Potroom Clads

Overview

Clads are a low-resistance, high-strength joint that allows the welding of two dissimilar metals.  They are for use in high-current, high-temperature, and mechanical stress environments.

In the potroom, steel anode yokes are pre-welded to the aluminium anode rods using a trimetallic clad. This anode clad is a preformed aluminium/steel joint allowing the welding of the aluminium rod to the steel yoke, and forms a low-resistance, high-strength joint to withstand the elevated temperatures, mechanical abuse, and high current density found in the process. Cathode/collector bars are connected to aluminum flexibles of the busbar system through welded or bolted aluminum/steel or aluminum copper cathode clads. The anode ring busbar is connected to the aluminium anode stem via aluminium/copper clads.

Pyrotek Offerings

Pyrotek offers anode clads, cathode clads, anode beam clads, and zinc clads. All are available with varying levels of aluminium/steel or aluminum/copper grade options and in various sizes to meet dimensional requirements.

Pyrotek clads are formed with a high integrity metallurgical joint, which extends the service temperature and transition insert life while maintaining high electrical and thermal conductivity.
