Welding chinhu chakakosha mumaindasitiri mazhinji. Kusanganisa nekugadzirisa simbi kuita zvimiro uye zvigadzirwa zvinoda nyanzvi dzine hunyanzvi dzakadzidza hunyanzvi hwavo kubva kumudzidzi kusvika pahunyanzvi kubva pakutanga. Kutarisa kune zvakadzama kunogadzirira welder yakakura, uye welding yakakura inokosheswa zvakanyanya muzvitoro zvakawanda zvekugadzira. Sezvo otomatiki ichiramba ichifashama hunyanzvi hwekuita, welding inoramba iri hunyanzvi husingagone kurobhotiswa zvizere, uye vakadzidza welders vanogara vachidiwa.
Stick Welding/Arc Welding (SMAW)
Stick welding inozivikanwawo se shielded metal arc welding (SMAW). Mune nzira iyi yekugadzira, welder anoshandisa tsvimbo yekuputika mugwaro rekushandisa, achishandisa magetsi ekugadzira arc pakati petsvimbo nesimbi kuti zvibatanidzwe. Iyi nzira inowanzoshandiswa pakuvaka zvivakwa zvesimbi uye mukugadzirwa kwemaindasitiri kune weld simbi. Welder anoshandisa nzira iyi anofanira kuva neunyanzvi hwakakwana kuti apfuure weld simbi kuburikidza neanoparadza bend test. Iyi nzira iri nyore kudzidza, asi inoda nguva refu yekudzidza kuti uve tenzi. Stick welding zvakare haigadziri yakanakisa kupedzisa, saka yakanakisa kuchengeterwa welds isingaonekwe muchigadzirwa chakapedzwa. Iyi nzira yakanaka pakugadzirisa midziyo nekuti inoshanda panzvimbo dzine ngura, dzakapendwa uye dzine tsvina.
Metal inert gasi (MIG) welding kana GMAW
Gasi Metal Arc Welding (GMAW) inozivikanwawo seMIG (Metal Inert Gas) welding. Iyi nzira yewelding inoshandisa gasi rekudzivirira pamwe chete nemagetsi uyezve inopisa simbi mbiri kuti dzibatanidzwe. Iyi nzira inoda mhepo isingaperi kubva kuDC magetsi sosi uye ndiyo inonyanya kushandiswa mumaindasitiri welding process. Iyi nzira yakanakira welding gobvu sheet simbi kuita yakachinjika chinzvimbo.
Tungsten Inert Gasi (TIG) Welding (GTAW)
Gasi tungsten shielded welding (GTAW), inozivikanwawo seTIG (tungsten inert gas) welding, inonyanya kushandiswa kubatanidza zvikamu zvakakora zvesimbi isina tsvina kana isina-ferrous simbi. Iyi ndiyo imwe arc welding process iyo inokwenenzverwa neyakagadziriswa consumable tungsten electrode, asi maitiro acho anotora nguva yakawanda kupfuura tsvimbo kana MIG welding. Kuumbwa kwesimbi yepasi kwakakosha zvikuru kana uchishandisa nzira iyi, sezvo chikamu chekromium chinokanganisa kupisa kwekunyunguduka. Iyi mhando ye welding inogona kuitwa pasina filler simbi. Nekuda kwekugara kwegasi kuyerera kunodiwa, iyi nzira inonyanya kuitwa mukamuri iri kure nemamiriro ezvinhu. TIG welding inogadzira maweld akanaka, asi inonetsa kubata uye inoda munhu ane ruzivo uye ane hunyanzvi.
Flux cored arc welding
Flux cored arc welding (FCAW) yakagadziridzwa seimwe nzira kune yakadzivirirwa welding. Iyi nzira inokurumidza uye inotakurika, uye ndiyo nzira inonyanya kushandiswa muzvirongwa zvekuvaka. Inoshandiswa mumhando dzakasiyana-siyana dzekugadzira mapurojekiti uye inopa kuchinjika kukuru mumakona, voltage, polarity uye kumhanya. Mhando iyi yewelding inonyanya kuitwa kunze kana pasi pehutsi hwehutsi sezvo ichigadzira utsi hwakawanda panguva yekuita.
Zvisinei nemhando yewelding inoshandiswa kune yako tsika yekugadzira simbi purojekiti, zvakakosha kuve nehunyanzvi hwekunama anonzwisisa kuoma kwenzira yega yega uye simbi dzavanoshanda nadzo. Chigadzirwa chekugadzira simbi yemhando yepamusoro chichava nechikwata chakasimba chevacheki vanodada nehunyanzvi hwavo uye vanogona kurumbidza yakanakisa mhando yeweld yepurojekiti yega yega.
