Description
Foreliggende oppfinnelse angår en sveiseelektrode for sveising av støpejern. Spesielt angår oppfinnelsen en sveiseelektrode for høyspenningsbuesveising omfattende en kjernetråd av en nikkel-jernlegering og utstyrt med et metallbelegg og videre omfattende et flussmiddel. The present invention relates to a welding electrode for welding cast iron. In particular, the invention relates to a welding electrode for high-voltage arc welding comprising a core wire of a nickel-iron alloy and equipped with a metal coating and further comprising a flux.
Denne elektrode kan benyttes med vekselstrøm eller This electrode can be used with alternating current or
likestrøm uten overoppheting.direct current without overheating.
Hittil er det kjent at elektroder med en jernholdig legeringskjerne til sveising av støpejern blir meget varm ved sveiseavsetning. Disse elektroder ifølge teknikkens stand blir noen ganger så varme at elektrodebelegget brytes ned etter at 2/3 av elektroden er forbrukt, slik at den gjenværende elektrode gjøres ubrukbar og må kasseres. Dessuten er disse elektroder ifølge teknikkens stand ømfintlige overfor behandling på grunn av følsomhet for alvorlig overoppheting. Disse mangler er betydelige da støpejernselektroder med nikkel-jernkjerne gir mange vesentlige fordeler ved sveising av støpejern, og da de hyppig benyttes til dette formål. Until now, it has been known that electrodes with a ferrous alloy core for welding cast iron become very hot during welding deposition. According to the state of the art, these electrodes sometimes become so hot that the electrode coating breaks down after 2/3 of the electrode has been consumed, so that the remaining electrode is rendered unusable and must be discarded. Moreover, these prior art electrodes are sensitive to treatment due to susceptibility to severe overheating. These shortcomings are significant as cast iron electrodes with a nickel-iron core offer many significant advantages when welding cast iron, and as they are frequently used for this purpose.
Hensikten med foreliggende oppfinnelse er å tilveie-bringe en elektrode for høyspenningsbuesveising som ikke opp-viser de til nå foreliggende mangler, og oppfinnelsen angår således en sveiseelektrode for høyspenningsbuesveising omfattende en kjernetråd av en nikkel-jernlegering med sterkt redusert overhetirig under sveising, der kjernétråden har et metallbelegg valgt blant kobber, sølv og legeringer derav, og denne sveiseelektrode karakteriseres ved at metallbelegget igjen er belagt med et sveiseflussmiddel med en sammensetning i vekt-% på opptil 25% nikkelpulver, 4-18% nikkelbelagt magnesiumpulver, 18- The purpose of the present invention is to provide an electrode for high-voltage arc welding which does not exhibit the hitherto existing defects, and the invention thus relates to a welding electrode for high-voltage arc welding comprising a core wire of a nickel-iron alloy with greatly reduced superheating during welding, where the core wire has a metal coating chosen from among copper, silver and alloys thereof, and this welding electrode is characterized by the fact that the metal coating is again coated with a welding flux with a composition in % by weight of up to 25% nickel powder, 4-18% nickel-coated magnesium powder, 18-
47% av et jordalkalimetallkarbonat, 5-18% av et antioksydasjonsmiddel, opptil 11% jernpulver, 2-13% kobberpulver, 7-11% kalsium- 47% of an alkaline earth metal carbonate, 5-18% of an antioxidant, up to 11% iron powder, 2-13% copper powder, 7-11% calcium-
fluorid, 4-24% karbonstoffer, 1-6% leire, hvilket sveiseflussmiddel er blandet med natrium- eller kaliumsilikatbindemiddel i en mengde fra 40-50% av det totale flussmidddelbelegg, hvilket sveiseflussmiddel utgjør fra 18-52% av den totale elektrodevekt. fluoride, 4-24% carbon substances, 1-6% clay, which welding flux is mixed with sodium or potassium silicate binder in an amount from 40-50% of the total flux coating, which welding flux constitutes from 18-52% of the total electrode weight.
I den senere tid er det prøvet å komme frem til en virkelig overlegen sveiseelektrode for sveising av "støpejern. Av spesiell viktighet var ønsket om å frembringe en elektrode av nikkel-jerntypen til bruk på støpejern, som ikke ble alvorlig overopphetet ved sveiseavsetning. In recent times, attempts have been made to arrive at a truly superior welding electrode for welding "cast iron. Of particular importance was the desire to produce an electrode of the nickel-iron type for use on cast iron, which was not seriously overheated by welding deposition.
