INTANGIRIRO
Hari ubwoko bwinshi butandukanye bwa electrode zikoreshwa mu gusudira ibyuma bikingira, (SMAW). Intego y'iyi nyandiko ni ukugufasha kumenya no guhitamo izi electrode.
IMYITOZO Y'AMASHANYARAZI
Ama-electrode yo gusudira arc amenyekana hakoreshejwe sisitemu yo kubara ya AWS, (American Welding Society) kandi akorwa mu bunini kuva kuri 1/16 kugeza 5/16. Urugero rwaba ari inkoni yo gusudira igaragara nka electrode ya 1/8" E6011.
Electrode ifite umurambararo wa 1/8" (1/8").
"E" isobanura electrode yo gusudira arc.
Hazakurikiraho imibare ifite imibare 4 cyangwa 5 iriho ikimenyetso kuri electrode. Imibare ibiri ya mbere y'umubare ufite imibare 4 n'imibare 3 ya mbere y'umubare ufite imibare 5 bigaragaza imbaraga nkeya zo gukurura (mu bihumbi bya pounds kuri santimetero kare) z'ubushuhe inkoni izatanga, ikagabanya umuvuduko. Ingero ni izi zikurikira:
E60xx yaba ifite imbaraga zo gukurura 60.000 psi E110XX yaba 110.000 psi.
Umubare ukurikiraho uhereye ku wa nyuma ugaragaza aho electrode ishobora gukoreshwa.
1.EXX1X ikoreshwa mu myanya yose
2.EXX2X ikoreshwa mu myanya igororotse n'itambitse
3.EXX3X ni iyo gusudira mu buryo burambuye
Imibare ibiri ya nyuma hamwe, igaragaza ubwoko bw'ipamba kuri electrode n'umuyoboro wo gusudira electrode ishobora gukoreshwa. Urugero: DC igororotse, (DC -) DC isubira inyuma (DC+) cyangwa AC
Sinzasobanura ubwoko bw'imyambaro y'amashanyarazi atandukanye, ariko nzatanga ingero z'ubwoko bw'amashanyarazi buri imwe izakoresha.
AMASHANYARAZI N'AMASHANYARAZI YAKORESHEJWE
● EXX10 DC+ (DC reverse cyangwa DCRP) electrode nziza.
● EXX11 AC cyangwa DC- (DC igororotse cyangwa DCSP) electrode negative.
● EXX12 AC cyangwa DC-
● EXX13 AC, DC- cyangwa DC+
● EXX14 AC, DC- cyangwa DC+
● EXX15 DC+
● EXX16 AC cyangwa DC+
● EXX18 AC, DC- cyangwa DC+
● EXX20 AC, DC- cyangwa DC+
● EXX24 AC, DC- cyangwa DC+
● EXX27 AC, DC- cyangwa DC+
● EXX28 AC cyangwa DC+
UBWOKO BW'UBU
SMAW ikorwa hakoreshejwe AC cyangwa DCcurrent. Kubera ko DC current itembera mu cyerekezo kimwe, DC current ishobora kuba DC straight, (electrode negative) cyangwa DC reversed (electrode positive). Iyo DC reversed, (DC+ CYANGWA DCRP) kwinjira kwa weld kuzaba kure cyane. DC straight (DC- CYANGWA DCSP) weld izaba ifite igipimo cyo gushonga vuba no kwinjizwa. Weld izaba ifite igice cyo kwinjira kiri hagati.
Umuriro w'amashanyarazi uhindura polarite yawo inshuro 120 ku isegonda ubwayo kandi ntushobora guhinduka nk'uko umuriro wa DC ushobora guhinduka.
INGANO YA ELECTRODE NA AMPS ZAKORESHEJWE
Ibi bikurikira bizagufasha nk'ubuyobozi bw'ibanze bw'urwego rw'amashanyarazi rushobora gukoreshwa kuri electrode z'ingano zitandukanye. Menya ko ibi bipimo bishobora gutandukana hagati y'inganda zitandukanye zikora electrode ku nkoni imwe. Nanone ubwoko bw'igitambaro kuri electrode bushobora kugira ingaruka ku rugero rw'amashanyarazi. Iyo bishoboka, reba amakuru y'inganda zikora electrode uzakoresha kugira ngo ubone imiterere y'amashanyarazi zisabwa.
Ameza ya Electrode
| IGIPIMO CY'AMASHANYARAZI (UBUNINI) | URUGERO RWA AMP | ISAHANI |
| 1/16" | 20 - 40 | KUGEZA KURI 3/16" |
| 3/32" | 40 - 125 | KUGEZA KURI 1/4" |
| 1/8 | 75 - 185 | IRENZE 1/8" |
| 5/32" | 105 - 250 | IRENZE 1/4" |
| 3/16" | 140 - 305 | IRENZE 3/8" |
| 1/4" | 210 - 430 | IRENZE 3/8" |
| 5/16" | 275 - 450 | IRENZE 1/2" |
Icyitonderwa! Uko ibikoresho bigomba gusudira birushaho kuba binini, ni ko umuriro ukenewe uba mwinshi kandi electrode ikaba nini.
UBWOKO BUMWE NA BUMWE BWA ELECTRODE
Iki gice kizasobanura muri make electrode enye zikoreshwa mu kubungabunga no gusana ubudozi bw'icyuma cyoroshye. Hariho izindi electrode nyinshi zikoreshwa mu gusudira ubundi bwoko bw'ibyuma. Baza umucuruzi w'ibikoresho byo gusudira wo mu gace utuyemo niba ari electrode ikwiye gukoreshwa mu byuma ushaka gusudira.
E6010Iyi electrode ikoreshwa mu gusudira ahantu hose hakoreshejwe DCRP. Ikora isudiro yinjirira cyane kandi ikora neza ku byuma byanduye, byangiritse, cyangwa byasizwe irangi.
E6011Iyi electrode ifite imiterere imwe ya E6010, ariko ishobora gukoreshwa hamwe n'imigezi ya AC na DC.
E6013Iyi electrode ishobora gukoreshwa hamwe n'imiyoboro ya AC na DC. Ikora isudi iciriritse igeramo ifite ishusho nziza y'ubushudi.
E7018Iyi electrode izwi nka electrode ifite hydrogen nkeya kandi ishobora gukoreshwa hamwe na AC cyangwa DC. Irangi riri kuri iyo electrode rifite ubushuhe buke bugabanya kwinjira kwa hydrogen mu cyuma. Iyo electrode ishobora gukora ibyuma bifite ubushuhe bwa x-ray hamwe n'uburyo buciriritse bwo kwinjira. (Icyitonderwa, iyi electrode igomba kuguma yumye. Iyo itose, igomba kuyumishwa mu itanura mbere yo kuyikoresha.)
Hari icyizere ko aya makuru y'ibanze azafasha umusudi mushya cyangwa umucuruzi wo mu rugo kumenya ubwoko butandukanye bwa electrode no guhitamo ikwiye imishinga ye yo gusudira.
