Kugadzirisa welds pazvinhu zvisingazivikanwe?Heano mamwe matipi ekukubatsira kuona zvauri kutengeswa.Getty Images
Mubvunzo: Basa rangu rinosanganisira pa-site machine shop welding nekugadzirisa michina uye zvivakwa.Ini handisati ndamboudzwa kuti rudzii rwesimbi yandiri kusosa.Munogona here kundipa nhungamiro yekuti ndingaziva sei rudzi uye giredhi resimbi yandiri kushandisa?
A: Zano rakanakisisa randinogona kupa nderekuti usaedza kuitengesa kana iwe usingazivi kuti chii.Izvi ndezvechokwadi kunyanya kune zvikamu zvakakosha apo kukundikana kunogona kukonzera kukuvara kana rufu.
Welding pane dzimwe simbi uchishandisa nzira dzisina kufanira welding zvinogona kukonzera kukanganisa mu base simbi, weld, kana zvese.
Kana ukakumbirwa kuti usimbise chinhu chisingazivikanwi, unoziva sei kuti chii?Chokutanga, unofanira kukwanisa kushandisa kuongorora kwekutanga kuderedza zvingabvira.Tarisa pamusoro pezvinhu uye ona kuti inorema sei.Izvi zvinofanira kukubvumira kugovera zvinhu muzvikamu zvakafara zvakadai se carbon kana low alloy iron materials,stainless simbi kana nickel alloys apo unodawo nzvimbo inokosha kune alloys. uchapupu hwokuti chikamu chacho chakanga chakashongedzwa panguva yekugadzirwa kwepakutanga?Kana zvakadaro, ichi chiratidzo chakanaka chekugadzirisa zvinhu.Pane humbowo hupi hupi hupi hupi hupi hunoratidza kuti weld kugadziriswa kwave kuedzwa?Kana yakapfuura solder kugadzirisa yakundikana, iyo mureza mutsvuku inokuudza kuti uve nechokwadi chezvauri kushandisa usati waedza kugadzirisa patsva.
Kana uri kushandira chidimbu chemidziyo, unogona kudana mugadziri wepakutanga kuti abvunze kuti chii chakashandiswa.Zvimwe zvinhu zvinowanzogadzirwa kubva kune chimwe chinhu.Somuenzaniso, machira ealuminium anowanzo kugadzirwa achishandisa giredhi 6061.Kuita tsvakurudzo pamusoro pezvinhu zvinowanzo shandiswa kugadzira zvinhu zvinosungirirwa zvinogona kukubatsira kuderedza zvingasarudzwa zvako.
Sezvo uchishanda muchitoro chemuchina, unofanira kukwanisa kuwana ruzivo rwakanyanya kunaka pamusoro pezvinhu kubva kuna makanika.Kana vari kugadzira chinhu chitsva, mugadziri anogona kuziva chaizvo kuti chii.Vanogona kukupa ruzivo rwakanaka pamusoro pechigadzirwa chacho zvichienderana nemaitiro ayo ekugadzirisa.Unofanira kukwanisa kufungidzira kuoma kwesimbi zvichienderana nemitengo yezvokudya uye kumhanya kunoshandiswa panguva yekugadzira machipisi. inogona kunge iri yemahara-yekucheka giredhi iyo inowanzoitika kune inopisa kutsemuka kana yakasungwa.
Spark kuyedzwa kwesimbi uye simbi yakakandwa inogona kukupa zano rakashata rekuti ingani kabhoni iyo zvinhu zvine.Chemical spot yekuongorora inogona zvakare kuona kuvepo kweiyo chaiyo alloying zvinhu.
Kuongororwa kwemakemikari kuchapa humwe ruzivo rwakanakisisa kuti ubatsire kuziva zvikwereti zvezvinhu.Muzviitiko zvakawanda, unogona kutumira machining chips kubva kune zvinyorwa zvekuongorora.Kana pasina machining madota, kana zvichibvira, bvisa chidimbu chiduku chezvinyorwa zvekuongorora - inenge 1 inch.square.Mazhinji ekuongorora ma laboratory anopa simbi yekuongorora kemikari isingasviki $200 muzviitiko zvakawanda.
Chinonyanya kukosha, kana iwe uchida kugadzirisa zvakachengeteka uye zvekugara kwenguva refu, zvakakosha kushandisa imwe nguva uye mari shoma kuti uwane pfungwa yakanaka yezvipi zvekushandisa zvauchave welding.
