Arduino based Battery Tab Resistance Fine-Spot Welder

September 24, 2014 By: admin Category: Arduino, Miscellaneous No Comments →

Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. The process uses two shaped copper alloy electrodes to concentrate welding current into a small “spot” and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt […]
