Assembly techniques are critical in designing and building products and systems. Mastering assembly techniques is essential either directly on account of the need to make different materials interdependent or for meeting restrictions in terms of weight, cost, ease of use, etc.
ALCEN excels in this domain both by its knowledge of different types of expertise, often trough ownership of the solutions, and by the broadband of its expertise.
ALCEN masters permanent assembly by welding solid parts, fine sheets metal or piping in, aluminum, titanium or stainless steel, including welding on thin walls, a few tenths of a millimeter thick, by laser, electron beam or the conventional TIG process.
Similarly, metallic materials or dissimilar metallic / ceramic materials can be associated by brazing or by diffusion welding (vacuum, salt-bath, flux, etc.).
All the interest in reducing weight by using composite materials has led ALCEN to study the behavior of hybrid composite/metal assembly.
Assembly by bonding is a component integrated within ALCEN, for metal/metal or hybrid bonds and for rare materials such as syntactic foams.
Furthermore, to meet maintenance and/or normal control restrictions and requirements, ALCEN regularly proposes engineering concepts that call on demountable nut/ bolt assemblies. For many decades, riveting and its countless configurations have been one of the Group’s strong points.
However, for simplification or reliability purposes, ALCEN also proposes systems where assemblies have been eliminated and replaced by the use of cold forming processes (drawing, hydroforming, etc.) for obtaining more “single-piece” parts.
Our assembly procedures, our non-destructive means of dimensional control validate and guarantee the assembly’s integrity.
