify the welding direction, an input to trace each of the welding lines.

5 . The welding program production system according to claim 1 , further comprising:
a welding line detection unit that calculates, on the basis of the image, coordinate data corresponding to the object to be welded and detects, on the basis of the coordinate data, the plurality of candidate welding lines.

6 . A welding program production method which is a method to be implemented by a processor, the method comprising the steps of:
causing a plurality of candidate welding lines detected on the basis of an image of a photographed object to be welded to be displayed in superimposed relation on the image; receiving an input to select the welding lines from among the plurality of candidate welding lines and an input to specify a welding order and a welding direction for each of the selected welding lines; and producing a welding program on the basis of the specified welding order and welding direction.
