 IPG Photonics Presents:

Integrated Solution for Battery
Module Production

March 13th, 10:10 AM

Continuous and fast migration of the automotive industry to electrification is forcing production strategies towards higher and higher levels of automation and throughputs, of course,
without accepting any compromise in terms of production quality.
This paper addresses the application of busbar welding for the interconnection of individual battery cells into modules. While the principles apply to any cell technology, the examples in this presentation will center around cylindrical cells as they represent the greatest precision and cycle time challenges for the manufacturer.

After summarizing the busbar welding requirements, the paper will review the selection of the principle hardware elements that include laser, beam delivery, vision and weld quality measurement system,
and how each contributes to a high-yield, high speed manufacturing process. The paper will then focus on the integration of these components with a single dedicated system controller and software
interface, and how this “Integrated Solution” greatly simplifies the implementation of a laser welding capability for the automation or line integration suppliers.
