Micro Welding
Micro welding encompasses precision resistance welding techniques for joining miniature components, fine wires, and delicate assemblies. With precise control over current, time, and force at the micro-scale, this technology enables reliable connections in electronics, medical devices, and advanced manufacturing applications.
How Micro Welding Works
Micro welding applies the principles of resistance welding at a miniature scale. Precision power supplies deliver carefully controlled current pulses measured in milliseconds or microseconds, while miniature electrodes apply precisely calibrated force to create strong, reliable joints without damaging sensitive components.
The process can be configured for spot welding, parallel gap welding, or series welding depending on the application. Advanced controls monitor and adjust parameters in real-time to ensure consistent weld quality.
