DESCRIPTION OF THE INVENTION
The present invention concerns welding. p? r means of an electron beam, of aluminum alloys, in general, and more particularly concerns a welding material for welding by means of an electron beam; to the welded parts, using a welding procedure by
electron beam; to an electron beam welding process; as well as the use of the welding material, the welded piece and the welding procedure. M. Brillant and Y. de Bony indicate in the article "Le

welding procedure, where the first data on this object are from 1956. The document mentioned above describes the applications of electron beam welding in aluminum alloys. RBF: 23813
It is now known that electron beam welding of aluminum alloys is accompanied by the formation of silicates, which are the origin of fissures during the cooling / solidification phase. These cracks are unacceptable due to the fact that they are incompatible with the fatigue requirements experienced by the welded structure. It is an object of the applicant to propose a solution to this main problem of electron beam welding of aluminum-magnesium-silicon alloys. According to the invention, the welding material for electron beam welding, which is a material of an aluminum-magnesium-silicon alloy of type 6061, is characterized in that the aluminum-magnesium-silicon alloy material has a relation R of content Mg / Si whose value is greater than or equal to the value of the stoichiometric ratio. According to another characteristic of the invention, the piece welded by means of an electron beam soldering process, by means of the use of a welding material, in an aluminum-magnesium-silicon alloy material of the type 6061, where the piez soldered is characterized in that the material of the aluminum-magnesium-silicon alloy has a ratio R of Mg / Si mass content whose value is greater than or equal to the value of the stoichiometric ratio.
According to another characteristic of the invention, the electron beam welding process, by means of a welding material, in an aluminum-magnesium-silicon alloy material of the type 6061, is characterized in that the aluminum-alloy material magnesium-silicon has a ratio R of mass content Mg / Si whose value is greater than or equal to the value of the stoichiometric ratio: a. The welding material, the weldment and the welding process of the invention also satisfy the characteristic according to which the value of the ratio R is greater than or equal to 1.75. According to another characteristic of the invention, the welding material, the welded part and the welding process find use in the railway domain. An example of use includes the realization of the chassis of the cart (bogie), especially for the tube / stringer assembly. An advantage of the welding material and of the welding process of the invention is that it allows the electron beam welding of the aluminum-magnesium-silicon alloy of type 6061, in all cases in consideration, in particular in the case of pieces of a large thickness, on a circular joint and with a coating that produces two successive mergers.
Other objects, characteristics and advantages of the invention will become apparent after reading the description of the welding material, of the welding part and of the welding procedure. The series of alloys 6000 is characterized by the formation of the compound defined Mg_Si which, placed in the joints of the grains, allows, after thermal treatment, to obtain the mechanical characteristics of the alloy. The quantities of the elements allowed by standard NF A 50-901 allow obtaining an alloy with presence of Mg_Si and an excess of silicon or an alloy with presence of Mg-Si and an excess of magnesium. In the case of an excess of silicon, there is formation, in the thermally affected area or in the molten zone, of silicate elements comprising the formation of fissures. Conversely, an excess of magnesium does not have negative consequences on the good state of the solder joint. The solution, in accordance with the present invention, consists in preventing the formation of the silicate and therefore consists in the fact that all the silicon elements are aided by magnesium to form the defined compound Mg2Si. This condition is achieved in the case of alloy
of aluminum-magnesium-silicon of type 6061 if and only if the value of the ratio R of the contents in mass of Mg / Si is greater than the value of the stoichiometric ratio. The material for welding, for welding by electron beam, where the material for welding is an aluminum-magnesium-silicon alloy material of type 6061 and is such that the material of the aluminum-magnesium-silicon alloy has a relationship R of mass contents of Mg / Si whose value is greater than or equal to the value of the stoichiometric ratio. The piece welded by means of an electron beam welding process, by means of a welding material, into an aluminum-magnesium-silicon alloy material, of the type 6061, is such that the material of the aluminum alloy- magnesium-silicon has an R ratio of Mg / Si mass contents whose value is greater than or equal to the value of the stoichiometric ratio. The method of welding by electron beam, by means of a material for welding, into an aluminum-magnesium-silicon alloy material of type 6061, is such that the material of the aluminum-magnesium-silicon alloy has a ratio of content in Mg / Si mass whose value is greater than or equal to the value of the stoichiometric ratio. The welding material, the welded part and the welding process of the invention satisfy
also the characteristic according to which the value of the relation R is greater than or equal to 1.75. The material for welding, the welded piece and the welding procedure find a use in the railway domain. One use of this type comprises the realization of a bogie chassis, especially for the tube / stringer assembly. It is noted that, in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it refers.
