ALO4-O | Laser welding and brazing with tactile seam tracking

Equipped with numerous new features, the processing optics are even more flexible in use and optimized for the automated processing process.

ALO4-O | The new generation of Laser welding and branzing with tactile seam tracking

Function description

The filler wire required for the seam during joining also serves as a mechanical sensor. The filler wire is continuously pressed into the joint by the swivel axis and melted in the laser focal point; it positions and guides the processing head precisely over the seam.

Two synchronized scanner axes are integrated into the ALO4-O for a defined 2D laser beam oscillation with up to 1000 kHz. Beam oscillation is a repeated, high-frequency movement of the laser beam. Deflection shapes, amplitudes and frequencies are freely programmable for each scanner axis.

Areas of application

  • Laser brazing and laser welding.
  • Steel and aluminium alloys.
  • Thick sheet metal applications, alloying with additional material and seam smoothing.

Advantages

  • Stable process control and highest seam quality through automatic compensation of component tolerances by tactile seam tracking with filler wire.
  • Definable 2D laser beam oscillation with up to 1000 kHz via two synchronized scanner axes. Deflection shapes, amplitudes and frequencies can be freely programmed for each scanner axis.
  • Industry 4.0 as the new standard for connectivity and intuitive user interfaces with recipes for operating and configuring the optics.
  • SCeye® system for highly automated and intelligent process monitoring, as well as for recording all videos and data from the process.
  • Integrated 3D weight compensation and force control guarantee high-precision control of the wire pressure forces and enable a processing space of 360 °.
  • Shortened start-up times, faster optics changeovers and more efficient service thanks to plug & play in the hardware and interface architecture.
  • Easy handling thanks to the optional integration of external functions such as wire feeder, media control, QA systems and direct control of the laser source.
  • Individual device configuration thanks to the modular scacpacs® building block system and expandability over the entire product life cycle.

Supported Laser

  • Diode laser
  • Solid-state laser like rod laser, disk laser, fibre laser
