The Mecaweld (fabrication / sheet metal work) division was created to bring together the long experience and know-how of the companies Ventana Argenteuil and Alsenam.
These skills are distributed over 4 sites: Argenteuil (95), Mérignac (33), Narcastet (64) and Sousse (Tunisia).
The Mecaweld division designs, develops, manufactures and repairs complex mechanical subassemblies using a wide variety of processes:
Fine sheet metal work, mechanical welding, stamping, punching, bending, sheet metal work, piping, machining, Electro-Discharge Machining, laser welding and cutting, heat treatment, penetrant testing …
Ventana MecaWeld operates mainly in the Aeronautics & Space and Defense sectors.
Due to the great diversity of processes integrated in its workshops, VENTANA MECAWELD is ideally positioned to carry out projects for the production of complex welded parts.
The metals and alloys shaped are aluminum, stainless steels, superalloys, nickel,inconel, titanium, copper, brass, Mumetal, cobalt, tantalum …
The technologies implemented include engineering and industrialization, cutting, sheet metal work, stamping, bending, heat treatment, welding (TIG, Laser, by resistance by points), bending, assembly and NDTs.
Partner of major aeronautics contractors, VENTANA MECAWELD produces subassemblies of aerostructures, from the simplest to the most complex.
VENATANA MECAWELD has long-standing expertise in the use of hard metals for the production of hot parts, in particular engine parts: engine support, nozzle, exhausts, combustion chamber, heat exchangers
Founded in 1956, VENTANA MECAWELD ARGENTEUIL is the historic site for fabrication in the VENTANA group. Its location allows its engineers to be as close as possible to the major aeronautics and space contractors. this facility is designed for large industrial projects.
Founded in 1966 and integrated into the Ventana group in 2020, the Narcastet plant is recognized for the design, manufacture and repair of high added value parts. These products are mostly made of stainless steel, titanium or refractory alloys, for industry or engine manufacturers in aerospace business
Founded in 1976 and integrated into the Ventana group in 2020, Ventana MecaWeld Merignac specializes in complex mechanical subassemblies through the bending and assembly of tubes and thin sheets, for aerospace and defense.
Founded in 2008 and integrated into the Ventana group in 2020, Ventana MecaWeld Sousse employs now 30 persons. This site has been certified as per EN9100 and has all the skills to produce complex products in large series.
