INTSHAYELELO
Kukho iintlobo ezininzi ezahlukeneyo ze-electrode ezisetyenziswa kwi-shielded metal arc welding, (SMAW) inkqubo.Injongo yesi sikhokelo kukunceda ngokuchongwa kunye nokukhethwa kwezi electrode.
UKUCHONGWA KWE-ELECTRODE
I-Arc welding electrodes ichongiwe ngokusebenzisa i-AWS, (i-American Welding Society) inkqubo yokubala amanani kwaye yenziwe ngobukhulu ukusuka kwi-1/16 ukuya kwi-5/16.Umzekelo uyakuba yintonga yewelding echongwe njenge-1/8" E6011 electrode.
I-electrode yi-1/8" ububanzi.
U-"E" umele i-arc welding electrode.
Okulandelayo kuya kuba yinombolo eneedijithi ezi-4 okanye ezi-5 ezigximfizwe kwi-electrode.Amanani amabini okuqala amanani ama-4 kunye ne-3 yokuqala yenombolo ye-5 amanani abonisa ubuncinci bokuqina kwamandla (ngamawaka eeponti nge-intshi nganye yesikwere) ye-weld eya kuvelisa intonga, iyancipha uxinzelelo.Imizekelo iya kuba ngolu hlobo lulandelayo:
I-E60xx iya kuba namandla e-tensile ye-60,000 psi E110XX iya kuba yi-110,000 psi.
Idijithi elandelayo ukuya kokugqibela ibonisa indawo enokusetyenziswa kuyo i-electrode.
1.EXX1X yeyokusetyenziswa kuzo zonke izikhundla
I-2.EXX2X yeyokusetyenziswa kwiindawo ezisicaba kunye nezithe tye
3.EXX3X yeyokuwelda flat
Amadijithi amabini okugqibela kunye, abonisa uhlobo lokutyabeka kwi-electrode kunye ne-welding yangoku i-electrode ingasetyenziswa nayo.Ezinje nge DC ngqo, (DC -) DC umva (DC+) okanye AC
Andiyi kuchaza uhlobo lweengubo zee-electrode ezahlukeneyo, kodwa ndiya kunika imizekelo yohlobo lwangoku nganye eya kusebenza nayo.
II-ELECTRODE KUNYE NEZIGCAWU EZISETYENZISWAYO
● EXX10 DC + (DC reverse okanye DCRP) electrode positive.
● EXX11 AC okanye DC- (DC straight okanye DCSP) electrode negative.
● EXX12 AC okanye DC-
● EXX13 AC, DC- okanye DC+
● EXX14 AC, DC- okanye DC+
● EXX15 DC+
● EXX16 AC okanye DC+
● EXX18 AC, DC- okanye DC+
● EXX20 AC ,DC- okanye DC+
● EXX24 AC, DC- okanye DC+
● EXX27 AC, DC- okanye DC+
● EXX28 AC okanye DC+
IINTLOBO ZAMANJE
I-SMAW yenziwa kusetyenziswa nokuba yi-AC okanye i-DCcurrent.Ekubeni i-DC yangoku ihamba kwicala elinye, i-DC yangoku inokuba yi-DC ngqo, (i-electrode negative) okanye i-DC iguqulwe (i-electrode positive).Nge-DC ebuyiselwe umva, (DC+ OKANYE DCRP) ukungena kwe-weld kuya kuba nzulu.I-DC straight (DC- OKANYE DCSP) i-weld iya kuba nesantya sokunyibilika ngokukhawuleza kunye nediphozithi.I-weld iya kuba nokungena okuphakathi.
I-Ac yangoku iyayitshintsha i-polarity ka-120 umphinda-phinde ngomzuzwana ngokuzimela kwayo kwaye ayinakuguqulwa njengokuba inokwenza i-DC yangoku.
Ubukhulu be-ELECTRODE KUNYE NE-AMPS EZISETYENZISWAYO
Oku kulandelayo kuya kusebenza njengesikhokelo esisisiseko soluhlu lwe-amp olungasetyenziselwa ubungakanani be-electrode ezahlukeneyo.Qaphela ukuba ezi reyithingi zinokwahluka phakathi kwee-electrode ezahlukeneyo ezivelisa ubungakanani bentonga efanayo.Kwakhona uhlobo lokutyabeka kwi-electrode lunokwenza uluhlu lwe-amperage.Xa kunokwenzeka, jonga ulwazi lokwenziwa kwe-electrode oza kuyisebenzisela useto olucetyiswayo lwe-amperage.
Itheyibhile ye-Electrode
| I-ELECTRODE DIAMETER (UBUBANDUKA) | Uluhlu lwe-AMP | IPLATE |
| 1/16" | 20 - 40 | UKUYA KU-3/16" |
| 3/32" | 40 - 125 | UKUYA KU 1/4" |
| 1/8 | 75 - 185 | NGAPHEZU kwe-1/8" |
| 5/32" | 105 - 250 | NGAPHEZU kwe-1/4" |
| 3/16" | 140 - 305 | NGAPHEZU kwe-3/8" |
| 1/4" | 210 - 430 | NGAPHEZU kwe-3/8" |
| 5/16" | 275 - 450 | NGAPHEZU kwe-1/2" |
Phawula!Izinto ezityebileyo ezizakudityaniswa, kokukhona iphezulu imfuneko yangoku kunye ne-electrode enkulu efunekayo.
EZINYE IINTLOBO ZE-ELECTRODE
Eli candelo liza kuchaza ngokufutshane i-electrode ezine eziqhelekileyo ezisetyenziselwa ukugcinwa kunye nokulungiswa kwe-welding yensimbi epholileyo.Zininzi ezinye ii-electrodes ezifumanekayo zokuwelda ezinye iintlobo zesinyithi.Jonga kumthengisi we-welding yengingqi yakho malunga ne-electrode ekufuneka isetyenziselwe intsimbi ofuna ukuyidibanisa.
E6010Le electrode isetyenziselwa yonke indawo welding usebenzisa DCRP.Ivelisa i-weld ejulileyo kwaye isebenza kakuhle kwiintsimbi ezimdaka, eziruliweyo, okanye ezipeyintiweyo
E6011Le electrode ineempawu ezifanayo ze-E6010, kodwa ingasetyenziswa kunye ne-AC kunye ne-DC currents.
E6013Le electrode ingasetyenziswa kunye AC kunye DC imisinga.Ivelisa i weld engeneyo ephakathi enenkangeleko yebead ephezulu.
E7018Le electrode yaziwa ngokuba yi-electrode ye-hydrogen ephantsi kwaye ingasetyenziswa kunye ne-AC okanye i-DC.I-coating kwi-electrode inomswakama ophantsi onciphisa ukuqaliswa kwe-hydrogen kwi-weld.I-electrode inokuvelisa iiwelds zomgangatho we-x-ray ngokungena okuphakathi.(Qaphela, le electrode kufuneka igcinwe yomile. Ukuba iba manzi, kufuneka yomiswe kwi-oven yentonga phambi kokuba isetyenziswe.)
Kuyathenjwa ukuba olu lwazi lusisiseko luya kunceda i-welder entsha okanye ivenkile yasekhaya ibone iintlobo ezahlukeneyo ze-electrode kwaye ikhethe eyona ichanekileyo kwiiprojekthi zabo ze-welding.
