What has changed?

improved distribution network new technologies availability of small quantities complete size range

Yesterday

Today

few suppliers long delivery time limited size range limited know how irregular consumption

This evolution enables architects and engineers to plan & design freely with

stainless steel like they use to do with carbon steel.

And what is LASER-FUSION in

3D

?Stainless Steel Structurals SWS March 2014


19/58

A 5-axis robot allows the production of non-linear sections andfabricated components

3D Laser cutting 3D Laser welding



20/58

Advantages 3 D Laser-fusion


- High quality of weld seam (fusion)- Low residual stress in component- High accuracy and tolerances on component- Free geometry and weld position setting- Reproducibility- Low oxidation- Limited weld splatter- Good mechanical properties of the seam (fusion)- Very small heat affected zone

27/58

Advantages 3 D Laser Hybrid process


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


28/58


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.
