PERFECTIONNEMENTS AUX ELECTRODES POUR LA SOUDURE.
La présente invention se rapporte à la soudure de l'aluminium et plus spécialement aux électrodes de soudure convenant pour la soudure à 1-lare de 1-'aluminium.
Le but essentiel de l'invention est de fournir une nouvelle électrode qui puisse être utilisée avec succès pour souder l'aluminium par des soudeurs d'habileté moyenne.
Parmi les avantages de la nouvelle baguette de soudure on peut citer
1) Absence de projections pendant l'opération de soudure;
2) Plus grande fluidité du métal d'apport pendant la soudure;
3) Plus forte densité du dépôt et
4) Résistance à la traction fortement accrue de la soudure obtenue comparée à celle qu'on peut former avec les électrodes connueso
D'autres buts et avantages ressortiront de la suite de la descriptiono
La nouvelle électrode est avantageusement une électrode enrobée dont l'âme contient essentiellement de 1-'aluminium mais également ..ne forte proportion de silicium, à savoir de 7 à 15% en poids environ. L'âme comprend donc de 85 à 93 % d9aluminium et de 7 à 15 % de silicium.
Elle peut également contenir de petites quantités d'autre métaux comme le cuivre, le titane, le chrome, le zinc, le magnésium, le fer et le nickelo
L'enrobage de fondant contient un ou plusieurs fluorures et un ou plusieurs chlorures, la partie fluorure étant constituée par le fluorure
<Desc/Clms Page number 2>
d'un ou plusieurs des métaux du groupe formé par le sodium, le lithium, le potassium, le baryum, le calcium, le zinc, l'étain et le cadmium, et la partie chlorure étant constituée par le chlorure d'un ou de plusieurs métaux du même groupe.
Il importe que l'enrobage ne comporte pas moins de 15 % de fluorure et pas moins de 55 % de chlorure; les gammes sont donc 15 à 45 % Poix' le fluorure et 55 à 85 % pour le chlorure.
Un exemple typique d'une composition de baguette donnant des résultats très satisfaisants est :aluminium 85 %, silicium 15 %, enrobée d'un fondant contenant : fluorure 30 %, chlorure 70 %.
Lorsque la nouvelle électrode enrobée est placée dans un porte- électrode connu, la soudure de l'aluminium est grandement simplifiée, et en fait aussi exempte de difficultés que la soudure de l'acier doux.
Les projections coûteuses qui sont une caractéristique habituelle de la soudure de l'aluminium avec les électrodes connues dïsparaissent entièrement La fluidité du métal de soudure est fortement accrue.
Le dépôt de soudure est particulièrement dense et a une résistance à la traction beaucoup plus élevée, celle-ci étant de l'ordre de 8000 livres par pouce carré (560 kg/cm2) de plus que celle qu'on peut obtenir avec les électrodes connues. En plus d'une excellente liaison, on obtient un bon mariage de couleurs et une résistance satisfaisante à la corrosion.
Les allusions aux électrodes connues désignent ici les électrodes formées d'une âme en aluminium pur ou en aluminium à faible teneur en silicium ne dépassant pas par exemple 5 %.
La description ci-dessus se rapporte aux meilleures formes de réalisation de l'invention. Gelle-ci n'est toutefois pas limitée à ces formes de réalisation.

WELDING ELECTRODES IMPROVEMENTS.
The present invention relates to the welding of aluminum and more especially to welding electrodes suitable for 1-lare welding of 1-aluminum.
The essential object of the invention is to provide a novel electrode which can be used successfully to weld aluminum by welders of average skill.
Among the advantages of the new welding rod we can mention
1) Absence of projections during the welding operation;
2) Greater fluidity of the filler metal during welding;
3) Higher density of the deposit and
4) Strongly increased tensile strength of the weld obtained compared to that which can be formed with known electrodes
Other objects and advantages will emerge from the remainder of the description.
The new electrode is advantageously a coated electrode, the core of which contains essentially 1-aluminum but also ..ne high proportion of silicon, namely from 7 to 15% by weight approximately. The core therefore comprises 85 to 93% aluminum and 7 to 15% silicon.
It may also contain small amounts of other metals such as copper, titanium, chromium, zinc, magnesium, iron and nickelo
The flux coating contains one or more fluorides and one or more chlorides, the fluoride part consisting of fluoride
<Desc / Clms Page number 2>
one or more of the metals of the group formed by sodium, lithium, potassium, barium, calcium, zinc, tin and cadmium, and the chloride part being constituted by the chloride of one or more several metals of the same group.
It is important that the coating contains not less than 15% fluoride and not less than 55% chloride; the ranges are therefore 15 to 45% Pitch for fluoride and 55 to 85% for chloride.
A typical example of a rod composition giving very satisfactory results is: aluminum 85%, silicon 15%, coated with a flux containing: fluoride 30%, chloride 70%.
When the new coated electrode is placed in a known electrode holder, the welding of aluminum is greatly simplified, and in fact as easy as the welding of mild steel.
The expensive spatter which is a usual feature of welding aluminum with known electrodes completely disappears. The fluidity of the weld metal is greatly increased.
The weld deposit is particularly dense and has a much higher tensile strength, this being in the order of 8000 pounds per square inch (560 kg / cm2) more than that which can be obtained with the electrodes. known. In addition to an excellent bond, a good color combination and satisfactory corrosion resistance are obtained.
Allusions to known electrodes here designate electrodes formed from a core of pure aluminum or of aluminum with a low silicon content not exceeding, for example, 5%.
The above description relates to the best embodiments of the invention. However, this is not limited to these embodiments.
