Sheet metal part prototyping

The agile organisation and the wide variety of know-hows within ALSENAM makes it possible to produce single metallic parts, such as propotype or mini-series. ALSENAM produces prototypes designed by its customers, but also advises them during the design phase.

ALSENAM accompanies several schools and research centres, contributing to the early stages of their projects, with its expertise in sheet metal work, boilerwork and welding.

Repair, MRO

ALSENAM helps its customers with their part appraisal and repair requirements. ALSENAM advises on the choice and implementation of destructive and non-destructive testing (dye penetrant, X-ray, dimensional, leak testing) and carries out repairs on a wide range of materials: stainless steel, inconel, titanium, aluminium, etc. ALSENAM works on welding, dimensional conformity adjustments, straightening, element replacement (clamps, bossing, fins, etc.), milling repairs, riveting assembly, nitrogen insertion, and the control of the specific subcontracting chain.


Réparation, MCO, MRO

ALSENAM accompagne ses clients dans leurs besoins d’expertise et de réparation de pièces. ALSENAM conseille sur le choix et mise en œuvre des contrôles destructifs et non destructifs (ressuage, radiographie, dimensionnel, étanchéité) et assure la réparation sur une large gamme de matière : inox, inconel, titane, aluminium… ALSENAM intervient sur le soudage, la mise en conformité dimensionnelle, le redressage, le changement d’éléments (brides, bossages, ailettes…), la reprise d’usinage, l’assemblage par rivetage, l’emmanchement à l’azote, et maîtrise la chaîne de sous-traitance spécifique.
