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.
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
