NHUNGAMIDZO
Kune akawanda akasiyana marudzi emagetsi anoshandiswa mune yakadzivirirwa simbi arc welding, (SMAW) process.Chinangwa chegwaro iri ndechekubatsira nekuzivikanwa uye kusarudzwa kwema electrode aya.
ELECTRODE IDENTIFICATION
Arc welding electrodes inotaridzwa uchishandisa AWS, (American Welding Society) manhamba system uye inogadzirwa muhukuru kubva 1/16 kusvika 5/16.Muenzaniso ungave tsvimbo yewelding inozivikanwa se 1/8" E6011 electrode.
Iyo electrode ndeye 1/8" mudhayamita.
Iyo "E" inomirira arc welding electrode.
Inotevera ichava nhamba ye4 kana 5 manhamba yakadhindwa pa electrode.Nhamba mbiri dzekutanga dzenhamba ine manhamba uye yekutanga manhamba matatu enhamba yenhamba 5 inoratidza kushomeka kwesimba (muzviuru zvemapaundi paskweya inch) yeweld ichaburitswa netsvimbo, kushushikana kwakadzikama.Mienzaniso ingava inotevera:
E60xx inenge iine simba re 60,000 psi E110XX inenge iri 110,000 psi.
Iyo inotevera kune yekupedzisira digit inoratidza nzvimbo iyo electrode inogona kushandiswa mairi.
1.EXX1X ndeyekushandisa munzvimbo dzese
2.EXX2X ndeyekushandisa munzvimbo dzakatsetseka uye dzakachinjika
3.EXX3X ndeye flat welding
Nhamba mbiri dzekupedzisira pamwe chete, dzinoratidza rudzi rwekuputira pa electrode uye welding ikozvino iyo electrode inogona kushandiswa nayo.Zvakadai seDC yakatwasuka, (DC -) DC reverse (DC+) kana AC
Ini handisi kuzotsanangura rudzi rwemachira ema electrode akasiyana, asi ndichapa mienzaniso yemhando iripo imwe neimwe ichashanda nayo.
MA ELECTRODE NEZVINO ZVINOSHANDISWA
● EXX10 DC + (DC reverse kana DCRP) electrode yakanaka.
● EXX11 AC kana DC- (DC yakananga kana DCSP) electrode negative.
● EXX12 AC kana DC-
● EXX13 AC, DC- kana DC+
● EXX14 AC, DC- kana DC+

● EXX27 AC, DC- kana DC+
● EXX28 AC kana DC+
ZVINHU ZVINO
SMAW inoitwa uchishandisa angave AC kana DCcurrent.Sezvo DC ikozvino ichiyerera munzira imwe, DC ikozvino inogona kuve DC yakatwasuka, (electrode negative) kana DC yakadzoserwa (electrode positive).Iine DC yakadzoserwa kumashure, (DC+ OR DCRP) iyo weld kupinda ichave yakadzika.DC yakatwasuka (DC- OR DCSP) iyo weld ichave nekukurumidza kunyungudika uye dhipoziti rate.Iyo weld ichave nepakati pekupinda.
Ac ikozvino inoshandura iyo polarity ka120 pasekondi pachayo uye haigone kuchinjwa sezvingaitwa DC ikozvino.
ELECTRODE SIZE NE AMPS AKASHANDISWA
Izvi zvinotevera zvichashanda segwaro rekutanga reiyo amp renji inogona kushandiswa kune akasiyana saizi maelectrode.Ziva kuti zviyero izvi zvinogona kunge zvakasiyana pakati peakasiyana maelectrode anogadzira eiyo saizi tsvimbo.Zvakare rudzi rwekupfeka pa electrode runogona kuita iyo amperage range.Kana zvichiita, tarisa ruzivo rwekugadzira ye electrode yauchange uchishandisa kune yavo yakakurudzirwa amperage marongero.
Electrode Table
| ELECTRODE DIAMETER (UKObvu) | AMP RANGE | PLATE |
| 1/16" | 20-40 | KUSVIKA 3/16" |
| 3/32" | 40 - 125 | KUSVIRA 1/4" |
| 1/8 | 75 - 185 | PASI 1/8" |
| 5/32" | 105 - 250 | PASI 1/4" |
| 3/16" | 140 - 305 | PASI 3/8" |
| 1/4" | 210 - 430 | PASI 3/8" |
| 5/16" | 275 - 450 | PASI 1/2" |
Cherechedza!Iyo yakakora iyo zvinhu zvinosungirirwa, iyo yakakwirira ikozvino inodiwa uye yakakura iyo electrode inodiwa.
DZIMWE ELECTRODE TYPES
Ichi chikamu chichatsanangura muchidimbu ma electrode mana anowanzoshandiswa pakugadzirisa uye kugadzirisa welding yesimbi yakapfava.Kune mamwe akawanda maelectrode anowanikwa ekubatisa mamwe marudzi esimbi.Tarisa kune waunogara newe welding supply dealer nezve electrode inofanira kushandiswa simbi yaunoda kubatanidza.
E6010Iyi electrode inoshandiswa kune ese chinzvimbo welding uchishandisa DCRP.Inoburitsa yakadzika inopinda weld uye inoshanda zvakanaka patsvina, ngura, kana simbi dzakapendwa
E6011Iyi electrode ine maitiro akafanana eE6010, asi inogona kushandiswa ne AC uye DC currents.
E6013Iyi electrode inogona kushandiswa ne AC uye DC mafungu.Inogadzira weld yepakati inopinda ine weld yemhando yepamusoro.
E7018Iyi electrode inozivikanwa seyakaderera hydrogen electrode uye inogona kushandiswa ne AC kana DC.Iyo yekupfekedza pa electrode ine yakaderera mwando yemukati inoderedza kuiswa kwehydrogen muweld.Iyo electrode inogona kugadzira welds ye x-ray mhando nepakati pekupinda.(Cherechedza, electrode iyi inofanira kugara yakaoma. Kana ikanyorova, inofanira kuomeswa muovheni yetsvimbo isati yashandiswa.)
Zvinotarisirwa kuti ruzivo rwekutanga urwu ruchabatsira mutsva kana wemuchitoro welder kuona marudzi akasiyana-siyana emagetsi uye osarudza iwo chaiwo mapurojekiti avo emagetsi.
