The pillar of USIBOR is made in 4 steps, 3 of them require a jig. The jigs are mounted on a 2-station-rotating table. The welding process employs 3 robots: 2 robots hold a welding clamp and execute the welding points with the pillar on the jig. The third robot has a gripper and finishes the welding with the free standing part by means of a welding machine on the floor. The unload is automatic: the third robot deploys the finished part on the conveyor. The load is made by an operator.
