ALO4 | 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.
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. The additional wire thus forms a wear-free, self-renewing guide tip – directly at the focus of the laser and with consistently high accuracy.
Areas of application
- Laser brazing and laser welding
- Steel and aluminium alloys
- Y-seam at the flare joint
- Fillet welds at the lap joint
- Fillet welds at T-joint
Advantages
- Stable process control and highest seam quality through automatic compensation of component tolerances by tactile seam tracking with filler wire.
- Various sampling positions (left / right applications) and different seam geometries are possible in one station thanks to the parametrisable motorised lateral adjustment.
- 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 confifiguration thanks to the modular scapacs® system and expandability over the entire product life cycle.
Supported Laser
- Diode laser
- Solid-state laser like rod laser, disk laser, fibre laser
