Abstract

A rod for electric arc welding has a metallic core of elongated rectangular or elliptical cross-section, with minor dimension considerably less than the major. The core is surrounded by a flux sheath of similar form. Alternatively two circular rods may be enclosed side by side in a figure of eight flux sheath. The rod is used for butt welding sheet material, with its major dimension perpendicular to the facing edges, and the direction of movement when depositing the weld bead. A gap is left between the sheet edges, before welding, wider than the major dimension of the rod. This electrode is suitable for use with thin sheet material, producing a weld free from holes, without burning the edges of the sheet.

Description

La présente invention est relative à une baguette du genre de
celles qu'on utilise pour effectuer de la soudure à l'arc. Elle con
cerne étalement un procédé inédit pour l'utilisation de cette ba
guette.The present invention relates to a rod of the kind of
those used to perform arc welding. She con
also identifies a unique process for the use of this ba
watch.

On sait cu'il est difficile de souder bord a bord deux tôles ou
deux parois metallioues, surtout lorsqu'elles sont dc faible épais-
seur. En effet lorsqu'on lait jaillir l'arc électrique entre l'ex-
trémité de la baguette de soudae et les bords en resard des deux
tôles à assembler, la flamme de l'arc électrique a tendance à briller
le metal, ce qui fait apparattre des trous. Ainsi, au lieu de dépo
ser du métal sur les deux bords en retard, les deux tales se trouvent détériorées sans autre pour autant assemblées.We know how difficult it is to weld two sheets side by side or
two metal walls, especially when they are thin
sister. Indeed, when milk spouts the electric arc between the ex-
end of the welding rod and the resard edges of the two
sheets to be assembled, the arc flame tends to shine
metal, which makes holes appear. So instead of depo
using metal on the two overdue edges, the two blades are deteriorated without further assembly.

La présente invention a pour but d'éviter ces inconvénients en proposant une baguette et un procédé nouveaux qui rendent plus Baci-
le, avec un meilleur résultat, l'opération d'assemblage de deux tales par soudage bord à bord.The object of the present invention is to avoid these drawbacks by proposing a new rod and method which make Baci-
the, with better result, the operation of assembling two blades by edge-to-edge welding.

On sait qu'une baguette de soudure de type connu a une forme cylindrique de révolution. Elle comprend une âme métallique cylindrique de révolution, entourée d'une gaine à section transversale éga- lement circulaire, généralement constituee par un fondant. It is known that a welding rod of known type has a cylindrical shape of revolution. It comprises a cylindrical metallic core of revolution, surrounded by a sheath of also circular cross section, generally constituted by a flux.

La présente invention concerne une baguette de sondage comportant elle aussi, une âme métallique cylindrique entourée d'une gaine de fondant, et elle est caractérisée, en ce que la section transver
sale de l'âme a une forme allongée. tandis que la section transver-
sale de la aine qui l'entoure a, elle aussi, une forme allongée.The present invention relates to a survey rod also comprising a cylindrical metallic core surrounded by a flux sheath, and it is characterized in that the cross-section
dirty of the soul has an elongated shape. while the cross-section
the groin around it also has an elongated shape.

Suivant une autre caractéristique de l'invention, l'âme metalli-
que a une section transversale rectangulaire ou elliptique, c'est-à-
dire que son petit diamètre est nettement plus court que son grand diamètre. Ia. gaine qui l'entoure a une section de même forme, définis-
sant un contour parallèle.According to another characteristic of the invention, the metallic core
that has a rectangular or elliptical cross section, that is
say that its small diameter is significantly shorter than its large diameter. Ia. sheath which surrounds it has a section of the same shape, defined
sant a parallel contour.

Suivant une autre caractéristique de l'invention, la baguette -ooms perte deux âmes métalliques a section circulaire juxtaposées, chacune
d'elles étant entourée d'une vaine de fondant a section sensiblement
en huit.iDans ces conditions, la baguette selon l'invention se pré-
sente sous une forme voisin de celle qu'auraient deux baguettes de
type connu juxtaposées.According to another characteristic of the invention, the baguette loses two metal cores with circular section juxtaposed, each
of them being surrounded by a stream of fondant having a substantially section
in eight. Under these conditions, the rod according to the invention pre-
feels in a form close to that which two sticks of
known type juxtaposed.

Le procédé selon l'invention pour effectuer la soudure o l'arc
de deux tôles placées bord à bord, consiste à utiliser une baguette
du type précité et il est caractérisé en ce que, pendant l'opéra- tion de soudage, on présente la baguette en l'orientant de façon que son plus rand diamètre soit sensiblement perpendiculaire à la direction des deux bords en regard, c'est-à-dire à la direction du déSlace- ment de la baguette lorsqu'on dc-pose le cordon de soudure.The method according to the invention for carrying out the welding or the arc
of two sheets placed edge to edge, consists in using a rod
of the aforementioned type and it is characterized in that, during the welding operation, the rod is presented while orienting it so that its longest diameter is substantially perpendicular to the direction of the two facing edges, this is that is, in the direction of movement of the rod when the weld bead is removed.

Suivant une autre caractéristique du procedé suivant l'invention, on dispose bord à bord les deux tales à assembler, en laissant entre elles l'intervalle libre d'une largeur supéreure au plus grand diamètre de la baguette selon 11 invention.  According to another characteristic of the process according to the invention, the two blades to be assembled are placed edge to edge, leaving between them the free space of a width greater than the largest diameter of the rod according to the invention.

Le dessin annexé, donne à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention. The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention.

- Figure 1 est une vue en perspective d'une baguette de soudage selon l'invention. - Figure 1 is a perspective view of a welding rod according to the invention.

