a a. 1" a a Related Art: Name of Applicant: GEC Alsthom Transport SA, Constructions Industrielles De La Mediterranee CNIM Actual Inventor(s): Michel Rimbaud Frederic Liodenot Pierre Gonthier Maurin Address for Service: PHILLIPS ORMONDE FITZPATRICK Patent and Trade Mark Attorneys 367 Collins Street Melbourne 3000 AUSTRALIA Invention Title: A WELDING MATERIAL FOR ELECTRON BEAM WELDING, A WELDING METHOD, A WELDED PART OBTAINED THEREBY, AND USES THEREOF Our Ref 476840 POF Code: 1501/202864,299695 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): -1- -_Roo A WELDING MATERIAL FOR ELECTRON BEAM WELDING, A WELDING METHOD, A WELDED PART OBTAINED THEREBY, AND USES THEREOF The present invention relates in general to electron beam welding of aluminum alloys, and more particularly it relates to a welding material for electron beam welding, to parts welded by means of an electron beam welding method, to an electron beam welding method, and also to the use of the welding material, the welded part, and the welding method.
M. Brillant and Y. de Bony indicate in an article entitled "Le soudage par faisceaux d'6lectrons des alliages d'aluminium" [Electron beam welding of aluminum alloys] published in Mat6riaux et Techniques, ISSN 0032- 6895, August-September 1980, Vol. 68, No. 8-9, pp. 318 to 330, that electron beam welding is a welding method for which the earliest patent on the subject dates from 1956.
The above-mentioned document describes applications of electron beam welding to aluminum alloys.
At present, it is known that electron beam welding 20 of aluminum alloys is accompanied by the formation of silicates which give rise to cracks during the i cooling/solidifying stage.
Such cracks are unacceptable because they are incompatible with the fatigue stresses to which the welded structure is subjected.
It is the merit of the Applicant to propose a solution to that major problem associated with electron beam welding of aluminum-magnesium-silicon alloys.
According to the invention, the welding material for electron beam welding, said welding material being a 6061 type aluminum-magnesium-silicon alloy, is characterized in that said aluminum-magnesium-silicon alloy has a mass content ratio R of Mg/Si whose value is greater than or equal to the value of the stoichiometric ratio.
According to another characteristic of the invention, the welded part welded by means of an electron beam welding method by means of a welding material and a
I

2 6061 type aluminum-magnesium-silicon alloy, is characterized in that said aluminum-magnesium-silicon alloy has a mass content ratio R of Mg/Si whose value is greater than or equal to the value of the stoichiometric ratio.
According to another characteristic of the invention, the method of electron beam welding by means of a welding material and a 6061 type aluminum-magnesiumsilicon alloy, is characterized in that said aluminummagnesium-silicon alloy has a mass content ratio R of Mg/Si whose value is greater than or equal to the value of the stoichiometric ratio.
The welding material, the welded part, and the welding method of the invention also satisfy the characteristic whereby 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 method find a use in the field of railways.
One such use relates to making bogey frames, in "0 "particular for assembling tubes and sole-bars together.
An advantage of the welding material and the welding method of the invention is to make it possible to perform a "electron beam welding of the 6061 type aluminummagnesium-silicon alloy under all circumstances, in particular when the parts concerned are thick, around a circular join, and with overlap producing two successive melts.
Other objects, characteristics, and advantages of the invention appear on reading the description of welding equipment, a welded part, and the welding method.
6000 series alloys are characterized by the formation of the compound defined as Mg 2 Si which, when located at grain boundaries, makes it possible after heat treatment to obtain the mechanical characteristics of the alloy.
-ls~4-w -1 3 The element contents allowed by the standard NF A 50-901 enable an alloy to be obtained in which Mg 2 Si is present together with excess silicon, or an alloy to be obtained in which Mg 2 Si is present with excess magnesium.
When there is excess silicon, silicates form in the zone affected by heat or in the melt zone, which silicates give rise to the formation of cracks.
Conversely, where there is excess magnesium, there are no unfortunate consequences on the integrity of the weld join.
According to the present invention, the solution consists in avoiding silicate formation and therefore consists in ensuring that all of the silicon content is 15 alloyed with magnesium to form the compound defined as Mg 2 Si.
For a type 6061 aluminum-magnesium-silicon alloy,.
•0 this condition is satisfied if and only if the value of the mass content ratio R of Mg/Si is greater than the 0 20 value of the stoichiometric ratio.
0" The welding material for electron beam welding, where the welding material is a material made of 6061 Stype aluminum-magnesium-silicon alloy, is such that the material in the aluminum-magnesium-silicon alloy has a mass content ratio R of Mg/Si whose va&lu is greater than or equal to the value of the stoichiometrio ratio.
S: The welded part welded by means of an electron beam welding method using a welding material made of a 6061 type aluminum-magnesium-silicon alloy is such that the aluminum-magnesium-silicon alloy has a mass content ratio R of Mg/Si whose value is greater than or equal to the value of the stoichiometric ratio.
The electron beam welding method using a welding material and a 6061 type aluminum-magnesium-silicon alloy is such that the aluminum-magnesium-silicon alloy has a mass content ratio R of Mg/Si whose value is greater than or equal to the value of the stoichiometric ratio.
r 4 The welding material, the welded par+, and the welding method of the invention also satisfy the characteristic whereby the value of said ratio R is greater than or equal to 1.75.
The welding material, the welded part, and the welding method can be used in the field of railways.
One such use lies in making a bogey frame, in particular for assembling tubes and sale-bars.
