3D Wobble Welding

Types of Laser Plastic Welding: 3D Wobble Welding

3D wobble welding is a special welding process for large 3D components. Using additional amplitudes in a quasi-simultaneous welding process, the laser beam is deflected in a looped shape perpendicular to the feed direction, thereby making it possible to produce different weld seam widths between 1 mm and 5 mm with particularly homogeneous temperature distribution. Local tolerances are balanced out while the machine-specific software automatically activates the wobble function and calculates uniform energy input levels, even when there are differences in height.

Main applications:

Welding large 3D components with a variable weld seam width, e.g. taillights in cars

Main characteristics:

  • Patented, newly developed high-performance welding system
  • For series production of plastic components up to 1000 mm x 750 mm in size
  • The weld seam width can be infinitely adjusted from 1.5 mm to 5 mm
  • Flexibility in the Z direction: height differences up to 400 mm
  • Following the welding process through seam monitoring
  • Very short cycle time
  • Robust process
