Mask welding
Mask welding is the fastest and most accurate laser welding process on the market, as it allows most complicated patterns to be welded in seconds of time
With this Leister patented technique a mask is inserted between the laser source and the parts to be welded.
A curtain or collimated laser beam is moved across the entire joining area of the parts. The laser beam is only incident on the components where they are not obscured by the mask. The mask makes it possible to project extremely fine structures in the order of micrometers. Mask welding therefore achieves a very high resolution. The most diverse welding seam structures can be produced with mask welding - for example straight and curved weld lines of different width, as well as two-dimensional structures - all in a single operational step.
Mask welding developed by Leister was granted the Swiss Technology Award 2000.
Characteristics and application:
- Line-shaped laser beam
- Any desired joining geometry within a plane
- Fast and flexible
- Very fine 2D joining structures
- Suitable for micro and macro applications
