6 FAQs about [Energy storage bolt welding method]
Which welding methods are used in the production of battery applications?
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. All three methods are tried and proven to function in the production of battery applications.
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.
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 a battery work?
Under the electrode pressure and during the welding current flow, heat is generated on the system resistances, which results in welding of the battery components [12÷14]. An example of a battery after peel test of the connector with its visible parts on the battery housing is shown in figure 1a.
What parameters are changed during a spot-welding process?
The three primary spot-welding process parameters that are changed are welding time, welding current and electrode force. The welding time during RSW is very short, it varies between micro- and milliseconds. Too short of a welding time or a low applied electrode pressure may provide insufficient surface contact and lead to a poor weld.
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.
