Izinto ngokubanzi malunga ne-Welding Electrodes
I-electrode ye-welding ye-Tianqiao yinketho yobuchwephesha
Ii-electrodes ze-welding zibalulekile, kwaye kubalulekile ukuba umshicileli kunye nabasebenzi abafanelekileyo bazi ukuba loluphi uhlobo lokusetyenziswa kwimisebenzi eyahlukeneyo.
Ziziphi ii-electrode zokuwelda?
I-electrode yintambo yentsimbi egqunywe, eyenziwe ngezinto ezifana nentsimbi edityanisiweyo.Ukuqala, kukho i-electrodes esetyenziswayo kunye ne-non-consumable.Kwi-shield metal arc welding (SMAW) eyaziwa ngokuba yintonga, i-electrodes iyasetyenziswa, oku kuthetha ukuba i-electrode idliwe ngexesha lokusetyenziswa kwayo kwaye inyibilika nge-weld.Kwi-Tungsten Inert Gas welding (TIG) i-electrodes ayinakutyiwa, ngoko ayinyibiliki kwaye ibe yinxalenye ye-weld.Nge-Gas Metal Arc Welding (GMAW) okanye i-MIG ye-welding, i-electrode isoloko iyondliwa ngocingo.I-2 i-arc welding ye-Flux-core idinga i-electrode ye-tubular ye-tubula eqhubekayo yokutya equlethe i-flux.
Indlela yokukhetha i-electrodes ye-welding?
Ukukhetha i-electrode kunqunywe ngeemfuno zomsebenzi we-welding.Ezi ziquka:
- Tensile strength
- I-Ductility
- Ukumelana nokubola
- Isiseko sesinyithi
- Indawo yeWeld
- I-Polarity
- Okwangoku
Kukho i-electrode elayitiweyo elula kwaye enzima.Ii-electrode ezigqunywe ngokukhanya zineengubo zokukhanya ezisetyenziswa ngokuxukuxa, ukutshiza, ukudipha, ukuhlamba, ukosula, okanye ukuwa.Ii-electrode ezigqunywe ngamandla zigqunywe nge-extrusion okanye ukuthontsiza.Kukho iintlobo ezintathu eziphambili zeengubo ezinzima: iminerali, i-cellulose, okanye indibaniselwano yezi zimbini.Iingubo ezinzima zisetyenziselwa ukuwelda intsimbi, iintsimbi kunye neendawo eziqinileyo.
Amanani kunye neeleta zithetha ntoni kwiintonga ze-welding?
I-American Welding Society (i-AWS) inesistim samanani esinika ulwazi malunga ne-electrode ethile, njengokuthi yeyiphi isicelo esisetyenziswe kakuhle kwaye kufuneka iqhutywe njani ukuze kusebenze ubuninzi.
| Idijithi | Uhlobo loKutyabeka | I-Welding yangoku |
| 0 | I-sodium ephezulu ye-cellulose | DC+ |
| 1 | I-potassium ephezulu ye-cellulose | AC, DC+ okanye DC- |
| 2 | I-titania ephezulu ye-sodium | U-AC DC- |
| 3 | I-titania ephezulu ye-potassium | AC, DC+ |
| 4 | Umgubo wentsimbi, i-titania | AC, DC+ okanye DC- |
| 5 | I-sodium ye-hydrogen ephantsi | DC+ |
| 6 | I-hydrogen potassium ephantsi | AC, DC+ |
| 7 | I-iron oxide ephezulu, i-powder potassium | AC, DC+ okanye DC- |
| 8 | I-hydrogen potassium ephantsi, umgubo wentsimbi | AC, DC+ okanye DC- |
I "E" ibonisa i-arc welding electrode.Eyokuqala imivo emibini enamanani anemivo emi-4 kunye nesithathu sokuqala samanani anemivo emi-5 imela amandla okuqina.Umzekelo, i-E6010 ithetha i-60,000 pounds per square inch (PSI) amandla okuqina kunye ne-E10018 ithetha i-100,000 psi amandla okuqina.Idijithi elandelayo ukuya kokugqibela ibonisa indawo.Ngoko, "1" imele i-electrode yonke indawo, "2" i-electrode ecaba kunye ne-horizontal, kunye ne-"4" ye-electrode ecaba, ethe tye, ethe nkqo ezantsi kunye nangaphezulu.Amadijithi amabini okugqibela acacisa uhlobo lokutyabeka kunye ne-welding current.4
| E | 60 | 1 | 10 |
| I-Electrode | Tensile strength | Isikhundla | Uhlobo lweNgqungquthela & yangoku |
Ukwazi iintlobo ezahlukeneyo ze-electrodes kunye nezicelo zabo luncedo ukwenza umsebenzi we-welding ngokuchanekileyo.Uqwalaselo lubandakanya indlela ye-welding, izinto ezidityanisiweyo, iimeko zangaphakathi/zangaphandle, kunye nezikhundla ze-welding.Ukuziqhelanisa nemipu ye-welding eyahlukeneyo kunye nee-electrode kunokukunceda ukuba ubone ukuba yeyiphi i-electrode onokuthi uyisebenzise yeyiphi iprojekthi ye-welding.
