Sonobond Ultrasonics has introduced two ultrasonic metal welding machines.
The Dual Head SpliceRite™ can weld wire bundles with cross-sectional areas of up to 3.94 sq. in. According to the manufacturer, no other ultrasonic welder can equal this capacity in a single pulse. This makes the machine suitable for applications involving heavy-duty cables used in cars, trucks, and industrial machinery.
With appropriate tooling, the Dual Head Spot Welder can weld nonferrous sheet metal. In addition, it can weld up to 80 layers of foils, making it suitable for advanced battery and supercapacitor applications.
Both machines use the company's 3,500-W power supply and can accommodate lightly tinned or oxidized wires. The microprocessor controller—which is standard for both units—can weld by height or time. It also can recall up to 250 weld protocols.
All of the manufacturer's ultrasonic spot welders use the patented Wedge-Reed bonding system, which combines high vibratory force with low-amplitude coupling to help produce precise welds. It uses shear mode vibration that is parallel to the welding surface and eliminates bending stress by positioning the line of force directly over the welding surface.
