Dekket elektrode for lysbuesveising av aluminium og dets legeringer. Covered electrode for arc welding of aluminum and its alloys.

aluminiumlegeringer, benytter man vanligvis disse elektroder i forbindelse med aluminum alloys, these electrodes are usually used in connection with
et flussmdddel som er istand til å oppløse a flux that is capable of dissolving
det aluminiumoksyd som dannes under the aluminum oxide that forms below
sveisingen. Flussmidler har også til opp-gave å stabilisere og ionisere lysbuen og the welding. Fluxes also have the task of stabilizing and ionizing the arc and

Disse blandinger er vanligvis temmelig utpreget hygroskopiske, slik at når man anvender dem i or powdered mixtures of chlorine compounds and fluorine compounds of alkali and/or alkaline earth metals. These mixtures are usually quite distinctly hygroscopic, so that when you use them in

Fra norsk patent nr. 84 571 er således From Norwegian patent no. 84 571 is thus
kjent en buesveisingselektrode med en known an arc welding electrode with a
kjerne av aluminium eller annet lettmetall core of aluminum or other light metal
og med en mantel som i det vesentligste and with a mantle as the most essential
består av kalium-aluminiumflorid, idet der consists of potassium aluminum fluoride, as there
likeledes kan foreligge små mengder av there may also be small amounts of
litiumkloiid og kaliumklorid, f. eks. i forholdet 13,4 deler Al-fluorhydrat, 9,2 deler lithium chloride and potassium chloride, e.g. in the ratio 13.4 parts Al-fluorohydrate, 9.2 parts
kaliumfluorid og 6 deler litiumklorid. potassium fluoride and 6 parts lithium chloride.
Av stor betydning er også forholdet The relationship is also of great importance

feilfri ionisering av lysbuen, en god slagg-strøm og tilfredsstillende slaggfjernelse. flawless ionization of the arc, a good slag flow and satisfactory slag removal.
Formålet med foreliggende oppfinnelse er å eliminere de nevnte mangler, sikre en førsteklasses sveiseoperasjon og god slagg-fordeling, samtidig som egenskapene for en sveisesøm forbedres med hensyn til glans og tetthet. Oppfinnelsen tar således sikte på å skaffe en dekket elektrode for lysbuesveising av aluminium og dets legeringer, bestående av en kjerne av aluminium og/eller aluminiumlegering og en mantel dannet helt eller delvis av en blanding av halogenider av alkali- og eller jordalkalimetaller, idet en del av de i mantelen foreliggende halogenider foreligger i form av K3AlFfi, og oppfinnelsen utmerker seg ved at mantelen inneholder 17—23 pst. fluorloner, 25—40 pst. klorioner, 2—7 pst. aluminiumioner, og resten som alkali- og/ eller jordalkaliioner. og at 18—20 pst. av materialene i mantelen foreligger i form av K3A1F(1. The purpose of the present invention is to eliminate the aforementioned shortcomings, ensure a first-class welding operation and good slag distribution, while at the same time improving the properties of a weld seam with regard to gloss and tightness. The invention thus aims to provide a covered electrode for arc welding of aluminum and its alloys, consisting of a core of aluminum and/or aluminum alloy and a mantle formed wholly or partly from a mixture of halides of alkali and or alkaline earth metals, being a part of the halides present in the mantle are in the form of K3AlFfi, and the invention is distinguished by the fact that the mantle contains 17-23 percent fluorine ions, 25-40 percent chlorine ions, 2-7 percent aluminum ions, and the rest as alkali and/or alkaline earth ions . and that 18-20 per cent of the materials in the mantle are in the form of K3A1F (1.
Mantelen kan fortrinnsvis inneholde: The mantle can preferably contain:
minst 40 pst. halogenid-ioner, at least 40 percent halide ions,
minst 20 pst. alkali- eller jordalkaliioner og at least 20 percent alkali or alkaline earth ions and
minst 3 pst. aluminium-ioner. at least 3 percent aluminum ions.
Det er særlig fordelaktig at mantelen inneholder: It is particularly advantageous that the mantle contains:
minst 15 pst. fluor-ioner, at least 15 percent fluoride ions,
minst 12 pst. kalium-ioner og minst 2 pst. aluminium-ioner. at least 12 percent potassium ions and at least 2 percent aluminum ions.
En liten del av K., Al F(1 kan være erstattet av kryolitt (Na Ål Fc). A small part of K., Al F(1) may be replaced by cryolite (Na Ål Fc).
De således dekkede elektroder er lite hygroskopiske og forholdsvis stabile. De gir en sveisesøm som er tett og blank, praktisk talt fri for porøsitet, samt har de meget gode egenskaper at den er seig og elastisk. Dertil kommer at elektrodene ifølge oppfinnelsen også kan være spesielt behandlet mot den korroderende virkning som visse bestanddeler i mantelen kan ha på den metalliske elektrodekjerne. Til dette formål kan man i mantelen innleire stoffer som hindrer korrosjon, særlig kromater, eller også på forhånd behandle den metalliske kjerne ved neddykking i et bad inne-holdende særlig salpetersyre eller kromat-ioner. The electrodes covered in this way are not hygroscopic and relatively stable. They provide a weld seam that is tight and shiny, practically free of porosity, and they also have the very good properties of being tough and elastic. In addition, the electrodes according to the invention can also be specially treated against the corrosive effect that certain components in the mantle can have on the metallic electrode core. For this purpose, substances that prevent corrosion, especially chromates, can be embedded in the mantle, or the metallic core can also be pre-treated by immersion in a bath containing, in particular, nitric acid or chromate ions.
Denne fremgangsmåte for beskyttelse av aluminium og aluminiumlegeringer mot korrosjon er i og for seg kjent. This method for protecting aluminum and aluminum alloys against corrosion is known per se.
