System for the electron bombardment welding of cylindrical coaxial rings placed end to end
Description
The system described is for the electron bombardment welding of cylindrical coaxial placed end to end. It includes in combination a carrier trolley for a gun firing a beam of electrons which hits the surface of the shells at their point of junction, a system to propel the trolley, an adjustable device to position the trolley against a bench mark scored on the surface of at least one of the rings, a containment applied against the rings on both sides of their point of junction and marking with them a sealed vacuum chamber containing the trolley. The movement of the rings is of an amplitude equal to and a sign velocity opposed to that of the trolley so that the trolley remains immobile in space in a given position so that the electron beam provided is permanently vertical

On presente un dispositif de soudage par bombardement electronique de viroles cylindriques coaxiales placees bout a bout. Il comporte en combinaison un chariot de support pour un canon fournissant un faisceau d'electrons venant frapper la surface des viroles selon leur ligne de jonction, des moyens d'entrainement relatif du chariot, un organe de positionnement reglable du chariot par rapport a un repere porte par la surface d'au moins une des viroles, une enceinte appliquee contre les viroles de part et d'autre de leur ligne de jonction et delimitant avec celles-ci une chambre etanche placee sous vide et contenant le chariot. Le deplacement des viroles presente une amplitude egale et une vitesse de signe oppose a celui du chariot, de telle sorte que le chariot reste immobile dans l'espace dans une position choisie telle que le faisceau d'electrons fourni soit en permanence verticalAdditional details
