ISINGENISO
Kunezinhlobo eziningi ezahlukene zama-electrode asetshenziswa ku-shielded metal arc welding, (SMAW) inqubo.Inhloso yalo mhlahlandlela ukusiza ngokuhlonza nokukhethwa kwalawa ma-electrode.
ELECTRODE IDENTIFICATION
Ama-electrodes we-arc welding ahlonzwa kusetshenziswa uhlelo lwezinombolo lwe-AWS, (American Welding Society) futhi enziwa ngosayizi ukusuka ku-1/16 kuya ku-5/16.Isibonelo kungaba induku yokushisela ekhonjwe njenge-electrode engu-1/8" E6011.
I-electrode ingu-1/8" ububanzi.
I-"E" imele i-arc welding electrode.
Okulandelayo kuzoba inombolo enamadijithi angu-4 noma angu-5 egxivizwe ku-electrode.Izinombolo zokuqala ezimbili zenombolo eyidijithi engu-4 kanye namadijithi angu-3 okuqala enomboro enezinombolo ezingu-5 zibonisa ubuncane bamandla okuqina (ezinkulungwaneni zamaphawundi ngeyintshi yesikwele) ye-weld ezokhiqizwa induku, ukucindezeleka kuphelile.Izibonelo zizoba kanje:
I-E60xx ingaba namandla we-tensile angu-60,000 psi E110XX ingaba ngu-110,000 psi.
Idijithi elandelayo kuya kokugcina ikhombisa indawo lapho i-electrode ingasetshenziswa khona.
1.EXX1X isetshenziswa kuzo zonke izikhundla
I-2.EXX2X isetshenziswa ezindaweni eziyisicaba nezivundlile
I-3.EXX3X eye-welding flat
Amadijithi amabili okugcina ahlangene, akhombisa uhlobo lokugqoka ku-electrode kanye ne-welding yamanje i-electrode engasetshenziswa nayo.Okufana ne-DC straight, (DC -) DC reverse (DC+) noma i-AC
Ngeke ngichaze uhlobo lwezingubo zama-electrode ahlukahlukene, kodwa ngizonikeza izibonelo zohlobo lwamanje ngamunye azosebenza ngalo.
AMA-ELECTRODE KANYE NEZIMALI EZISETSHENZISWAYO
● EXX10 DC+ (DC reverse noma DCRP) electrode positive.
● EXX11 AC noma DC- (DC straight or DCSP) electrode negative.
● EXX12 AC noma i-DC-
● EXX13 AC, DC- noma DC+
● EXX14 AC, DC- noma DC+
● EXX15 DC+
● EXX16 AC noma i-DC+
● EXX18 AC, DC- noma DC+
● EXX20 AC ,DC- noma i-DC+
● EXX24 AC, DC- noma DC+
● EXX27 AC, DC- noma DC+
● EXX28 AC noma i-DC+
IZINHLOBO ZAMANJE
I-SMAW yenziwa kusetshenziswa i-AC noma i-DCcurrent.Njengoba i-DC current igeleza ohlangothini olulodwa, i-DC yamanje ingaba i-DC iqonde, (i-electrode negative) noma i-DC ihlehliswe (i-electrode positive).Uma i-DC ihlehlisiwe,(DC+ NOMA DCRP) ukungena kwe-weld kuzojula.I-DC straight (DC- NOMA DCSP) i-weld izoncibilika ngokushesha kanye nezinga lediphozithi.I-weld izoba nokungena okuphakathi.
I-Ac current ishintsha i-polarity izikhathi ezingu-120 ngesekhondi ngokwayo futhi ayikwazi ukushintshwa njengoba ingenza i-DC yamanje.
USIZI KA-ELECTRODE KANYE NE-AMPS ESETSHENZISWAYO
Okulandelayo kuzosebenza njengomhlahlandlela oyisisekelo wobubanzi be-amp obungasetshenziswa kuma-electrode osayizi abahlukene.Qaphela ukuthi lezi zilinganiso zingahluka phakathi kwabakhiqizi abahlukahlukene be-electrode yenduku yosayizi ofanayo.Futhi uhlobo olunamathelayo ku-electrode lungenza uhla lwe-amperage.Uma kungenzeka, hlola ulwazi lomkhiqizi we-electrode ozobe uyisebenzisela izilungiselelo zabo ezinconyiwe ze-amperage.
Ithebula le-Electrode
| I-ELECTRODE DIAMETER (UBUDILI) | I-AMP RANGE | PLATE |
| 1/16" | 20 - 40 | UKUFIKA KU-3/16" |
| 3/32" | 40 - 125 | KUFIKA KU-1/4" |
| 1/8 | 75 - 185 | NGAPHEZU kuka-1/8" |
| 5/32" | 105 - 250 | NGAPHEZU kuka-1/4" |
| 3/16" | 140 - 305 | NGAPHEZU kuka-3/8" |
| 1/4" | 210 - 430 | NGAPHEZU kuka-3/8" |
| 5/16" | 275 - 450 | NGAPHEZU kuka-1/2" |
Qaphela!Ukuqina kwezinto okufanele zishiselwe, kuyanda okwamanje okudingekayo kanye ne-electrode enkulu edingekayo.
EZINYE IZINHLOBO ZE-ELECTRODE
Lesi sigaba sizochaza kafushane ama-electrode amane avame ukusetshenziselwa ukugcinwa nokulungisa ukushisela kwensimbi emnene.Maningi amanye ama-electrode atholakalayo okushisela ezinye izinhlobo zezinsimbi.Hlola nomthengisi wendawo yangakini mayelana ne-electrode okufanele isetshenziselwe insimbi ofuna ukuyishisela.
E6010Le electrode isetshenziselwa yonke indawo yokushisela usebenzisa i-DCRP.Ikhiqiza i-weld ejulile engena futhi isebenza kahle ezinsimbi ezingcolile, ezigqwalile, noma ezipendiwe
E6011Le electrode inezici ezifanayo ze-E6010, kodwa ingasetshenziswa ne-AC kanye ne-DC currents.
E6013Le electrode ingasetshenziswa ne-AC kanye ne-DC currents.Ikhiqiza ukushisela okuphakathi nendawo nokubukeka kobuhlalu obusezingeni eliphezulu.
E7018Le electrode yaziwa njenge-electrode ephansi ye-hydrogen futhi ingasetshenziswa ne-AC noma i-DC.I-coating on the electrode inomswakama ophansi onciphisa ukwethulwa kwe-hydrogen ku-weld.I-electrode ingakhiqiza ama-welds wekhwalithi ye-x-ray ngokungena okuphakathi.(Qaphela, le electrode kufanele igcinwe yomile. Uma iba manzi, kufanele yomiswe kuhhavini wenduku ngaphambi kokusetshenziswa.)
Kwethenjwa ukuthi lolu lwazi oluyisisekelo luzosiza umshiseli omusha noma wesitolo sasekhaya ukuthi abone izinhlobo ezahlukene zama-electrode futhi akhethe okulungile kumaphrojekthi abo wokushisela.
