EMAG Automation: Complete laser welding solutions for transmission manufacturing


In the automotive industry, one trend has been consistent for years: Passenger vehicle transmissions are becoming smaller and lighter, although the number of speeds—and of toothed gear components—continue to increase. How does the entire assembly not become heavier? The answer becomes obvious by taking a closer look at the individual components. A gearwheel, for example, consists of two components that are joined by laser welding. This allows the design engineers to work without screws—allowing the component to become lighter.
