Battery Assembly

Our Welders are Uniquely Positioned to Meet Increased Demand for High Power Electric Vehicle Batteries and Charging Stations

Sonobond’s metal welders can add eco-friendly, dependable, cost-effective performance to your manufacturing operation.

Using our patented Wedge-Reed System – with no external heat, current or fillers – our units create solid-state, highly conductive welds, eliminating metallurgical defects such as porosity and intermetallics that commonly exist in fusion welds.

This System also welds tinned and oxidized metals – a unique ability unmatched by any other ultrasonic system.

Dual head welders for battery assemblyDual-Head Systems for Advanced Storage Capacity Batteries

Our welders quickly and reliably weld multiple anode and cathode foils to battery tabs and terminals, as well as stranded copper wires to terminals. Our dual-head welding and splicing systems accommodate the larger wire bundles and terminals required for rechargeable batteries that must have high power and high storage capacities.

Sonobond’s Dual Head Spot Welder is the first ultrasonic model to join up to 100 layers of copper or aluminum foil in just one pulse without tearing the foils – even if they’re as thin as seven microns. And our Dual Head Wire Splicer welds stranded copper wire bundles up to 100 sq.mm cross sectional area.
