Izinto ezijwayelekile Mayelana ne-Welding Electrodes
I-electrode yokushisela i-Tianqiao iyindlela yobuchwepheshe
Ama-electrode okushisela abalulekile, futhi kubalulekile ukuthi umshicileli kanye nabasebenzi abafanelekile bazi ukuthi yiluphi uhlobo okufanele lusetshenziswe emisebenzini ehlukene.
Ayini ama-electrode welding?
I-electrode iyintambo yensimbi eboshwe, eyenziwe ngezinto ezifana nensimbi eshiselwayo.Okokuqala, kukhona ama-electrode asebenzisekayo futhi angasebenziseki.Ku-shield metal arc welding (SMAW) eyaziwa nangokuthi induku, ama-electrode ayasebenziseka, okusho ukuthi i-electrode idliwe ngesikhathi sokusetshenziswa kwayo futhi incibilika ne-weld.Ku-Tungsten Inert Gas welding (TIG) ama-electrodes awasebenziseki, ngakho awancibiliki futhi abe yingxenye yokushisela.Nge-Gas Metal Arc Welding (GMAW) noma i-MIG welding, ama-electrode anikezwa izintambo ngokuqhubekayo.2 I-Flux-cored arc welding idinga i-electrode ye-tubular esetshenziswa ngokuqhubekayo equkethe i-flux.
Ungakhetha kanjani ama-electrode welding?
Ukukhetha i-electrode kunqunywa yizidingo zomsebenzi wokushisela.Lokhu kubandakanya:
- Amandla aqinile
- I-Ductility
- Ukumelana nokugqwala
- Isisekelo sensimbi
- Isikhundla se-Weld
- I-polarity
- Okwamanje
Kukhona ama-electrode acwebezelayo alula futhi asindayo.Ama-electrode agqinsiwe anokukhanya asetshenziswa ngokuxubha, ngokufuthwa, ukucwiliswa, ukuwashwa, ukwesula, noma ukuwa.Ama-electrode aqinile aboshwe ngokukhipha noma ukuconsa.Kunezinhlobo ezintathu eziyinhloko zezingubo ezisindayo: amaminerali, i-cellulose, noma inhlanganisela yakho kokubili.Izindwangu ezisindayo zisetshenziselwa ukushisela insimbi ekhonjiwe, izinsimbi, kanye nendawo eqinile.
Zisho ukuthini izinombolo nezinhlamvu ezindongeni zokushisela?
I-American Welding Society (AWS) inohlelo lwezinombolo olunikeza ulwazi mayelana ne-electrode ethile, njengokuthi yiluphi uhlelo lokusebenza olusetshenziswa kangcono nokuthi kufanele lusetshenziswe kanjani ukuze lusebenze kahle kakhulu.
| Idijithi | Uhlobo Lokunamathela | I-Welding Yamanje |
| 0 | I-sodium ephezulu ye-cellulose | I-DC+ |
| 1 | I-potassium ephezulu ye-cellulose | I-AC, DC+ noma i-DC- |
| 2 | I-titania ephezulu ye-sodium | AC, DC- |
| 3 | I-titania ephezulu ye-potassium | AC, DC+ |
| 4 | I-iron powder, i-titania | I-AC, DC+ noma i-DC- |
| 5 | I-sodium ye-hydrogen ephansi | I-DC+ |
| 6 | I-hydrogen potassium ephansi | AC, DC+ |
| 7 | I-iron oxide ephezulu, i-potassium powder | I-AC, DC+ noma i-DC- |
| 8 | I-hydrogen potassium ephansi, i-iron powder | I-AC, DC+ noma i-DC- |
I-“E” ikhombisa i-arc welding electrode.Amadijithi amabili okuqala enomboro enamadijithi ama-4 kanye namadijithi amathathu okuqala enomboro enezinombolo ezi-5 amelela amandla aqinile.Isibonelo, i-E6010 isho amaphawundi angu-60,000 ngentshi yesikwele (PSI) amandla aqinile futhi u-E10018 usho amandla angu-100,000 we-psi.Idijithi elandelayo kuya kokugcina ikhombisa indawo.Ngakho, u-“1” umele i-electrode yonke indawo, “2” imele i-electrode eyisicaba nevundlile, futhi “4” imele i-electrode eyisicaba, evundlile, eqondile eya phansi nangaphezulu.Amadijithi amabili okugcina acacisa uhlobo lwe-coating kanye ne-welding current.4

Ukwazi izinhlobo ezahlukene zama-electrode kanye nezicelo zabo kuyasiza ukwenza umsebenzi wokushisela ngendlela efanele.Okucatshangelwayo kuhlanganisa indlela yokushisela, izinto ezishiselwe, izimo zangaphakathi/zangaphandle, kanye nezikhundla zokushisela.Ukuzijwayeza ngezibhamu zokushisela ezihlukahlukene kanye nama-electrode kungakusiza ukunquma ukuthi iyiphi i-electrode ongayisebenzisela ukuthi iyiphi iphrojekthi yokushisela.
