Fremgangsmåte til fremstilling av blank sveisetråd på jernbasis. Process for the production of iron-based bare welding wire.
Den foreliggende oppfinnelse går ut på The present invention is based on
en fremgangsmåte til fremstilling av blank a method for the production of blank
sveisetråd for automatisk lysbuesveising welding wire for automatic arc welding
under beskyttelsesglass som argon, helium, under protective glass such as argon, helium,

Ved anvendelse av blank sveisetråd for When using blank welding wire for

annet avsetning av sveiseperler på sveise-apparatets munnstykke og på arbeidstyk-ket. Fjernelse av de stivnede sveiseperler er other deposition of welding beads on the nozzle of the welding apparatus and on the workpiece. Removal of the solidified weld beads is
vanskelig og tidskrevende og utføres i al-minnelighet med verktøy som lett kan skade difficult and time-consuming and carried out in general with tools that can easily damage

For elektrisk lysbuesveising i automater For electric arc welding in automatic machines
under anvendelse av en beskyttelsesgass using a shielding gas
som inneholder mer enn 50 pst. karbondioksyd, er det kjent å anvende kjerneelektroder (Seelendråhte) hvis diameter ligger which contain more than 50 percent carbon dioxide, it is known to use core electrodes (Seelendråhte) whose diameter is
mellom 1,5 og 3 mm og hvis kjerne (Seele) between 1.5 and 3 mm and whose core (Seele)
består av silikater og titanater av alkali-metaller og oksyder, titanater og silikater consists of silicates and titanates of alkali metals and oxides, titanates and silicates
av jordalkalimetaller. I hvilken grad an-vendelsen av slike elektroder påvirker of alkaline earth metals. To what extent the use of such electrodes affects
sprutingen er ikke kjent, og forøvrig er the splashing is not known, and otherwise is
fremstillingen av slike kjerneelektroder be-tydelig vanskeligere og dertil kostbarere the production of such core electrodes significantly more difficult and moreover more expensive
enn fremstilling av blanke elektroder. than manufacturing blank electrodes.
Oppfinnelsen, som skaffer en frem- The invention, which provides a
gangsmåte til fremstilling av blanke sveise-elektroder som ikke oppviser de ovennevnte ulemper og særlig egner seg for lysbuesveising under beskyttelsesgass, består i at en tråd som er trukket nesten til sin endelige tykkelse og rengjort, og som fortrinnsvis er av vanlig sammensetning, forsynes med et fosfatskikt, f. eks. ved dypping i en kob-bervitriol oppløsning, hvoretter tråden trekkes til sin endelige dimensjon ved ytterligere lett trekking. procedure for the production of blank welding electrodes which do not exhibit the above-mentioned disadvantages and are particularly suitable for arc welding under shielding gas, consists in that a wire which has been drawn almost to its final thickness and cleaned, and which is preferably of a normal composition, is provided with a phosphate layer, e.g. by dipping in a copper-vitriol solution, after which the thread is drawn to its final dimension by further light pulling.
Ved fremgangsmåten ifølge oppfinnelsen er det lykkes å fremstille elektroder som egner seg ypperlig for alle sveiseoperasjoner hvor der vanligvis anvendes blanke tråder. Fosfatskiktet som ligger mellom kobberskiktet og den egentlige elektrode, gir en tilleggsbeskyttelse mot rustdannelse. Det har videre overraskende nok vist seg at antallet av sveiseperler blir ca. 50 pst. lavere når der anvendes en elektrode som er fremstillet i overensstemmelse med oppfinnelsen og er forsynt med et fosfatskikt. I tillegg er det fastslått at sveiseperlene på arbeidsstykket eller andre metalldeler lett kan fjernes, noe som heller ikke var å vente. Sveiseperlene, som forøvrig er mindre enn ved anvendelse av kjente elektroder, kan på enkel måte fjernes med en stålbørste, slik at skader på arbeidsstykket ved rengjørin-gen unngås og man oppnår en ikke ubety-delig arbeids- og tidsbespaz-else. With the method according to the invention, it has been possible to produce electrodes which are perfectly suitable for all welding operations where bare wires are usually used. The phosphate layer, which lies between the copper layer and the actual electrode, provides additional protection against rust formation. It has also surprisingly turned out that the number of welding beads is approx. 50 percent lower when an electrode is used which is manufactured in accordance with the invention and is provided with a phosphate layer. In addition, it has been established that the weld beads on the workpiece or other metal parts can be easily removed, which was also not expected. The welding beads, which are otherwise smaller than when using known electrodes, can be easily removed with a wire brush, so that damage to the workpiece during cleaning is avoided and a significant saving of work and time is achieved.
