Gusudira arc hifashishijwe amazi ni byiza cyane ku miyoboro, imiyoboro y'amashanyarazi n'ibigega, gukora gari ya moshi no gukoresha mu bwubatsi bunini, hamwe n'imiterere yoroshye ya monofilament, imiterere y'insinga ebyiri, imiterere y'insinga ebyiri hamwe n'imiterere y'insinga nyinshi.
Gusudira arc hifashishijwe amazi bishobora kugirira akamaro abakoresha mu bikorwa byinshi byo gusudira. Kuva ku kongera umusaruro, kunoza aho bakorera, kugeza ku kwemeza ko ubuziranenge buhoraho n'ibindi byinshi. Abakora ibyuma bitunganya ibyuma barimo gutekereza ku mpinduka mu gikorwa cyo gusudira arc hifashishijwe amazi bagombaga gutekereza ko bashobora kubona inyungu nyinshi muri iki gikorwa.
Ubumenyi bw'ibanze ku gusudira arc munsi y'amazi
Uburyo bwo gusudira arc iri munsi y’amazi ni ngombwa mu nganda zikomeye nko mu miyoboro, imiyoboro y’amashanyarazi n’ibigega, kubaka gari ya moshi, kubaka/gucukura bikomeye. Ni byiza ku nganda zisaba umusaruro mwinshi, cyane cyane iyo bigeze ku gusudira ibikoresho binini cyane, hari inyungu nyinshi ziva mu buryo bwo gusudira arc iri munsi y’amazi.
Igipimo cyo hejuru cyo gushyiramo ibintu hamwe n'umuvuduko wo kugenda bishobora kugira ingaruka zikomeye ku musaruro w'abakozi, imikorere myiza n'ikiguzi cy'umusaruro, ibi bikaba ari bimwe mu byiza by'ingenzi byo gusudira arc hifashishijwe amazi.
Izindi nyungu zirimo: imiterere myiza ya chimique n'imiterere ya mekanike y'ubusoda, ubushobozi buke bwo kubona arc n'imyotsi mike yo gusudira, ahantu ho gukorera hameze neza, hamwe n'imiterere myiza ya ubusoda n'umurongo w'amano.
Gusudira arc hifashishijwe amazi ni uburyo bwo gukwirakwiza insinga bukoresha flux y’ibice bito kugira ngo butandukanye arc n’umwuka, nk’uko izina ribigaragaza, arc iba iri mu gusohoka, bivuze ko iyo ibipimo bishyizweho, arc iba itagaragara iyo urwego rw’ingufu rusohoka. Insinga yo gusudira ikomeza gutangwa n’urumuri rugenda ku gusonera.
Gushyushya insinga bishongesha igice cy'insinga, igice cy'umuyoboro n'icyuma cyo hasi, bigakora ikidendezi gishongeshejwe, gihinduka umuyoboro utwikiriwe n'urukuta rw'umuyoboro. Ubunini bw'ibikoresho byo gusudira ni 1/16"-3/4", bushobora kuba 100% by'umuyoboro uvanze, niba ubunini bw'urukuta butari bunini, gusudira hakoreshejwe uburyo bwinshi bushobora gukorwa, kandi gusudira bigatunganywa mbere kandi bigatoranywa, kandi hagatoranywa uburyo bukwiye bwo gusudira insinga.

Guhitamo insinga zo gukurura no gusudira
Guhitamo uburyo bwo gusudira insinga bukwiye mu gihe runaka cyo gusudira insinga ni ingenzi cyane kugira ngo haboneke umusaruro mwiza hakoreshejwe uburyo bwo gusudira insinga. Nubwo uburyo bwo gusudira insinga zonyine ari bwiza, umusaruro n'ubushobozi bishobora kwiyongera ndetse no hashingiwe ku nsinga zo gusudira n'uburyo bwo gusudira bwakoreshejwe.
