4 FAQs about [Laser welding method for energy storage battery cabinet]

Can laser welding be used for electric vehicle battery manufacturing?

There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing.

Can lithium ion batteries be welded?

It’s a fact that welding a less resistive metal to the standard stainless-steel terminal of a lithium ion battery can reduce resistance and improve battery efficiency. Traditional resistance spot welding, however, can’t effectively join highly-conductive dissimilar metals like copper and aluminum because the resultant intermetallic mix is brittle.

What is a laser weld profile?

Pulsed lasers feature small spot sizes using more weld spots to create the same contact area in a weld zone and ensure appropriate weld strength at the material interface.

Can laser welding improve the shape of a welded joint?

Chelladurai et al. studied the welding of 3 mm 1050 aluminum and 0.25 mm steel sheet. The weld adopted the overlapping structure, the top was thin nickel steel, and the bottom was thick aluminum. They found that in laser welding, adding a wobble to the beam could effectively improve the shape of the welded joint.
