Resistance welding is a method of welding by applying pressure to the weldment through electrodes and by using resistance heat generated by current passing through the contact points, also called contact welding. During welding, the workpieces are pressed between two electrodes, and a current is applied for a certain time.
The power supply for resistance welding machine could be alternating current, direct current, or pulse current. Alternating current frequency is divided into four types: low frequency (3–10 Hz), power frequency (50/60 Hz), medium frequency (150–8000 Hz), and high frequency (10–500 kHz).
The advantages of resistance welding are the formation of plastic connection or molten core surrounded by plastic ring connection. It has simple metallurgical process, short heating time, heat concentration, small heat-affected zone, small stress and deformation, and high welding quality.
Resistance spot, ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies. Each of these welding techniques has its own characteristics depending on the material properties and contact geometry. Cell casing and terminal dimensions may constrain possible contact geometries.
As explained above, the resistance at the interface of the work pieces Rweld should be high enough to form a good weld while the resistance beneath the electrode Relectrode should be as small as possible to avoid electrode sticking. Different types of power supplies are available for providing the welding power .
Suitability of resistance spot welding for connecting battery cells The suitability of a metal for resistance spot welding depends on its thermal conductivity and its melting point , , . Less heat input and thus less welding power is needed for metals with lower thermal conductivity and melting point.
