Bakin Karfe Electrode

Ta yaya Bakin Karfe Electrodes suka bambanta da Carbon Karfe Electrodes?

Bakin karfe lantarki da carbon karfe electrodes an tsara su don walda nau'ikan kayan aiki daban-daban, kuma sun bambanta sosai a cikin abun da ke ciki, aikace-aikace, da kuma aiki. Bambanci na farko ya ta'allaka ne a cikin abun da suke ciki na gami. Bakin ƙarfe na lantarki ya ƙunshi babban matakan chromium (aƙalla 10.5%), tare da nickel, molybdenum, da sauran abubuwa, waɗanda ke ba da juriya da ƙarfi. Sabanin haka, na'urorin lantarki na carbon karfe da farko sun ƙunshi ƙarfe da carbon tare da ƙananan abubuwan haɗin gwiwa, wanda ya sa su dace da walƙiya na gaba ɗaya na ƙananan ƙarfe da ƙananan ƙarfe.
Bakin ƙarfe na lantarki an tsara shi musamman don aikace-aikace inda juriya na lalata da aikin zafi mai zafi ke da mahimmanci. Ana amfani da su a wuraren da aka fallasa ga danshi, sinadarai, da matsanancin zafi, kamar tsarin ruwa, tsire-tsire masu sinadarai, kayan abinci, da tsarin magunguna. A daya hannun, carbon karfe electrodes sun fi dacewa da tsarin walda, gyare-gyare, da aikace-aikace inda lalata juriya ba damuwa ba, kamar gini, gadoji, da ƙirƙira manyan injuna.
Wani bambanci shine halayen walda. Bakin ƙarfe na lantarki gabaɗaya yana samar da ƙarancin spatter, yana ba da kyakkyawan kawar da slag, da samar da beads masu tsafta idan aka kwatanta da na'urorin ƙarfe na carbon. Wannan yana da mahimmanci musamman ga aikace-aikacen da ke buƙatar tsaftataccen welds masu sha'awar gani. Koyaya, na'urorin lantarki na bakin karfe suna buƙatar kulawa da hankali don guje wa gurɓata da ƙarfe na carbon, saboda ƙazanta na iya yin illa ga juriyar lalata su.
Bugu da ƙari, na'urorin lantarki na bakin karfe galibi sun fi tsada fiye da na'urorin ƙarfe na carbon saboda abun ciki na gami, amma aikinsu a cikin aikace-aikace masu mahimmanci yana tabbatar da farashin. Carbon karfe electrodes, kamar E6010 ko E7018, sun fi araha da kuma m ga general-manufa waldi.

Wadanne Abubuwa Ya Kamata A Yi La'akari Da Su Lokacin Zabar Bakin Karfe Electrode?

Lokacin zabar na'urar lantarki ta bakin karfe, dole ne a yi la'akari da muhimman abubuwa da yawa don tabbatar da ingancin walda, ƙarfi, da juriya ga lalata. Na farko, yana da mahimmanci a daidaita wutar lantarki tare da nau'in ƙarfe na tushe. Bakin karfe an rarraba shi zuwa nau'o'i daban-daban, kamar 304, 308, 316, da 410, kuma kowanne yana buƙatar takamaiman lantarki. Misali, na'urorin lantarki kamar E308L-16 sun dace don walda bakin karfe 304, yayin da E316L-16 electrodes sun fi kyau don walda bakin karfe 316 saboda abun ciki na molybdenum, wanda ke haɓaka juriya a cikin mahalli masu arzikin chloride.
Yanayin aikace-aikacen wani muhimmin abin la'akari ne. Don welds da aka fallasa ga yanayi masu lalata sosai, kamar ruwan teku, acid, ko sinadarai, yakamata a zaɓi ƙananan na'urorin lantarki (misali, E316L) don hana hazo carbide da lalata intergranular. Don aikace-aikacen zafin jiki mai zafi, na'urorin lantarki waɗanda ke samar da iskar oxygen da juriya sun zama dole.
Hakanan dole ne a ɗauki matsayin walda. Yawancin na'urorin lantarki na bakin karfe, irin su E308L-16, duk nau'ikan lantarki ne, wanda ya sa su dace da lebur, a tsaye, sama, da walƙiya a kwance. Wannan yana tabbatar da sassauci a cikin ayyuka daban-daban da yanayin walda.
Daidaituwar tushen wutar lantarki yana da mahimmanci daidai. Na'urorin lantarki na bakin karfe yawanci suna dacewa da duka kayan wuta na AC da DC, amma yana da mahimmanci don tabbatar da takamaiman buƙatun na'urar da ake amfani da ita.
Sauran abubuwan sun haɗa da bayyanar walda, sauƙin cire slag, da matakan spatter. Don ayyukan da ke buƙatar tsaftataccen walda, masu santsi, na'urorin lantarki waɗanda ke samar da ƙarancin spatter da sauƙin cirewa an fi so. Bugu da ƙari, farashi na iya zama abin la'akari, kamar yadda na'urorin lantarki na bakin karfe sukan fi tsada fiye da na'urorin ƙarfe na carbon.
Ta hanyar yin la'akari da waɗannan abubuwan a hankali - kayan tushe, yanayin aikace-aikacen, matsayi na walda, tushen wutar lantarki, da halayen walda da ake so-welders na iya zaɓar mafi dacewa da na'urar lantarki ta bakin karfe don cimma ƙarfi, juriya, da ingancin welds.
