E-mobility made with TRUMPF Laser

We help to drive the future.

TRUMPF lasers open up a wide range of manufacturing options to the automotive industry in all areas of electro-mobility, paving the way for a mobile future. From high-end laser systems with the highest beam quality, to intelligent quality assurance systems, right up to the construction of complete production systems: in the field of e-mobility, TRUMPF is your reliable partner. With our extensive industry and application expertise, as well as our global laboratories, we help the sector to understand new technologies. In numerous projects and initiatives, together we develop solutions for the upcoming challenges posed by electro-mobility. Here, we get involved in the entire development process, from the initial idea to the start of production.


TRUMPF offers forward-looking solutions in laser-based production of electrical drives, especially in the process of assembling hairpin stators.

Differential gears

TRUMPF lasers enable the reliable, high-quality mass production of differentials for light-weight construction e-cars.

Low-spatter copper welding

New processes and lasers in the green wavelength range allow precise and reproducible laser welding of copper with minimal spatter.

Battery production

TRUMPF has developed industrial-suited technologies for laser welding and laser cutting of a wide variety of components in battery systems in electrical vehicles.


More than 500 beam sources sold in worldwide battery production.


Around 50 million differentials are manufactured annually using laser technologies.

97 %

Up to 97% less spatter thanks to copper welding with green laser light.

Innovative E-mobility applications

Welding of hairpins during production in the electromobility field

Electric drives: Hairpin welding

To prepare hairpin welding, our customers use TRUMPF short-pulse lasers that remove the insulating paint coating without damaging the copper below. The process delivers more precise results than mechanical coating removal processes. Intelligent sensor systems ensure precise seams when welding the hairpin thus ensuring optimum quality. Thanks to the high reproducibility of the laser welding processes, our customers achieve consistently high-strength connections with good conductivity - and they do so in large quantities as well.

Butt joints in gear manufacturing

Welding of differential gears

TRUMPF lasers weld the housings of differential gears with bevel gears reliably, flexibly, and without contact. Here, they enable the creation of numerous hybrid material connections for lightweight design. The most  common of these is the combination of cast iron and case-hardened steel. The highly precise joining technologies using lasers also help to considerably reduce unwanted running noises from the differential gear during operation.

Copper welding with a laser

Spatter-free joining of copper and aluminum

Due to increasingly compact casings and the required higher conductivity of electronic components, the requirements for the joining technology of copper and aluminum components also increases. A newly developed, pulsed green laser from TRUMPF welds these materials with high reproducibility and eliminates almost all spatter - irrespective of the condition of the surface.

Seam weld on a cell phone battery

Connection of battery cans

TRUMPF lasers are ideal for sensitive battery cells and their casings, the cans, as they operate with no contact and with almost no energy input. The material is not subjected to mechanical load. The locally limited, low heat input caters for high-precision, distortion-free seams.

Manufacturing of battery cells with TRUMPF lasers

Welding of battery casings

With TRUMPF lasers, customers weld battery casings and cell connectors of copper and aluminum easily and with precise seams. Increasingly small and powerful cells are integrated in this manner in a battery array. An extensive system of sensors monitors the quality of the welding seams and guarantees precise welding penetration depth.

Laser-cut stator plates

Cutting of stator plates

Manufacturers of electrical motors use TRUMPF lasers for cutting stator plates. Delicate contours can be cut very quickly and precisely. Our customers profit from high reproducibility and the lack of distortion, even when joining stator packages in prototype construction.

Always at the cutting edge of research

TRUMPF is actively involved in phase three of the Lightweight Forging Initiative. Around 40 international partners have been investigating for more than five years areas such as the lightweight potential of radically redesigned components in powertrains as well as chassis-and-suspension systems of hybrid cars. TRUMPF is also involved in many other development projects on new eMobility applications and on lightweight design for a forward-looking, resource-efficient electric mobility.
