Got Copper? Weld it. Join it. Heat it.

Batteries are making headlines everywhere recently. Mostly, it is because auto manufacturers from BMW to Tesla to Volkswagen are all introducing EV models as fast as they can build them. All those EVs require batteries. A lot of batteries.
All the new electric vehicles are powered by battery packs based on cells like the 18650, 2750 and others. Every pack requires welded copper tabs connecting one cell to another. Traditionally the welding and the joining of other metals to copper is done with ultrasonic welders, spot welders, or IR lasers. However, our solution is better than any of those typical solutions. Here's why...

Copper absorbs certain wavelengths of light better than others. While up to 90% of IR light can be reflected by copper, we've found that blue (455 nm) laser light is readily absorbed by copper. We developed the ClearCut laser for those battery manufacturers and materials processors specifically to take advantage of that absorption.

Depending on the material, the ClearCut is up to 20 times faster and more efficient compared to traditional joining lasers and ultrasonic welders. The ClearCut provides better wall-plug efficiency and lower maintenance costs. It is easy to integrate into other applications thanks to its air-cooled architecture. No external water chiller or liquid cooling is required. With powers from 26 Watts to 100 Watts, manufacturers can tailor the exact configuration for their application.

Our VP, Walter Burgess, put it pretty well. He told me "the need for better copper processing is being driven by the rise in electric vehicles and other battery-hungry applications. Manufacturers and processors needed a faster and more efficient way to work with their materials. The ClearCut laser was designed to meet those needs."

The ClearCut laser brings wavelength and power optimizations to materials processing applications that are ideal for the automotive industry, electrical vehicle battery pack manufacturing, aerospace, welding, wire bonding, and additive manufacturing (3D printing) applications.
