Abstract
A repair welding device includes an inspection result acquisition unit configured to acquire an appearance inspection result including information about a defective portion of a weld bead of a welded workpiece produced by a main welding that is executed by a welding robot, and a robot control unit configured to instruct the welding robot to execute a repair welding on a position of the defective portion using the appearance inspection result based on a relationship between the position of the defective portion and a predetermined width related to the weld bead.
Claims7
A repair welding device comprising:
- an inspection result acquisition unit configured to acquire an appearance inspection result including information about a defective portion of a weld bead of a welded workpiece produced by a main welding that is executed by a welding robot;
- a robot control unit configured to instruct the welding robot to execute a repair welding on a position of the defective portion using the appearance inspection result based on a relationship between the position of the defective portion and a predetermined width related to the weld bead;
- and
- a repair welding program generation unit configured to generate a repair welding program comprising instructions for:
- executing the repair welding on a corresponding position on a welding line in a same manner as a main welding program, in a case that the defective portion is located at a position where a distance of the defective portion from the welding line is within the predetermined width;
- and
- executing the repair welding by modifying a part of an operational trajectory to the position of the defective portion, thereby directly repairing the defective portion, in a case that the defective portion is farther from the welding line than the predetermined width.
A repair welding method to be executed by a repair welding device, the repair welding method comprising:
- acquiring an appearance inspection result including information about a defective portion of a weld bead of a welded workpiece produced by a main welding that is executed by a welding robot;
- instructing the welding robot to execute a repair welding on a position of the defective portion using the appearance inspection result based on a relationship between the position of the defective portion and a predetermined width related to the weld bead;
- and
- generating a repair welding program comprising instructions for:
- executing the repair welding on a corresponding position on a welding line in a same manner as a main welding program, in a case that the defective portion is located at a position where a distance of the defective portion from the welding line is within the predetermined width;
- and
- executing the repair welding by modifying a part of an operational trajectory to the position of the defective portion, thereby directly repairing the defective portion, in a case that the defective portion is farther from the welding line than the predetermined width.
