Product description

Multi technology solution
We designed, in close collaboration with the customer project team, a sensor body that was subject to a severe environment inside exhaust catalytic converters.
- Temperatures in excess of 1000°C
- Highly corrosive atmosphere

The optimal solution was obtained by including machining related technology
- Laser welding
- Deep drawing
- Use of refractory materials (inconel,...)
- High speed automated assembly (cam lathes)

Laser Welding
Value analysis led us to propose a technical-economic solution based on three components assembled using laser welding.

Thanks to our collaboration with laboratories and technical centres we were able to recommend the adapted materials.

A high number of prototypes were made in order to validate the feasibility and the industrialisation study.
Complete analysis of issues encountered during welding.

Highlighting of fissuring problems using SEM.
Process modified to take this into account.
Fissures solved by the correct choice of source

Small transverse drilling without burrs

Hydraulic component issues: - No burrs! - Very low surface state tolerances - Water tightness requirements This issue is especially relevant for fine drilling with diameters of less than 0.15. When drilling fine cutting holes the burr issue is essential and is a difficult issue to solve. Generally ...read more
