Advantages 3 D Laser Hybrid process
Stainless Steel Structurals SWS March 2014
The 3D Laser-hybrid welding combines the advantages of laser fusionand arc welding (MIG/MAG)
- Reduced distortion due to little heat load- Deeper binding penetrations- Good gap bridging ability at high process speeds- Excellent weld seam quality- Increased performance and energy efficiency- Increased process stability
Gap bridging & complex geometry

Free Geometry
These advantages are integrated onto the 5-axis robot, which
ensures extreme binding precision, accessibility tochallenging binding positions and non-linear geometries withcurves and variable heights. Also components where thejunction angle of the different part is different from 90 degreecan be assembled and fused together.
