Ariane 5 production. Engineers supervising the welding of a fuel tank for an Ariane 5 launcher. The tank is made of 3mm-thick aluminium. The welding device (star-shaped object at centre) rotates inside the tank,allowing a continuous,seamless weld to be made. The integrity of the weld is crucial,as the cryogenic tanks form the load-carrying structure of the first stage of the launcher. The stage contains two tanks,one for liquid hydrogen and the other for liquid oxygen,sharing a common bulkhead. The interior of the liquid hydrogen tank is seen here.