Iyi flux ntirinda gusa ikigega cyo gusudira, ahubwo inagira uruhare mu kunoza imiterere y’imashini n’umusaruro w’iyi flux. Uburyo iyi flux ikorwamo bigira ingaruka zikomeye kuri ibi bintu, bigira ingaruka ku bushobozi bw’amashanyarazi yo gutwara ndetse no kurekura ifu y’amazi.
Ubushobozi bwo gutwara bukoreshwa ubu busobanura ko hashobora kuboneka ubushobozi bwo gushyiramo ibintu neza cyane ndetse n'uburyo bwo gusudira bufite ireme rihanitse.
Gusohora ifu y'amazi mu buryo runaka bigira ingaruka ku guhitamo ifu y'amazi kuko hari ifu y'amazi ikwiriye cyane imiterere imwe n'imwe y'amazi kurusha izindi.
Amahitamo yo guhitamo flux yo gukoresha arc soldering munsi y’amazi arimo ubwoko bwa welds active na neutral. Itandukaniro ry’ibanze ni uko active flux ihindura shimi ya weld, mu gihe neutral flux idahindura.
Uduce duto dukoreshwa mu gukurura ibintu turangwa no kuba turimo silikoni na manganese. Ibi bintu bifasha mu kugumana imbaraga zo gukurura ibintu ku bushyuhe bwinshi, bifasha mu kugumana utwo duce tworoshye kandi tworoshye ku muvuduko mwinshi w’urugendo kandi bigatanga irekurwa ryiza ry’ibisigazwa. Muri rusange, utwo duce duto dushobora gufasha kugabanya ibyago byo kuba nta bwiza bwo gukurura ibintu, ndetse no gusukura no kongera gukora nyuma yo gukurura ibintu bihenze. Ariko, ibuka ko utwo duce duto dukoreshwa mu gukurura ibintu akenshi tuba dukwiriye cyane mu gukurura ibintu rimwe cyangwa bibiri.
Uduce duto two mu bwoko bwa "neutral flux" ni byiza ku duce duto duto kuko dufasha kwirinda ko habaho uduce duto tworoshye kandi dushobora kwangirika.
Hari ubwoko bwinshi bw'insinga zo gusudira zikoreshwa mu gusudira zinyuze mu mazi, buri imwe ifite ibyiza n'ibibi. Insinga zimwe zakozwe kugira ngo zisudirwe ku bushyuhe bwinshi, mu gihe izindi zakozwe kugira ngo zigire alloys zifasha mu gusudira mu gusudira.
Menya ko imiterere y’ibinyabutabire n’uburyo insinga zikoresha ubushyuhe bigira ingaruka ku miterere y’icyuma gikoreshwa mu gusudira. Umusaruro ushobora kandi kwiyongera cyane no guhitamo ibyuma byuzuza.
Urugero, gukoresha insinga y'icyuma irimo uburyo bwo gusudira arc munsi y'amazi bishobora kongera ubushobozi bwo gushyiramo icyuma ku kigero cya 15% kugeza kuri 30% ugereranije no gukoresha insinga ikomeye, mu gihe binatanga uburyo bwo kwinjira mu buryo bwagutse kandi buto.
Bitewe n'umuvuduko wayo mwinshi mu ngendo, insinga z'icyuma zigabanya ubushyuhe kugira ngo bigabanye ibyago byo kwangirika no gushyuha.
Mu byuma byose, ibyuma bitagira umushongi bya austenitike bifite aho bikura hato cyane. Kubwibyo, mu bijyanye n'imiterere ya mekanike, icyuma kitagira umushongi cya austenitike si cyo gikoresho cyiza ku gice cy'urukiramende, kuko kugira ngo gikomere runaka, umurambararo w'igice cy'urukiramende uziyongera. Aho umusaruro ugarukira ntushobora kwiyongera hakoreshejwe ubushyuhe, ariko ushobora kwiyongera hakoreshejwe ubukonje.
Dufite ububiko bw'imiyoboro ya karuboni n'icyuma kidashonga, murakaza neza niba hari ikibazo, tuzatanga ku nshuro ya mbere!
