Applications in the Manufacture of Electric Vehicles

Significantly more electronic components are used in electric vehicles than in conventional vehicles. Copper welding with blue diode lasers allows copper pins and sheets to be welded to small motors or battery contacts, for example. Another important application is the laser drying of battery foils with large laser spots. The aluminum welding of large battery boxes covers another application in electric cars.

Laser heating and drying is an innovative application of laser light that projects a laser beam over a wide area to heat and dry target materials. The power density of the beam is typically lower than that of the comparatively focused beams used for other materials processing applications like cutting and welding. The size of the projected light is easy to control, allowing for targeted application of heat that virtually eliminates the waste heat generated by traditional heating methods.

Laser heating is a highly efficient and sustainable method of heat treatment for a variety of applications including battery foils, powder coat, and paint drying. Faster than traditional convection furnaces and more energy efficient than infrared lamps, laser heating and drying solutions offer a unique combination of high throughput and low operating costs.

Advantages of Laser Heating & Drying

● Extremely high energy efficiency up to 55%​；

● Targeted heating – lasers direct energy only onto the targeted area and do not radiate waste heat into the factory​；

● High-speed process up to 10X faster than convection furnaces​；

● Laser heaters are “cold” furnaces that support in situ metrology​ for precise process control

● Non-degrading performance – laser heating offers consistent, long-term results with no consumables like infrared bulbs​.
