Electrode iyi iwaya yesimbi yakafukidzwa uye inofanira kugadzirwa nezvinhu zvakafanana muhunhu uye musanganiswa wesimbi iri kusungirirwa, uye pane zvinhu zvakawanda zvinobatanidzwa pakusarudza electrode yakakodzera purojekiti yako.
Kunyange zvazvo ma electrode esimbi akavharirwa (SMAW) kana kuti "stick" achigona kushandiswa uye anova chikamu che weld, mamwe ma electrode (akadai seaya anoshandiswa pa TIG welding) haagone kushandiswa, zvichireva kuti haanyunguduki uye anova chikamu che weld. Muzviitiko izvi, kushandiswa kwe electrode kunodiwa.
Isu vekuEng-weld tinoziva kuti kusarudza electrode yakakodzera kwakakosha pakusimbisa simba re weld, kunaka kwe weld, kuderedza kupfapfaidza uye kuchenesa.
Maelectrode eCellulose maelectrode ekuwedera akaputirwa nesheath ine zvinhu zveorganic. Kazhinji inenge 30% yehuremu hwependi inova cellulose, asi mune dzimwe nzvimbo dzepasi rose cellulose nehupfu hwehuni zvinogona kuwedzerwa pendi kuti zvideredze huwandu hwe cellulose yakachena.
Makemikoro akasiyana-siyana ari mumaerekitironi anoora muarc kuti agadzire kabhoni diokisijeni, kabhoni monoxide nehydrogen, zvese izvi zvinowedzera voltage mukati mearc, zvichikonzera arc yakasimba uye yakaoma. Saka, maerekitironi ecellulose anogona kupinda kusvika 70% zvakadzika kupfuura maerekitironi anoenderana ane chiyero chakafanana chemazuva ano.
Kazhinji inogadzirwa nejira rakatetepa kana repakati, kunyangwe izvi zvichiburitsa tsvina inogona kubviswa mushure mekunge maitiro ekunamira apera, izvi zvinogona kukonzera kurasikirwa kukuru kwekunamira. Zvisinei, kugona kwenamira pasi uye kugona kwekupinda kweelectrode iyi zvakanaka kwazvo nekuda kwekuzadza gap mujira.
Electrode yehydrogen yakaderera inonyanya kushandiswa negesi yakavharirwa arc welding (SMAW) ine mvura iri pasi pe0.6% zvichienzaniswa ne4-6% yemvura yemazuva ano yemaelectrode e cellulosic.
Kazhinji, maerekitironi asina hydrogen akawanda akadai seE7018 rod electrode anopa vashandisi mvura shoma uye arc yakatsetseka, yakagadzikana uye yakanyarara. Hunhu uhwu hunoita kuti maerekitironi aya ave sarudzo yakanaka kune vese vane ruzivo rwekuwelders nevanotanga. Hunhu hwemaerekitironi aya esimbi anozadza hunoita kuti welder ive nekutonga kwakanaka kwearc uye inoderedza kudiwa kwekucheneswa mushure mekuwelders.
Kusiyana nemamwe maerekitironi akadai seE6010 kana E6011, maerekitironi ehydrogen akaderera anopa mukana wekuisa zvinhu zvakanaka uye mwero wekupinda, zvichibvumira muchina wekusonera kuwedzera simbi kune joint chero nguva, zvichivandudza simba rekusonera uye kudzivirira zvikanganiso zvekusonera zvakaita sekushaya pendi.
Kazhinji, maerekitironi esimbi isina kusimba anopa arc yakanyarara uye yakagadzikana ine kupinda kwakaderera, zvichiita kuti akwanise kushandiswa pakubatanidza mipata yakakura uye jira rakatetepa. Zvisinei, kune mhando dzakasiyana dzemaerekitironi esimbi isina kusimba, rimwe nerimwe rine hunhu hwakasiyana zvishoma uye nekudaro rakanyatsokodzera kushandiswa kwakasiyana.
