Aluminium Titanium Copper Trimetallic Explosive Welding Busbar Clads

Explosive welding: The superior option for Clad

The explosive welding creates dissimilar metals into metallurgically bonded. Dissimilar metals are permanently joined for 100% electrical continuity, and demonstrate the characteristics of contiguous metal at the bond interface.

Explosive welding Clad metals 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 bimetallic or trimetallic clads. 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.

Electrical

The electrical resistance of a transition insert is nominally the series resistance of the components. There is no resistance increase or electrical conductivity loss associated with the bond or bonding process.

Temperature

The technology is tensile tested at the bond to exceed the strength of the aluminium. High purity aluminium is typically 85-90MPa in tensile strength, while the RUISEN explosive welding transition joints demonstrates a bond tensile strength of greater than 125MPa.

Strength

Aluminium-copper clad joints can operate safely at elevated temperatures. The parts have been tested to demonstrate tensile strengths greater than 100 MPa after 24 hours at 450°C. All parts have representative bend tests that depict the bond integrity and continuity. The bend testing consists of 3-4 mm slices of the insert cross section bent at 90 degrees at the bond interface. One hundred percent bonding will demonstrate no separations, pinholes, or tears at the interface