Etter utstrakt forskning ble det oppdaget at elektroder ifølge oppfinnelsen med nikkel-jernkjerner, men på overflaten omgitt av et tynt sjikt av en legering med høy ledningsevne, slik som kobber-og sølvlegeringer, ga betraktelig redusert overoppheting. "Nikkel-jern", slik det heri benyttes, betyr legeringer som inneholder jern og nikkel, slik at nikkelinnholdet er mellom 40 og 65 vekt-%. After extensive research, it was discovered that electrodes according to the invention with nickel-iron cores, but on the surface surrounded by a thin layer of an alloy with high conductivity, such as copper and silver alloys, gave considerably reduced overheating. "Nickel-iron", as used herein, means alloys containing iron and nickel, such that the nickel content is between 40 and 65% by weight.
Ved fortsatte undersøkelser ble det funnet at tykkelsen av det ledende ytre sjikt av sølv-eller kobberlegering, anbrakt på den ytre sylindriske overflate av kjernetråden som ga de beste resultater ifølge oppfinnelsen, kunne defineres innen et område som kan bestemmes på følgende måte: On further investigation, it was found that the thickness of the conductive outer layer of silver or copper alloy, placed on the outer cylindrical surface of the core wire which gave the best results according to the invention, could be defined within a range which can be determined in the following way:
Minimal tykkelse av det ledende sjiktMinimal thickness of the conductive layer
i mm = 0,013 . (diameteren av kjerne-in mm = 0.013 . (the diameter of the core
tråden i mm)thread in mm)
Maksimal tykkelse av det ledende sjiktMaximum thickness of the conductive layer
i mm = 0,019 . (diameteren av kjerne-in mm = 0.019 . (the diameter of the core
tråden i mm) .the thread in mm).
For fagmannen, vil det være tydelig at ledende sjikt av rent kobber eller rent sølv gir optimale resultater, men også at sølv legert med andre elementer og kobber legert med andre elementer, vil gi akseptable resultater der den termiske ledningsevne i den resulterende legering ikke drastisk påvirkes. For the person skilled in the art, it will be clear that conductive layers of pure copper or pure silver give optimal results, but also that silver alloyed with other elements and copper alloyed with other elements will give acceptable results where the thermal conductivity of the resulting alloy is not drastically affected .
En typisk sveiselektrode av denne type består av A typical welding electrode of this type consists of
følgende elementer:the following items:
En kjernestav av en legering av nikkel og jern med hovedsakelig 58-60 vekt-% nikkel. Hele den ytre sylindriske overflate av kjernen er utstyrt med et sjikt av kobber. Hvis det antas at kjernen har en diameter på 3,17 mm, må tykkelsen av overflatekobbersjiktet på grunnlag av de forannevnte matemat- iske ligninger, ligge innen området 0,043 mm til 0,061 mm. Kobbersjiktet kan anlegges på kjerneoverflaten ved hjelp av flere forskjellige fremgangsmåter, velkjente i teknikkens stand, slik som elektrolyse eller påsprøyting. A core rod of an alloy of nickel and iron with mainly 58-60% nickel by weight. The entire outer cylindrical surface of the core is equipped with a layer of copper. If it is assumed that the core has a diameter of 3.17 mm, the thickness of the surface copper layer on the basis of the aforementioned mathe- ical equations, lie within the range 0.043 mm to 0.061 mm. The copper layer can be applied to the core surface using several different methods, well known in the art, such as electrolysis or spraying.
Ifølge oppfinnelsen er et flussbelegg fordelt på kjernen av elektrodene. Mengden av flussbelegget i vekt-% "av elektroden ifølge oppfinnelsen, sammenlignet med den totale vekt av elektroden er som følger: According to the invention, a flux coating is distributed on the core of the electrodes. The amount of the flux coating in % by weight of the electrode according to the invention, compared to the total weight of the electrode is as follows:
Eksempler på brede og foretrukne områder av flussbelegget ifølge oppfinnelsen er som følger, uttrykt i vekt-%: Examples of wide and preferred areas of the flux coating according to the invention are as follows, expressed in % by weight:
Som vel kjent, i teknikkens stand, er flussbelegget utstyrt med et egnet bindemiddel slik som natriumsilikat eller kaliumsilikat for å understøtte adhesjonen til elektrodekjernen. Bindemidlet blandes med flussmidlet i meng'der tilsvarende 40-50 vekt-% bindemiddel, beregnet på det totale flussbelegg. As is well known, in the state of the art, the flux coating is provided with a suitable binder such as sodium silicate or potassium silicate to support adhesion to the electrode core. The binder is mixed with the flux in amounts corresponding to 40-50% by weight binder, calculated on the total flux coating.
