Advantages Torsional thin wall welding

Thin wall welding with Telsonic torsional welding process compared to alternative technologies, such as linear ultrasonic welding, gluing or laser welding:

  • Significant savings in overall costs due to less use of materials, no expensive additives, less wear on tools, low energy costs
  • Significant weight saving because components can be designed with a thinner wall
  • No marking on already painted parts (Class A surfaces) 
  • Fulfillment of highest OEM quality requirements
  • High tensile strength (400N)
  • Short cycle time (welding time around 300ms)
  • High flexibility in component design
  • High process stability
  • Low integration effort into different automation concepts
