Robot Welding

Protech operates a modern fully automatized maintenance line for repair of anode stubs on the anode yoke and rod assemblies. The production line picks up the anode yoke from the storage rack before the maintenance assignment is implemented. The world’s largest ABB robot handles and places the anode hanger on the conveyor line. The anode hanger follows the line until it has been repaired and picked down by the same robot and placed on a stand ready for delivery to the customer.

Safety profile of this system is future-oriented. With adopting Industry 4.0 technology the tasks has changed from phisically demanding to a technology workplace. The customer is quaranteed both the quality and security of supply.
