High-end laser welding technology developed by GEFASOFT
A2A® PLASTIC WELDING
The A2A® (Absorbent to Absorbent) plastic welding process is a pioneering method in the field of laser welding for plastics. As an experienced machine manufacturer, GEFASOFT has developed its own patented technology in which two laser-absorbent joining partners are bonded directly to one another.
Particularly with regard to design freedom and expanded areas of application, the process offers significant advantages over classic laser transmission welding.
With A2A®, companies rely on a future-proof technology that sustainably increases efficiency, process stability, and versatility in plastic welding.

Advantages of A2A® plastic welding
TECHNOLOGICAL PROGRESS
- Very high flexibility due to simple tools and fast changeover of component variants
- Low production costs compared to dispensing or screwing processes
- Clean, particle-free process for sensitive applications
- Precise and targeted energy input exclusively into the welding zone
- High process control through integrable image processing systems
- Low maintenance requirements and easy integration into existing production processes
Joining of laser-absorbent joining partners
FUNCTIONAL PRINCIPLE OF
A2A® PLASTIC WELDING
In A2A® plastic welding, two laser-absorbent joining partners are bonded directly to one another. The laser energy is applied specifically to the joining zone, causing the materials to melt locally and creating a homogeneous, cohesive bond.
In contrast to classic processes, no transparent joining partner is required. Additional joining techniques such as gluing or screwing are also eliminated. The result is stable, tight weld seams combined with high process reliability and flexibility in component design.

1
The laser-absorbent joining partners are placed precisely in the workpiece carriers.
2
The joining surfaces are heated in a defined and uniform manner using laser energy.
3
The upper joining partner is moved within the system and precisely aligned with the lower joining partner.
4
The heated joining partners are joined under defined pressure and held in place during the cooling phase.
5
Once the weld seam has solidified, the joined component is ready for removal.
A2A® in practice
TYPICAL
FIELDS OF APPLICATION
