Description
10 15 20 25 30 35 8203586-6 f \ 2 pulvermängden/längdenheten är konstant. Den pulverfyllda rännan bockas sedan till ett slutet rör. Det fyllda rörets diameter reduceras därefter genom dragning till en för svetsändamålet lämplig diameter, som vanligtvis är mellan ca 1,2 och 3,2 mm. Vid denna dragning kan pulverfördel- ningen i röret inte längre kontrolleras. Uppkomsten av en viss ojämnhet av svetspulvrets fördelning i röret är oundviklig vid alla elektroder, vars diameter reduceras genom dragning. 10 15 20 25 30 35 8203586-6 f \ 2 the amount of powder / unit length is constant. The powder-filled the gutter is then bent into a closed pipe. The filled tube diameter is then reduced by drawing to a liner welding purpose suitable diameter, which is usually between about 1.2 and 3.2 mm. In this drawing, powder distribution can the connection in the pipe is no longer checked. The origin of a certain unevenness of the distribution of the welding powder in the tube is unavoidable at all electrodes, whose diameter is reduced by pulling.
Den föreliggande uppfinningen har till syfte att åstadkomma en fylld elektrod av det inledningsvis nämnda slaget, med vilken ett svetsgods av mycket jämn kvalitet kan erhållas.The present invention has for its object to provide a filled electrode of the kind mentioned in the introduction, with which a weld metal of very uniform quality can be obtained.
Enligt uppfinningen utmärker sig en elektrod därigenom, att höljet och pulverfyllningen innehåller samma metalliska beståndsdelar samt C och Si och förhållandet mellan de procentuella viktandelarna av varje metallisk beståndsdel i höljet relaterade till höljesvikten till de motsvarande procentuella viktandelarna av de metalliska bestånds- delarna i metallpulvret relaterade till vikten av metall- . pulvret inklusive C och Si är mellan 0,75 och l,33, före- trädesvis mellan 0,9 och l,l. Vid bestämningen av de metalliska beståndsdelarna beaktas inte de vanligen'före~ kommande föroreningarna.According to the invention, an electrode is thereby distinguished, that the casing and the powder filling contain the same metallic constituents as well as C and Si and the relationship between them percentage by weight of each metallic component in the casing related to the casing weight of the corresponding ones the percentages by weight of the metallic constituents the parts of the metal powder related to the weight of the metal . the powder including C and Si is between 0.75 and 1.33, preferably typically between 0.9 and 1.1. In determining the the metallic constituents are not considered the usual 'before ~ future pollutants.
Svetsgodsets kvalitet vad beträffar jämnhet är maximal när det sagda förhållandet är ca 1,0. Av praktiska och ekonomiska skäl är det dock mycket svårt att uppnå detta värde. Redan inom gränserna 0,75 och 1,33 erhåller man en mycket jämn svetskvalitet. Ligger förhållandet mellan 0,9 och l,l bör alla för närvarande kända krav på en jämn svetskvalitet kunna tillgodoses. Lämpligen svetsas elek- troden under skyddsgas.The quality of the weld metal in terms of evenness is maximum when the said ratio is about 1.0. Of practical and For financial reasons, however, it is very difficult to achieve this value. Already within the limits 0.75 and 1.33 you get a very even welding quality. Is the relationship between 0.9 and 1.1 should all currently known requirements for an even welding quality can be met. Suitably welded electrically the trout under shielding gas.
Den procentuella andelen av varje metallisk beståndsdel i höljet skall således inte avsevärt skilja sig från den motsvarande procentuella andelen i pulvret. Om höljet exv. innehåller a% Ni relaterat till höljesvikten skall 'il g.) 10 15 20 25 30 8203586-6 pulvret innehålla minst 0,75 a% Ni eller högst l,33 a% Ni, företrädesvis minst 0,9 a% Ni eller högst l,l a% Ni, relaterat till den pulvervikt som bestämmes av metall- pulvret samt C och Si.The percentage of each metallic component in the casing should therefore not differ significantly from it corresponding percentage of the powder. About the casing exv. contains a% Ni related to the casing weight shall 'il g.) 10 15 20 25 30 8203586-6 the powder contains at least 0.75 a% Ni or at most 1.33 a% Ni, preferably at least 0.9 a% Ni or at most 1.1 a% Ni, related to the powder weight determined by the metal the powder and C and Si.
Enligt en föredragen utföringsform av uppfinningen har den fyllda elektroden ett hölje, som innehåller utöver max 0,15% C och max 2,0% Si, som metalliska beståndsdelar i olegerad och/eller legerad form l7-26% Cr, 9-14% Ni, max 5% Mo, max 6% Mn och resten Fe, varvid procentsatserna är relaterade till höljesvikten och en pulverfyllning, som i den del, som utgöres av metalliska beståndsdelar samt C och Si innehåller utöver max 0,15% C och max 2,0% Si som metalliska beståndsdelar i olegerad och/eller legerad form 17-26% Cr, 9-14% Ni, max 5% Mo, max 6% Mn och resten Fe-pulver, varvid de sistnämnda procentsatserna är re- laterade till vikten av den del av pulverfyllning, Som är sammansatt av de nämnda beståndsdelarna.According to a preferred embodiment of the invention, it has filled electrode a housing, which contains in addition to max 0.15% C and max. 2.0% Si, as metallic constituents in unalloyed and / or alloyed form l7-26% Cr, 9-14% Ni, max 5% Mo, max 6% Mn and the remainder Fe, the percentages being related to the casing weight and a powder filling, as in the part consisting of metallic constituents and C and Si contains in addition to a maximum of 0.15% C and a maximum of 2.0% Si as metallic constituents of unalloyed and / or alloyed form 17-26% Cr, 9-14% Ni, max 5% Mo, max 6% Mn and the rest Fe powder, the latter percentages being re- later to the weight of the part of the powder filling, which is composed of the said constituents.
Enligt uppfinningen är det fördelaktigt att pulverfyll- ningen innehåller slaggbildare och/eller bâgstabilisatorer, som totalt utgör högst 20% av pulverfyllningens totalvikt.According to the invention, it is advantageous that powder filling contains slag formers and / or arc stabilizers, which in total does not exceed 20% of the total weight of the powder filling.
Som slaggbildare används exv. Al203, Si02, som båg- stabilisatorer, exv. CaF2, CaC03.As slag formers are used e.g. Al 2 O 3, SiO 2, as arc- stabilizers, e.g. CaF2, CaCO3.
Det är vidare fördelaktigt att förhållandet mellan höljes- vikten och den totala pulvervikten är mellan 0,9 och 2,0, företrädesvis mellan 1,2 och 1,7. Är förhållandet mindre än 0,9 blir höljet för tunt och är det större än 2,0 blir höljet för tjockt. värden uppstår betydande problem vid tillverkning av Vid förhållandet utanför dessa gräns- tråden, särskilt vid dragningen till den erforderliga diametern.It is further advantageous that the relationship between the weight and the total powder weight is between 0.9 and 2.0, preferably between 1.2 and 1.7. Is the ratio smaller than 0.9, the casing becomes too thin and if it is larger, 2.0 becomes the casing is too thick. significant problems arise in the manufacture of In the case of relations outside these the wire, especially when pulling to the required one diameter.
