Using component-adapted, innovative joining technologies, final product properties and lifespan cycles can be significantly improved. This results, for example, in new fabrication approaches, highly productive manufacturing technologies and unique machine solutions.

  • Use of new brillant solid-state lasers for welding conventionally non-weldable metallic mixed joints
  • Multipass narrow-gap welding
  • Laser welding with buffer material, e.g. heat exchanger Cu-tube-steel bottom
  • Welding of Li-battery contacts
  • Spatter and pore-reduced laser beam welding
