Iyo electrode iwaya yakavharidzirwa yesimbi uye inofanirwa kugadzirwa kubva kune chinhu chakafanana mumidziyo uye kuumbwa kune simbi iri kushiswa, uye pane zvakati wandei zvinopinda mukusarudza iyo electrode chaiyo yepurojekiti yako.
Nepo shielded metal arc welding (SMAW) kana "stick" maelectrodes anobatika uye ave chikamu cheweld, mamwe maelectrode (seaya anoshandiswa paTIG welding) haabatike, zvichireva kuti haanyungudike uye kuva chikamu cheweld. musono. Kuparadzaniswa kwemusono, mumatambudziko aya, kushandiswa kwe electrode kunodiwa.
Isu paEng-weld tinoziva kuti kusarudza electrode chaiyo kwakakosha pakusimba kweweld, weld quality, spatter minimization uye kuchenesa.
Cellulose maelectrodes maelectrode ewelding akaputirwa nesheath ine organic zvinhu. Kazhinji inenge 30% nehuremu hwejasi ndeye cellulose, asi kune dzimwe nzvimbo dzenyika cellulose nehupfu hwehuni zvinogona kuwedzerwa pakuputira kuderedza iyo yakachena cellulose.
Izvo zvakasiyana-siyana zvinokonzerwa nemagetsi mumagetsi emagetsi zvichaora mu arc kuti iite carbon dioxide, carbon monoxide uye hydrogen, iyo yose inowedzera magetsi mukati me arc, zvichiita kuti arc yakasimba uye yakaoma. Saka, maelectrodes ecellulose anogona kupinda kusvika 70% kudzika kupfuura maelectrodes anowirirana ane mwero wazvino uno.
Kazhinji inogadzirwa nemucheka mutete kana wepakati, kunyange izvi zvinogadzira slag inogona kubviswa mushure mekugadzirisa kwekugadzirisa, izvi zvinogona kukonzera kurasikirwa kukuru kwe spatter. Nekudaro, iyo yakatwasuka pasi welding kugona uye kugona kwekupinda kweiyi electrode kwakanaka kwazvo nekuda kwegap rekuzadza mukuputira.
Iyo low hydrogen electrode igasi shielded arc welding (SMAW) inogona kudyiwa nemvura isingasviki 0.6% kana ichienzaniswa neyekare 4-6% yemvura ine cellulosic electrodes.
Kazhinji, low hydrogen electrode seE7018 rod electrode inopa vashandisi yakaderera spatter uye yakatsetseka, yakagadzikana uye yakanyarara arc. Izvi zvinhu zvinoita kuti maelectrode aya ave sarudzo yakanaka kune vese vane ruzivo welders uye vanotanga. Izvo zvimiro zveaya mafiller simbi maelectrode anopa welder yakanaka arc control uye kuderedza kudiwa kwe post-weld kuchenesa.
Kusiyana nemamwe maelectrode akadai seE6010 kana E6011, low hydrogen electrode inopa yepamusoro deposition uye kupinza mitengo, zvichibvumira welder kuwedzera mamwe simbi kujoinhi chero nguva, kuvandudza weld simba uye kudzivirira welding kuremara sekushaiwa kwekupinda.
Kazhinji, maelectrode esimbi akapfava anopa arc yakanyarara uye yakagadzikana ine yakaderera kupinda, ichiita kuti ive yakakodzera kune yakafara gap bridging uye matete mapeji kunyorera. Zvisinei, kune marudzi akasiyana-siyana emagetsi esimbi akapfava, imwe neimwe iine zvimiro zvakasiyana zvishoma uye nekudaro inokodzera zvirinani kune akasiyana maapplication.
Semuyenzaniso, giredhi 6013 ibasa rakajairwa rakapfava simbi electrode inopa yakadzika kupinda uku uchichengeta yakatsetseka uye yakagadzikana arc. Iyo arc iri nyore kugadzira patsva, iyo welding seam yakanaka, iyo spatter ishoma, iyo slag iri nyore kudzora, yakakodzera vertical down welding.
Iyo 7018 arc electrode, kune rumwe rutivi, isimbi yakapfava electrode yakagadzirirwa welding yakakwirira-simba kabhoni simbi zvinhu. Iri electrode rinowanzo shandiswa pakugadzira welding nekuda kweiyo weld's crack resistance. Asi izvi zvinogadzira yakawanda slag, iyo isina kukodzera vertical down welding.
Elekitirodhi yesimbi yekupedzisira yatichaona ndeye 6011. Iyi electrode yakadzama yekupinda yakadzika inopa arc yakatsetseka uye yakatsiga kana welding galvanized nyoro simbi uye mamwe mashoma alloy simbi. Kupfeka kwaro kunogadzira arc ine simba yekupinda kwakadzika, uye slag layer yakatetepa uye iri nyore kubvisa.
Kufanana nemamwe maelectrode ataona pamusoro apa, maelectrode esimbi asina tsvina anouya mumhando dzakasiyana-siyana, rimwe nerimwe rakasiyana zvishoma nerekare.
Pano tinotarisa magiredhi matatu akasiyana emagetsi esimbi asina tsvina, 308, 309 uye 316, uye nguva yekuashandisa.
Kana uri kushandisa magiredhi 301, 302, 304, 305 uye kukanda alloys CF-3 neCF8, saka tinokurudzira kuti ushandise 308L, kusanganisira ER308LSi electrodes. Aya maelectrode esimbi asina tsvina akanakira austenitic simbi isina tsvina, asi kune maapplication akadai sekugadzira magetsi, isu tinokurudzira iyo 308H electrode sezvo iyi yakakwira kabhoni electrode ichipa zvirinani zvinokambaira pakupisa kwakanyanya.
Pakujoinha simbi yakapfava kana mild simbi alloys kune simbi isina tsvina, shandisa 309L, kusanganisira ER309LSi. Izvi zvinoshandawo pakujoinha simbi dzisina tsvina dzakadai se409 kana 304L simbi isina tsvina. Pamusoro peizvi, ivo vanofanirwawo kushandiswa kubatanidza 309 base masimbi.
Paunenge uchishandisa base simbi 316L uye 316 uye akakandwa akaenzana CF-8m uye CF-3M, chete 316L ndiyo inofanirwa kushandiswa seyekuzadza simbi, kusanganisira ER317LSi.
Mamwe 308L maapplication anogona kutsiva 309L sesimbi yekuzadza sezvo asingade molybdenum kusiyana ne316 kana 316L zvikumbiro zvinoda molybdenum saka haugone kutsiva 309 ne316.
Sezvatakaona pamusoro, pane zvakasiyana-siyana zve electrode zviripo. Chimwe nechimwe chazvo chine zvimiro zvakasiyana zvishoma uye saka zvakasiyana zvishoma uye zvakasiyana. Paunenge uchiita chero basa rekugadzirisa nekugadzirisa, kutarisirwa kunofanirwa kutorwa kuve nechokwadi chekuti ma electrode anoshandiswa ane hunhu hunodiwa.
Chekutanga, tarisa rudzi rwesimbi yauchange uchigadzira kana kusevhisi. Ipapo iwe unofanirwa kusarudza kana iwe uchida general chinangwa electrode kana electrode ine yakakosha zvivakwa. Kana uchinge wava neruzivo rwese unokwanisa kutanga kusona, kana ukasashandisa maelectrode asiri iwo solder yako ingangotadza kana kuti unogona kungopisa nesimbi yauri kushanda nayo.
