Laser Welding for the Automotive Industry
With the decreasing cost of laser equipment and the widespread adoption of new energy vehicles (NEVs), laser welding has become the preferred choice for critical structural components (e.g., body frames, battery enclosures, and electric motors) in NEVs and high-end vehicle models. This is due to its advantages of high strength, high precision, minimal deformation, high efficiency, and compatibility with diverse materials.
Body and frame welding
In automotive robotic welding, robotic laser welding — empowered by robotic arm welding’s flexible precision — joins roof and side panels, door frames, body floor panels, and other structural components. This process enables welding of dissimilar materials (aluminum alloy, high-strength steel, carbon fiber composites), creating uniform, high-strength welds that enhance the vehicle body’s overall performance.
Engine and Transmission
In automotive robotic welding scenarios, robotic laser welding is used for precision welding of gears, cylinder blocks, and shaft parts (e.g., turbocharger blades, fuel injection components) — leveraging robotic precision to ensure high sealing and thermal resistance.
Power Battery
Galvanometer laser welding enables rapid, precise joining of battery tabs and casings, minimizing thermal impact on lithium-ion cells to support production of high-energy-density batteries .
