L’invention porte principalement sur un procédé de soudage circulaire entre une première pièce (10.1) et une deuxième pièce (10.2) comportant: - une étape de réalisation d'une première soudure (S1) par rotation, dans un premier sens de rotation, des pièces (10.1, 10.2) suivant un premier angle (A1) inférieur strictement à 360 degrés, - une étape de réalisation d'une deuxième soudure (S2) par rotation, dans un deuxième sens de rotation (R2) inverse, des pièces (10.1, 10.2) suivant un deuxième angle (A2) inférieur strictement à 360 degrés, - de telle façon qu'un recouvrement entre une partie de la première soudure (S1) et une partie de la deuxième soudure (S2) permet d'obtenir une soudure circulaire (S_cir) suivant toute une circonférence de la zone de contact (Zc), malgré la présence de l'obstacle (12) sur le trajet du faisceau d'énergie (14). Figure 7 The invention mainly relates to a circular welding method between a first part (10.1) and a second part (10.2) comprising: - a step of producing a first weld (S1) by rotation, in a first direction of rotation, parts (10.1, 10.2) at a first angle (A1) strictly less than 360 degrees, - a step of making a second weld (S2) by rotation, in a second reverse direction of rotation (R2), of the parts ( 10.1, 10.2) at a second angle (A2) strictly less than 360 degrees, - such that an overlap between part of the first weld (S1) and part of the second weld (S2) makes it possible to obtain a circular weld (S_cir) along an entire circumference of the contact zone (Zc), despite the presence of the obstacle (12) on the path of the energy beam (14).

Stator assembly for steam turbine - has blades, shrouds and rings with common electron beam welds

The stator blades (9) fit into suitably shaped holes in the outer (7) and inner shroud (8) so that the ends of the blades are flush with the shroud surfaces (16). The outer ring (5) and inner ring (6) are then fitted in position so that any radial movement of the blades (9) is prevented. The assembly is then welded together by an electron beam. Four separate passes of the electron beam are used as indicated by the arrows (17), (18) (19) and (20) and the circumferential grooves (21) prevent the trapping of gas during welding. The use of electron beam welding prevents any distortion and eliminates the need for any machining operation after welding.

Electron beam welded protector for e.g. skis - consists of at least two light metal alloy parts

The edges of various objects are protected esp. from wear or impact by the application of a metal section comprising at least one flat, thin part to be applied against the edge or to be inserted in the object and at least one massive part to protect the ridge or rim. These parts are electron beam welded together in a vacuum. The protector is used for protecting sports goods such as tennis racquets, and skis against wear. Complex sections can be made from a light metal alloy.

Method for electron beam welding (dot matrix)

ABSTRACT OF THE DISCLOSURE METHOD FOR ELECTRON BEAM WELDING This invention concerns a process of welding by an electron beam. The process is one in which the beam is rapidly deflected from point to point of a predetermined matrix of spots over which the beam rests for predetermined lengths of time in order to produce a predetermined distri-bution of energy over a defined area along the surface of the material being welded along a seam formed at the adja-cent edges of workpieces. The length of time the beam is maintained at each position and the total beam power may be varied from spot to spot in order to produce a desired distribution of energy over a given area. This process is useful to avoid defects in partial penetration welds and in the welding of joints in which the gap between the edges to be welded may approach the diameter of the electron beam. The method is also useful in avoiding defects which may normally occur at the beginning and end of a weld seam.
