Beschreibung
Zusammenfassung:	A welding system includes: a welding robot having a movable portion that can move integrally with a welding torch; a control device that controls movement of the welding robot; and a temperature sensor that is attached to the movable portion and measures an interpass temperature of an object to be welded present on a measurement axis in a noncontact manner. A central axis of the welding torch and the measurement axis of the temperature sensor are in a relation of three-dimensionally intersecting in a space, and a position where the central axis and the measurement axis three-dimensionally intersect is ahead of a tip end of the welding torch on the central axis of the welding torch. The control device controls movement of the welding torch such that the measurement axis is positioned at a measurement position of the temperature calculated in advance.
