Ultrasonic Spot Welder XN-UMW-2000

Product Introduction

The RSC-UMW-2000 Ultrasonic Spot Welder is designed for metal welding applications in battery tab welding, foil welding, and thin metal joining processes. Featuring a compact structure, user-friendly operation, and stable performance, it provides reliable ultrasonic welding without the need for flux, additives, or pre-treatment. The system is well-suited for laboratory research, pilot production, and precision manufacturing.

Product Features

Touch-screen interface for intuitive operation, with automatic frequency tracking
Flux-free welding process; ultrasonic vibration removes surface contamination and oxide layers naturally
No pre-treatment required; welding can be completed without solder or chemical additives
High welding efficiency with short welding cycle time (typically 0.1–2.5 seconds per weld)
Low heat input; welding temperature remains well below the metal melting point, preserving material properties
Excellent electrical conductivity after welding with low contact resistance
Strong and consistent weld strength with good repeatability
Low noise, low vibration, easy operation, and minimal maintenance
Safe operation without smoke, sparks, or harmful emissions