- Figure 2 illustre le procédé selon l'invention pour le soudage bord à bord de deux tls.  - Figure 2 illustrates the method according to the invention for edge-to-edge welding of two tls.

- - Figure 3 est une vue en plan correspondante.- - Figure 3 is a corresponding plan view.

- Figure 4, figure 5, figure 6, figure 7 montrent quatre variantes possibles pour la forme de la section transversale d'une baguette selon l'invention. - Figure 4, Figure 5, Figure 6, Figure 7 show four possible variants for the shape of the cross section of a rod according to the invention.

On a représenté sur les dessins une baguette de soudage 1 destinée à être utilisée pour la soudure électrique. There is shown in the drawings a welding rod 1 intended to be used for electric welding.

La baguette illustrée sur les figures 1 à 4 comprend une ame mé- tallique 2 entouree d'une gaine de fondant 3. Suivant la caraetéris- tique de l'invention, la gaine Ayli-ndrique 2^a une section transversale rectangulaire très allongée tandis que la section transversale de la gaine 3 est approximativement celle d'un rectangle entourant le précédent. The rod illustrated in FIGS. 1 to 4 comprises a metallic core 2 surrounded by a fondant sheath 3. According to the characteristics of the invention, the Ayli-ndric sheath 2 has a very elongated rectangular cross section while that the cross section of the sheath 3 is approximately that of a rectangle surrounding the previous one.

La baguette 1 présente donc un grand diamètre 4 qui est nettement supérieur à son petit diamètre 5. The rod 1 therefore has a large diameter 4 which is clearly greater than its small diameter 5.

Le procédé de soudage selon l'invention (Figures2 et 3) est des tino à souder bord à bord deux tôles 6 et 7. Ce procédé consiste - d'une part à positionner avant soudage les deux tales 6 et 7 pour qu'entre leurs bords en regard, on laisse libre un intervalle dont la largeur 8 est supérieure à la longueur 4 du grand diamètre de la baguette 1 - d'autre part, pendant le soudage, on oriente la baguette 1 de façon que son grand diamètre 4 soit sensiblement perpendiculaire à la direction de la flèche 9 qui est à la fois la direction du mouvement de la baguette 1 et la direction des bords en regard sur les tôles 6 et 7.  The welding process according to the invention (Figures 2 and 3) is tino to weld edge to edge two sheets 6 and 7. This process consists - on the one hand of positioning before welding the two sheets 6 and 7 so that between their facing edges, an interval is left free whose width 8 is greater than the length 4 of the large diameter of the rod 1 - on the other hand, during welding, the rod 1 is oriented so that its large diameter 4 is substantially perpendicular to the direction of arrow 9 which is both the direction of movement of the rod 1 and the direction of the facing edges on the sheets 6 and 7.

Bien que la largeur 4 de la bai,otte soit inférieure à ment 8 des de bords en regard, on constate qu'en faisant jaillir l'arc électrique et en déplaçant l'extrémité de la baguette 1 dans le sens de la floche 9, on dépose Un cordon de soudure 10 qui assemble correctement les bords en regard des tôles 6 et 7, sans avoir tendance à percer ces dernières. Although the width 4 of the bay, otte is less than ment of the opposite edges, it can be seen that by causing the electric arc to burst and by moving the end of the rod 1 in the direction of the floche 9, a weld bead 10 is deposited which correctly assembles the facing edges of the sheets 6 and 7, without tending to pierce the latter.

On a représenté sur les figures 5 à 7 plusieurs autres variantes possibles pour la forme de la section transversale de la baguette 1. Several other possible variants have been shown in FIGS. 5 to 7 for the shape of the cross section of the rod 1.

:Dans la variante de la figure 5, la section transversale de 1' âme 2 est de forme ovale allongée, tandis que la gaine 3 définit une courbe ovale qui lui est parallèle. In the variant of FIG. 5, the cross section of the core 2 is of elongated oval shape, while the sheath 3 defines an oval curve which is parallel to it.

Dans le cas de la figure 6, l'âme de la baguette 1 est constituée par deux âmes métalliques cylindriques de révolution 11, noyées cate à c8te dans une même gaine de fondant 3 qui a un contour ovale ou plus ou moins en forme de huit. In the case of FIG. 6, the core of the rod 1 is constituted by two cylindrical metallic cores of revolution 11, embedded side by side in the same fondant sheath 3 which has an oval outline or more or less in the shape of an eight .

Enfin, la variante de la figure 7 montre une baguette 7 formée par simple juxtaposition de deux baguettes comportant chacune une âme cylindrique de révolution 11 entourée d'une gaine 3, également cynlindrique de révolution . Finally, the variant of FIG. 7 shows a rod 7 formed by simple juxtaposition of two rods each comprising a cylindrical core of revolution 11 surrounded by a sheath 3, also cylindrical of revolution.

Le principal avantage de l'invention est que, contrairement à toute attente, on constate que l'assemblage par soudage bord à bord de deux tôles se trouve grandement facilité, en supprimant les risques de fausse manoeuvre. The main advantage of the invention is that, contrary to all expectations, it is found that the assembly by edge-to-edge welding of two sheets is greatly facilitated, by eliminating the risks of false operation.

Un autre avantage est de permettre de recharger une tôle de faible épaisseur en y rapportant du métal. En particulier dans le cas des
Fig. 6 et 7, on constate que l'arc électrique s'allume alternativement sur l'une, puis sur l'autre des deux âmes 11 juxtaposes. Another advantage is to allow a thin sheet to be recharged by adding metal to it. Particularly in the case of
Fig. 6 and 7, we see that the electric arc ignites alternately on one, then on the other of the two cores 11 juxtaposed.
