AbstractAbstract
[en] 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
[fr]
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 verticalOriginal Title

AbstractAbstract
[en] Adopted initially by the nuclear and aerospace industries, electron beam welding is now used world-wide in many applications. Since its inception, power and penetration levels have been increased by over an order of magnitude, but intensive R and D continues to keep abreast of ever-increasing industrial expectations. Equipment and process developments are reviewed in this article. (Author)

AbstractAbstract
[en] The paper describes theoretical and experimental results, regarding electron beam welding of different large thickness of high temperature steel materials. The results show, that beam deflection and oscillation pattern contribute to a high extent to welding depth and quality of welding seams

AbstractAbstract
[en] Focalized ultrasonic testing is well adapted to the study of electron beam welding. This type of welding leads to narrow weld beads and to small dimension testing zones. Focalized transducers can be used enabling very small defects to be detected
[fr]
Dans le cas de soudures obtenues par bombardement electronique, le controle par ultrasons focalises est particulierement adapte. En effet, ce type de soudure conduit a de cordons etroits et pour de nombreuses geometries d'assemblages a des zones a controler de petites dimensions. Ceci permet d'utiliser des transducteurs focalises de tache focale de faibles dimensions, ce qui permet une detection et un dimensionnement de defauts tres petitsOriginal Title

AbstractAbstract
[en] The electron beam welding process is described and the unique mode of operation and penetration explained by a description of the forces operating within the weld pool. This penetration model is demonstrated by high speed cinematography of the weld pool on several materials. The conditions under which weld defects are formed are discussed and examples are presented.

AbstractAbstract
[en] The principles, advantages, and disadvantages of electron beam welding are summarized. Two applications of the method to fuel assembly production are the electron beam welding of end plugs for the Mg-Zr fuel cans in the Bugey-1 reactor and for anchorage welds to maintain the fuel plate of the Grenoble High Flux Reactor in position in the assembly. Based on this experience a system was developed for on-site welding of heavy plate sections of stainless steel. (U.K.)
