Energy storage nickel sheet welding

Why was laser welding used to join nickel sheets?

Laser welding was used to join nickel sheets because it is a non-contact process, which can produce high precision welds and has shorter cycle time. The orientation of the nickel sheet during laser welding was the same as in resistance spot welding.

What is the orientation of nickel sheet during laser welding?

The orientation of the nickel sheet during laser welding was the same as in resistance spot welding. It was found that the sample welded using laser welding has three layers of circles as resulted in Fig. 51.3 d.

Can nickel joint be used for EV battery development?

In this study, the joint ability of two different joining techniques, namely resistance spot welding and laser welding of nickel weld interfaces and joint microstructure were addressed. Similar materials of nickel joint were used to investigate the parallel connection of tab cells for electric vehicle (EV) battery development.

Which welding techniques can be used for connecting battery cells?

Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.

How to analyze welded ni and Ni joints similar materials?

The current research work was focused on the analysis of welded Ni and Ni joints similar materials by using the spot welding process. Three main parameters in spot welding will be used: electrode force, welding current, and welding duration.