Ifølge et ytterligere trekk ved oppfinnelsen blir fosfatskiktet påført ved at tråden dyppes i en fosfatoppløsning. Det har vist seg hensiktsmessig å anvende en vandig oppløsning av tertiært sinkfosfat som fos-fatoppløsning. Likeledes oppnår man særlig gode resultater når man i henhold til et ytterligere trekk ved oppfinnelsen påfører kobberskiktet først etter at fosfatskiktet er tørket og utkrystallisert. Det har vist seg hensiktsmessig å nøytralisere fosfatskiktet, f. eks. med en boraxoppløsning, før kobberskiktet påføres. According to a further feature of the invention, the phosphate layer is applied by dipping the thread in a phosphate solution. It has proven appropriate to use an aqueous solution of tertiary zinc phosphate as a phosphate solution. Likewise, particularly good results are achieved when, according to a further feature of the invention, the copper layer is applied only after the phosphate layer has been dried and crystallized. It has proven appropriate to neutralize the phosphate layer, e.g. with a borax solution, before the copper layer is applied.
Fosfatskiktet påføres fortrinnsvis i en tykkelse av ca. 3 (.un. Ved at tråden trekkes til den ønskede dimensjon etter at fosfat-og kobberskiktet er påført, oppnår man at kobber- og fosfatskiktet bindes fast til hin-annen og ikke løsner ved transport eller under bruk i sveiseautomatene. The phosphate layer is preferably applied to a thickness of approx. 3 (.un. By pulling the wire to the desired dimension after the phosphate and copper layer has been applied, it is achieved that the copper and phosphate layer are firmly bonded to each other and do not loosen during transport or during use in the welding machines.
Ved fremgangsmåten ifølge oppfinnelsen anvendes der fortrinnsvis en tråd av kjent sammensetning, spesielt en tråd som foruten jern inneholder 0,05—0,20 pst. C, 0,05—3,0 pst. Mn og 0,10—3,0 pst. Si, samt eventuelt tilsetninger av ett eller flere av metallene titan, zirkonium og/eller aluminium i en mengde av opptil 1 pst. tilsammen og ett eller flere av metallene nikkel, krom, molybden og/eller kobber i en mengde av opptil 5 pst. av hvert. Utf ørelseseksempel: Ved sveising av arbeidsstykker av kje-leplate med karbondioksyd som beskyttelsesgass ble der først anvendt en blank sveiseelektrode av vanlig sammensetning. Deretter ble det samme arbeidsstykket sveiset med en ifølge den foreliggende oppfinnelse fremstillet sveiseelektrode som ved dypping var forsynt med et tynt sinkfosfatskikt og dessuten hadde et ytre kobberskikt. Ved fotografering av begge sveiseoperasjoner og telling av de på billedene viste sprute-linjer ble det fastslått at antallet av de ved spruting dannede sveiseperler ved anvendelse av en sveisetråd ifølge oppfinnelsen lå ca. 50 pst. lavere enn ved anvendelse av en vanlig sveisetråd. In the method according to the invention, a wire of known composition is preferably used, in particular a wire which, in addition to iron, contains 0.05-0.20% C, 0.05-3.0% Mn and 0.10-3.0% Say, as well as possibly additions of one or more of the metals titanium, zirconium and/or aluminum in an amount of up to 1 percent together and one or more of the metals nickel, chromium, molybdenum and/or copper in an amount of up to 5 percent .of each. Implementation example: When welding workpieces made of boiler plate with carbon dioxide as shielding gas, a blank welding electrode of ordinary composition was first used. Subsequently, the same workpiece was welded with a welding electrode manufactured according to the present invention which was provided with a thin zinc phosphate layer when dipped and also had an outer copper layer. By photographing both welding operations and counting the spray lines shown in the pictures, it was determined that the number of weld beads formed by spraying when using a welding wire according to the invention was approx. 50 percent lower than when using a normal welding wire.
