Title:
AUTOMATIC WELDING METHOD AND CONTROLLING DEVICE FOR AUTOMATIC WELDING ROBOT
Document Type and Number:
Japanese Patent JP3913614
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide an automatic welding method and a controlling device for an automatic welding robot capable of evenly finishing a welding bead shape even if a grooved shape of the welding joint fluctuates.
SOLUTION: When the grooved shape of the set weld joint 6 fluctuates by comparing with the grooved shape of the weld joint initially set as a model in the confirmable teaching process of the welding robot 1, the distance L to the weld conditions change position which is located before the next teaching position P3 of the teaching position P2 from the teaching position P2, and the weld conditions to be changed are set and entered through the operator's confirmation. Based on the distance L set and entered, the weld conditions change position is calculated through interpolation. In the regenerative operation process of the welding robot 1, welding is performed by shifting to the weld conditions set and entered at the calculated weld conditions change position.
