WELDING SYSTEM, WELDING METHOD, WELDING ROBOT, AND PROGRAM

WIPO Patent Application WO/2022/224714

A1

This welding system comprises: a welding robot having a movable part that moves integrally with a welding torch; a control device for controlling movement of the welding robot; and a temperature sensor that is attached to the movable part, and measures, in a contactless manner, an interpass temperature of an object to be welded, which is present on a measurement axis. The central axis of the welding torch and the measurement axis of the temperature sensor are in a relationship in which the central axis of the welding torch and the measurement axis of the temperature sensor three-dimensionally intersect in a space, and a point at which the central axis of the welding torch and the measurement axis of the temperature sensor three-dimensionally intersect is ahead of a tip of the welding torch on the central axis of the welding torch. Moreover, the control device controls movement of the welding torch so as to locate the measurement axis of the temperature sensor at a temperature measurement position calculated in advance.