Semuenzaniso, giredhi 6013 ielectrode yesimbi yakapfava inoshandiswa zvakanyanya iyo inopa kupinda kwakadzika uku ichichengetedza arc yakatsetseka uye yakagadzikana. Arc iri nyore kugadzirazve, musono wekuwelda wakanaka, kupwanya kwacho kwakaderera, slag iri nyore kudzora, yakakodzera welding yakatwasuka.
Electrode ye7018 arc, kune rumwe rutivi, ielectrode yesimbi isina simba rakawanda yakagadzirirwa kusundira zvinhu zvesimbi ine kabhoni yakasimba. Electrode iyi inowanzoshandiswa pakusundira simbi nekuda kwekusagadzikana kweweld. Asi izvi zvinogadzira slag yakawanda, iyo isingakodzeri kusundira pasi.
Electrode yesimbi yakapfava yekupedzisira yatichaona i6011. Iyi electrode inopinza yakadzika inopa arc yakapfava uye yakagadzikana pakusanganisa simbi yakapfava yakagadzikwa uye dzimwe simbi dzisina alloy. Kuputira kwayo kunoita arc ine simba yekupinda yakadzika, uye slag layer yakatetepa uye iri nyore kubvisa.
Kufanana nemamwe maelectrode atakaona pamusoro apa, maelectrode esimbi isina ngura anouya mumhando dzakasiyana-siyana, imwe neimwe yakasiyana zvishoma neyapfuura.
Pano tinotarisa mhando nhatu dzakasiyana dzemaelectrode esimbi isingatsvi, 308, 309 ne316, uye kuti dzinoshandiswa riini.
Kana uchishandisa magiredhi 301, 302, 304, 305 uye ma alloys ekukanda CF-3 neCF8, saka tinokurudzira kuti ushandise 308L, kusanganisira ma electrodes eER308LSi. Aya ma electrodes esimbi isina ngura akanakira simbi dzisina ngura dzinoshandiswa mu austenitic, asi pamashandisirwo akadai sekugadzira magetsi, tinokurudzira 308H electrode sezvo iyi electrode ine kabhoni yakawanda inopa simba rekudzivirira kukwira kwemvura pakupisa kwakanyanya.
Kana uchibatanidza simbi isina ngura kana simbi isina ngura kusimbi isina ngura, shandisa 309L, kusanganisira ER309LSi. Izvi zvinoshandawo pakubatanidza simbi dzakasiyana-siyana dzisina ngura dzakadai se409 kana 304L isina ngura. Pamusoro peizvi, dzinofanirawo kushandiswa kubatanidza simbi dzepasi dze309.
Pakushandisa simbi dzesimbi dzebase 316L ne316 pamwe chete neCF-8m neCF-3M, 316L chete ndiyo inofanira kushandiswa sesimbi yekuzadza, kusanganisira ER317LSi.
Mamwe mashandisirwo e308L anogona kutsiva 309L sesimbi yekuzadza sezvo asingade molybdenum kusiyana nemashandisirwo e316 kana 316L anoda molybdenum saka haugone kutsiva 309 ne316.
Sezvataona pamusoro apa, kune mhando dzakasiyana dzema electrode dziripo. Rimwe nerimwe rawo rine hunhu hwakasiyana zvishoma uye nekudaro hunhu hwakasiyana zvishoma uye hwakasiyana. Paunenge uchiita chero basa rekugadzirisa nekugadzirisa, kungwarira kunofanirwa kuitwa kuona kuti ma electrode anoshandiswa ane hunhu hunodiwa.
Kutanga, sarudza rudzi rwesimbi yauchagadzirisa kana kugadzirisa. Wobva wasarudza kana uchida electrode inoshandiswa zvakanyanya kana electrode ine hunhu hwakakosha. Kana wangowana ruzivo urwu rwese unogona kutanga kusundira, kana ukasashandisa maelectrode asiri iwo, solder yako ingangokundikana kana kuti unogona kungopisa simbi yauri kushanda nayo.
