If the gun type is servo-gun, the playback of spot welding function will be carried out as shown in Figure 2.7.

(1)   From the N-1 step location, the moving tip moves to a location at a distance of moving tip clearance from the record location, and the fixed tip moves to a location at a distance of fixed tip clearance from the record location.

 

(2)   The fixed tip moves to the record location of the step through the robot equalizing operation, and the moving tip moves to the record location of the step by shifting to compensate for consumption.

 

(3)   The moving tip carries out squeeze at the set squeeze force. When the squeeze alignment is achieved, the welding execution signal will be output together with the welding condition signal at that location.

 

(4)   When the welding complete signal (WI) is received, both the moving tip and the fixed tip will be opened sufficiently for clearance.

 

(5)   Continue to the next step.
