Laser welding system is easily integrated
The StarWeld series of pulsed YAG lasers, fitted with dynamic beam positioning offers an easy package to integrate into production automation equipment for the automotive and other industries.
Dynamic performance from welding system
The StarWeld Dynamic from Rofin-Baasel is a turnkey laser welding system, ideal where positioning speed and accuracy are critical.
Using any of the diode lasers or diode-pumped YAG lasers of the StarWeld series.
Three different wavelengths of laser source are provided by Rofin-Baasel (808, 940 and 1064nm) allowing solutions to be found in a wide range of applications.
Dynamic beam positioning allows the laser weld profile to be achieved without motion of the component to be welded, simplifying fixturing and clamping of the component.
Laser welding is a comparatively new technology in the joining of thermoplastic polymers and offers a range of advantages including: superior optical quality of the weld; nonporous surface quality; minimal surface contamination (no debris); minimal thermal stress of the component (minimum heat input); high tear-resistance of the weld; and no vibration introduced into sensitive electronic assemblies.
In almost all cases the overlap joint configuration is used.
The top layer of material is transparent to the laser beam and the bottom layer absorbs the laser energy to form an invisible weld bead at the interface of the two layers.
A wide range of polymers including PP, ABS, PBT, PA and PC can be welded provided attention is paid to the absorption behaviour of the material at the wavelengths of light used.
In most cases, theoretical evaluation is not enough and practical trials are recommended. Request a free brochure from Rofin-Baasel UK ...
