The HF-WX-20DA by Haifei is a professional-grade 20kHz ultrasonic spot welder engineered specifically for the demanding requirements of the New Energy Vehicle (NEV)and Energy Storage (ESS) sectors.
Unlike traditional resistance welding, our ultrasonic technology creates a solid-state molecular bond between non-ferrous metals like copper, aluminum, and nickel. This ensures zero melting, minimal electrical resistance, and unmatched joint strength for critical battery assembly.
