6 FAQs about [Resistance energy storage welding 22000 joules]
What is resistance spot welding?
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.
How does welding energy affect electrical contact resistance and tensile force?
Further increasing the welding energy leads to electrode sticking and significant expulsion of bulk material , , , . Fig. 6. Electrical contact resistance and ultimate tensile force as function of welding energy.
Can a battery be compacted using one-sided resistance welding?
For the case of compacting the battery, using one-sided resistance welding, various variants were analyzed numerically, i.e. the impact of welding cycle parameters and technological parameters. Analysis of the results allowed for the formulation of several of the following important conclusions: 1.
How does power source affect welding current?
The energy source will behave differently based on the power supply from the capacitor, i.e. one in which the power source is a voltage source. For the latter case, an increase in resistance (greater length of tungsten electrodes) in the current flow circuit will result in a decrease in the welding current.
Does reducing the length of a shunt increase a weld diameter?
Higher current causes more intense heating and thus plasticizes the shunt material. Contrary to expectations (for a shunt made of copper and thickness of 0.1 mm), reducing the length of the shunt's indentation does not bring the expected negative effects. The opposite effect is obtained in the form of an increased weld diameter.
Does reducing the length of a connector increase the weld diameter?
The results obtained are a bit of a surprise. Analyzing the diameter of the weld, a slight increase was found for cases of reducing the length of the connector. The weld diameter increased to approx. 14% for variant 12 (table I, line 12) for the zero value of the connector (Fig. 8).
