Hi White Paper: Laser Welding Applications with multi-channel high-power fibre lasers.!.
‘Laser welding applications with multi-channel high-power fibre lasers’.;
A multi-channel fibre laser could feed up to four production lines or scan heads inside one or different laser cells.
Modern laser welding applications must provide short cycle times and fast beam guiding.
A four-channel beam switch must ensure identical beam and process parameters at all four fibre outlets, respective fibre connectors.
PRIMES observation with a Microspot Monitor allows control and storage of all relevant data.
The fibre will be connected to a collimation and or to a beam expansion unit. Different control routines before and after collimation enables easier set up.
In this white paper supplied by Laser Trader, measurements in different distances give an overview regarding the collimated beams, the beam quality and the power density distribution before entering the focusing or working head.
Each single optical component will be checked whether the possible impact on relevant optical parameters and finally relevant welding process parameters.
The focus analysis finally mirrors the situation right in the tool centre point. The ‘before’ and the ‘after’ beam parameter products will be measured and documented.
The laser scan heads and adapted F-Theta lenses or even telecentric F- Theta objectives will be checked.
Measurement protocols will be shown, as well as a short overview of the used different diagnostics tools.
