Invisible plasma welding


The SPE 005 patented welding

Plasma welding combined with a specific finish, has been patented by Conimast International.
This new technology, applied to lampposts with a circular and conic polygonal section, considerably improves the aesthetic quality of our products.

The welding process without filler material, which involves joining the edges of the lampposts in a weld puddle, offers two major advantages :

  • the weld ridge is no longer prominent
  • the weld ridge is homogeneous

SPE 005 welding provides a finish similar to extruded metal. In addition to its aesthetic quality, the robustness of the steel offers more design possibilities.
