Welding techniques for battery cells and resulting electrical contact resistance…

Hence, resistance spot welding, ultrasonic welding and laser beam welding are mostly applied. Using the example of two battery cells connected in parallel, Fig. 1 illustrates the influence of the quality of cell connections on a battery assembly. The higher electrical contact resistance RC,1 generates more heat at the terminal of cell 1.

Resistance Welding Fundamentals

GENERAL PRINCIPLES. Resistance welding is a thermo-electric process in which heat is generated at the interface of the parts to be joined by passing an electrical current through the parts for a precisely controlled time and under a controlled pressure (also called force). The name "resistance" welding derives from the fact that the ...

What is Resistance Welding?

Resistance welding is generally used to join two plain metal work pieces together. An electric current is delivered to the metal sheets (or any work pieces being joined) through weld electrodes which apply force to the sheets. This force is then converted to heat. The heat is generated so that it melts the metal at the point where they join ...
