Inqubo yokushisela i-arc engaphansi kwamanzi iyisinqumo esihle kunazo zonke emikhakheni ebalulekile yokufakwa kwamapayipi, imikhumbi yokucindezela kanye namathangi, ukukhiqizwa kwamathrekhi kanye nokwakhiwa okukhulu.Inefomu yocingo olulodwa olulula, isakhiwo sezintambo ezimbili, uchungechunge lwesakhiwo sezintambo ezimbili kanye nesakhiwo sezintambo eziningi.
Inqubo yokushisela i-arc engaphansi kwamanzi ingazuzisa abasebenzisi ezinhlelweni eziningi zokushisela, kusukela ekukhuleni komkhiqizo kuya ezimeni zokusebenza ezithuthukisiwe kuya kukhwalithi engaguquki nokunye okwengeziwe.Izitshalo zokwenziwa kwensimbi ezicabangela ukwenza izinguquko enqubweni yokushisela i-arc engaphansi kwamanzi kufanele zicabange ngezinzuzo eziningi ezingatholakala kule nqubo.
Ulwazi oluyisisekelo lwe-arc welding engaphansi kwamanzi
Inqubo yokushisela i-arc engaphansi kwamanzi ifanele izidingo ezisindayo zokufakwa kwezimboni zamapayipi, imikhumbi yokucindezela kanye namathangi, ukwakhiwa kwesitimela, ukwakhiwa okunzima/ukumba.Ilungele izimboni ezidinga ukukhiqiza okuphezulu, ikakhulukazi lezo ezibandakanya ukushiselwa kwezinto eziwugqinsi kakhulu, ezingazuza kakhulu enqubweni yokushisela ye-arc engaphansi kwamanzi.
Izinga layo eliphezulu lokubeka imali kanye nesivinini sohambo kungaba nomthelela omkhulu ekukhiqizeni kwabasebenzi, ukusebenza kahle kanye nezindleko zokukhiqiza, okungenye yezinzuzo ezibalulekile zenqubo yokushisela i-arc engaphansi kwamanzi.
Izinzuzo ezengeziwe zifaka: ama-weld anokwakheka kwamakhemikhali okuhle kakhulu kanye nezakhiwo zemishini, ukubonakala kwe-arc okuncane kanye nentuthu yokushisela ephansi, ukunethezeka kwendawo yokusebenza okuthuthukisiwe, kanye nokuma okuhle kwe-weld kanye nomugqa wozwane.
I-arc welding engaphansi kwamanzi iyindlela yokuphakela intambo esebenzisa i-granular flux ukuhlukanisa i-arc emoyeni.Njengoba igama liphakamisa, i-arc ingcwatshwa ku-flux, okusho ukuthi lapho imingcele isethiwe, i-arc ayibonakali ngokugeleza kwesendlalelo esilandelayo se-flux.
Intambo ilokhu iphakelwa ithoshi elihamba eduze nendawo yokushisela.Ukushisa kwe-arc kuncibilikisa ingxenye yocingo, ingxenye ye-flux kanye nesisekelo sempahla ukuze kwakhiwe ichibi elincibilikisiwe, elijiyayo libe i-weld embozwe ungqimba lwe-slag yokushisela.
Ububanzi bezinto zokushisela yi-1/16 “-3/4”, okungaba ukushisela ukungena okungu-100% nge-single pass welding, uma ukushuba kodonga kunganqunyelwe, kungaba ukushisela okudlula okuningi, futhi kwenziwe okufanele. ukukhethwa kwangaphambili kokwelashwa kwe-weld, bese ukhetha inhlanganisela efanele ye-wire flux.
Ukukhetha i-flux nentambo
Ukukhetha i-flux efanele kanye nocingo lwenqubo ethile yokushisela i-arc engaphansi kwamanzi kubalulekile ukuze kuzuzwe imiphumela engcono kakhulu ngaleyo nqubo.Nakuba inqubo yokushisela i-arc engaphansi kwamanzi iyodwa isebenza kahle, ukukhiqiza nokusebenza kahle kungakhuliswa ngisho nangokusekelwe ocingweni kanye ne-flux esetshenzisiwe.
I-flux ayivikeli kuphela i-weld pool, kodwa futhi ifaka isandla ekuthuthukiseni izakhiwo zemishini kanye nokukhiqiza kwe-weld.Ukwakhiwa kwe-flux kunomthelela omkhulu kulezi zici, okuthinta umthamo wamanje wokuthwala nokukhululwa kwe-slag.Umthamo wamanje wokuthwala usho ukuthi kungatholakala ukusebenza kahle kwe-deposition kanye nephrofayili yekhwalithi ephezulu yokushisela.
Ukukhishwa kwe-slag kwe-flux ethile kuthinta ukukhethwa kwe-flux ngoba amanye ama-flux afaneleka kangcono kweminye imiklamo yokushisela kunabanye.
Izinketho zokukhetha i-Flux ye-arc welding engaphansi kwamanzi ihlanganisa izinhlobo ezisebenzayo nezingathathi hlangothi zokushisela.Umehluko oyisisekelo ukuthi i-flux esebenzayo ishintsha i-chemistry ye-weld, kanti i-neutral flux ayishintshi.
I-flux esebenzayo ibonakala ngokufakwa kwe-silicon ne-manganese.Lezi zakhi zisiza ukugcina amandla e-weld tensile ekufakweni kokushisa okuphezulu, zisiza ukushisela ukuhlala kubushelelezi ngesivinini esikhulu sohambo futhi kunikeze ukukhululwa okuhle kwe-slag.
Sekukonke, i-flux esebenzayo ingasiza ekunciphiseni ubungozi bekhwalithi embi yokushisela, kanye nokuhlanza okumba eqolo kwangemuva kokushisela nokusebenza kabusha.
Khumbula, nokho, ukuthi i-flux esebenzayo imvamisa ihamba phambili ekushiseleni okukodwa noma okuphindwe kabili.Ama-fluxes aphakathi nendawo angcono kuma-welds amakhulu ama-multi-pass ngoba asiza ukugwema ukwenza ama-weld aphukayo, azwela ukuqhekeka.
Kunezinketho eziningi zezintambo zokushisela i-arc engaphansi, ngayinye inezinzuzo kanye nokubi.Ezinye izintambo zenzelwe ukushiselwa ekufakweni kokushisa okuphezulu, kuyilapho ezinye ziklanyelwe ngokukhethekile ukuba zibe nama-alloys asiza ukugeleza kuhlanze i-weld.
Qaphela ukuthi izici zamakhemikhali zocingo kanye nokusebenzisana kokufakwa kokushisa kungathinta izici zemishini ze-weld.Ukukhiqiza kungabuye kuthuthukiswe kakhulu ngokugcwalisa ukukhetha kwensimbi.
Isibonelo, ukusebenzisa intambo ene-metal-core enenqubo yokushisela i-arc engaphansi kwamanzi kungakhuphula ukusebenza kahle kwe-deposition ngamaphesenti angu-15 kuya kwangu-30 uma kuqhathaniswa nokusebenzisa ucingo oluqinile, kuyilapho kuhlinzeka ngephrofayela yokungena ebanzi, engajulile.
Ngenxa yejubane layo eliphezulu lokuhamba, intambo yensimbi ene-cored iphinde yehlise okokufaka ukushisa ukuze kuncishiswe ubungozi bokuhlanekezelwa kokushisela nokusha.Uma ungabaza, thintana nomkhiqizi wensimbi yokugcwalisa ukuze unqume ukuthi iyiphi inhlanganisela yocingo ne-flux elungele uhlelo oluthile.
