Laser surface treatment machine for Ariane 6 Cryogenic Tanks
Surface treatment of cryogenic tanks (liquid oxygen and liquid hydrogen) for the Ariane 6 Space Launcher is a critical step for the adhesion of insulation materials. This operation is currently performed by the help of chemical products which are for some of them carcinogenic, mutagenic and repro-toxic. The large tank dimensions require using an important quantity of those products which generate massive recurring costs and health and environment problems. ArianeGroup has previously qualified and patented the Laser Surface Treatment as a replacement solution to chemical process. The aim is to use energy provided by infrared laser beam to modify the top layer of the tank surface. The chosen technology is Nd-YAG pulsed laser. Electroimpact has been chosen to carry out the industrial application.