Ved sveiseavsetning ble det funnet at elektrodeneDuring welding deposition it was found that the electrodes
ifølge oppfinnelsen avsatte sveiseavsetninger med nodulær grafitt. Dette er bemerkelsesverdig da nærværet av den nodulære grafitt i sveiseavsetningene ikke bare gir en struktur som er according to the invention deposited welding deposits with nodular graphite. This is remarkable as the presence of the nodular graphite in the weld deposits not only gives a structure which is
høyst ønskelig ved støpejern, men denne struktur indikerer også maksimal duktilitet i sveisemetallavsetningen.. Elektrodene ifølge oppfinnelsen har også ekstremt gode sveisbarhetsegenskaper ved stillings- og ut-av-stilling-sveising. Videre gir disse elektroder ved sveising en myk sveisebue og en jevn elektrode-avbrenning, og de senker seg ikke inn i støpejernsbasismetallet ved sveiseavsetning, og således fremkommer minimal basismetall-gjennomtrengning og fortynning, noe som vanligvis er større problemer ved sveising av støpejern. Videre ga elektrodesveise-avsetningene spesielt god slaggdekning, med solide og estetisk godt utseende sveiseavsetninger. highly desirable for cast iron, but this structure also indicates maximum ductility in the weld metal deposit. The electrodes according to the invention also have extremely good weldability properties for positioning and out-of-position welding. Furthermore, when welding, these electrodes provide a soft welding arc and an even electrode burn, and they do not sink into the cast iron base metal during welding deposition, thus resulting in minimal base metal penetration and dilution, which are usually greater problems when welding cast iron. Furthermore, the electrode welding deposits provided particularly good slag coverage, with solid and aesthetically good-looking welding deposits.
Som nevnt ovenfor gir. flussmidlet ifølge oppfinnelsen sammen med sveisestaven en meget god skjøt som inneholder nodulær grafitt. Dette fordi flussmidlet inneholder nikkelbelagt magnesium som er et noduleringsmiddel for grafitt. As mentioned above provides. the flux according to the invention together with the welding rod a very good joint containing nodular graphite. This is because the flux contains nickel-coated magnesium, which is a nodulating agent for graphite.
Videre er karboninnholdet i flussmidlet relativt høyt, 4-20 vekt-%, noe som understøtter en fluid sveiseavsetning. For imidlertid å unngå dannelse av grafittflak i sveiseavsetningen, noe som svekker sveisesømmen, er magnesium inkludert i flussmidlet for effektivt å nodulere grafitten. Furthermore, the carbon content in the flux is relatively high, 4-20% by weight, which supports a fluid welding deposit. However, to avoid the formation of graphite flakes in the weld deposit, which weakens the weld seam, magnesium is included in the flux to effectively nodulate the graphite.
Magnesiumpartiklene er nikkelbelagt for å beskytte magnesium fra å oksydere ut under sveisingen, slik at det effektivt kan oppnås en grafittisk nodulær struktur i sveisesømmen. I tillegg inneholder også flussmidlet desoksyderingsmidler som beskytter magnesium. The magnesium particles are nickel-coated to protect magnesium from oxidizing during welding, so that a graphitic nodular structure can be effectively achieved in the weld seam. In addition, the flux also contains deoxidizers that protect magnesium.
De andre bestanddeler som angis ovenfor i flussmidlet, dvs. alkalimetallkarbonat, kalsiumfluorid, leire osv., virker også som beskyttende dekke for å muliggjøre at de ønskede reak-sjoner foregår i sveisen. For eksempel sikrer flussmidlet kobberopptak i sveiseavsetningen og øker i tillegg sveiseleger-ingens fluiditet. The other components listed above in the flux, i.e. alkali metal carbonate, calcium fluoride, clay, etc., also act as a protective cover to enable the desired reactions to take place in the weld. For example, the flux ensures copper absorption in the welding deposit and also increases the fluidity of the welding alloy.
Flussmidlet ifølge oppfinnelsen gir således tallrike fordeler både med henblikk på å regulere de metallurgiske reak-sjoner i den smeltede sveiseavsetning for å danne en nodulær struktur som er meget duktil, samt med henblikk på en glattfjevn avsetning. The flux according to the invention thus offers numerous advantages both with a view to regulating the metallurgical reactions in the molten welding deposit to form a nodular structure which is very ductile, as well as with a view to a smooth and smooth deposit.
Av spesiell viktighet er den fordel at elektrode ifølge oppfinnelsen kan benyttes med bruk av både vekselstrøm og like-strøm. Ved sveiseavsetning arbeider således elektrodene betraktelig kaldere enn elektroder til sveising av støpejern ifølge teknikkens stand. Elektrodene ifølge oppfinnelsen kan utnyttes 100% uten medfølgende overopphetingsproblemer.. Of particular importance is the advantage that the electrode according to the invention can be used with the use of both alternating current and direct current. During welding deposition, the electrodes thus work considerably colder than electrodes for welding cast iron according to the state of the art. The electrodes according to the invention can be used 100% without accompanying overheating problems.
