As the electrification of vehicles continues to grow with the spread of battery technology, the processing of copper and aluminum will be at the forefront in the coming years. Using green-wavelength lasers will be an important tool in this processing revolution. The high absorption into copper, greater than 40%, and its insensitivity to varying surface conditions make the green laser the perfect choice for process stability and flexibility in manufacturing. This is critical in welding battery foils, foils to bus bars, controlling the depth and heat of copper mounted to ceramic insulators, and more. Low heat input, consistent penetration, and lack of spatter are key when welding on a completed electrical circuit because having to scrap that expensive part because of thermal damage or electrical short caused by a piece of spatter from welding is not ideal. As new lasers are developed and processes are enhanced, green-wavelength lasers will play an important part in the growing electrification market.

Other examples include circuit boards, control circuits, and power distribution/charging assemblies; again, process control and heat input are important, but eliminating spatter in these applications is critical. A small spatter ball can cause a catastrophic short in the product, which can damage the part or even create a dangerous situation for people nearby.

Let’s take a look at why the craze about visible-wavelength lasers exists. It all starts with absorption in copper (see Fig. 1); near-infrared (near-IR) lasers only absorb between 1% and 5% of the laser energy depending on the surface condition (polished, oxidized, clean, etc.), while lasers in the visible spectrum absorb around 40–45% of the energy at room temperature independent of surface conditions.

So, where do green wavelength lasers excel? The short answer is conduction welds using copper, thin foil welding of copper, and basically any copper welding application that requires no spatter or need to control heat input and depth, repeatably less than 2 mm deep. Traditional welding typically is about strength and cosmetic appearance—but when it comes to electrification processes, electrical conductivity/low resistance is as important and, in many cases, more important than the strength.

The past three years have seen an explosion in the all-electric vehicle market. This electrification requires very large battery packs with lots of welding applications. Beyond the electrification of motorized vehicles, the need for electronic devices continues to grow at astonishing rates, from home power storage units for house solar panels to industrial power storage units, handheld power storage devices, battery backup units, computers, phones, and tablets. Most of these devices use copper or aluminum, which can be difficult to weld with infrared (IR) lasers, especially thin foils. Until the past couple of years, visible-wavelength lasers were very expensive and not the most robust for high-utilization industrial manufacturing. Now, visible-wavelength lasers deliver high beam quality, industrial stability, and attractive pricing.

Welding thin foil stacks of copper is a perfect application for green lasers. When talking thin foil stacks, we are referring to 5- to 25-µm-thick foils and typical stacks of 10–100 sheets, but any stack of three sheets or greater is ideal. As with all laser welding, gaps between layers are a problem, so clamping methods to remove gaps are critical for a successful laser weld. With an IR laser, a keyhole needs to be established for consistent absorption since the absorption varies greatly throughout temperature variations and the process is so unstable. The keyhole is very volatile and with spatter being ejected, there may be very little molten material to bridge even small gaps, causing upper layers to be cut through and therefore not making good electrical contact.
