6 FAQs about [Battery welding current calculation]

What are the different welding techniques for batteries?

The purpose of this project is to conduct a comparative literature study of different welding techniques for welding batteries. The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality.

What is the maximum current of a battery Weld?

ximated from the battery welding station of one of the manufacturing companies. The maximum value of current was 2.2 kA.For a change in the current value in the range of +/- 10% from the maximum value, i.e. 2.0/2.4 kA, the weld diameter is reduced by 55% and increased by 60%, respectively,

How do you Weld a battery?

The search was then performed using Uppsala University’s Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.

Is UWB suitable for welding a cylindrical battery cell?

UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.

Why is parameter control important in battery cell welding?

Parameter control also allows LBW to adapt to the thickness of the material tabs and can create thin or thick weld nuggets. In battery cell welding it is important to create thin welds due to the relatively thin battery cases and the risk of the weld penetrating the case and thus damaging the core.

How do you calculate the impedance of a weld?

Figure 2: Simple weld resistance circuit. The impedance of the weld is then calculated using Ohm’s Law. The impedance of the weld is typically very low, on the order of milliohms to microohms. Therefore, it’s important that the current source is wired separately from the voltmeter.
