Ukushisela i-arc ecmerged (SAW), njengoba igama lisho, kwenziwa ngaphansi kwesendlalelo esivikelayo noma ingubo yokushisela. Njengoba i-arc ihlala imbozwe ukujiya kokushisela, isusa noma yikuphi ukushiswa okuvela kuma-arches avele kanye nesidingo sezikrini zokushisela. Ngezinhlobo ezimbili zenqubo, okuzenzakalelayo kanye ne-semi-automatic, ingenye yenqubo yokushisela esetshenziswa kabanzi embonini yenqubo. I-Wenzhou Tianyu Electronic Co., Ltd., omunye wabahlinzeki bezintambo zokushisela i-arc ecmerged abadumile eShayina, ikhombisa isimiso kanye nokusetshenziswa kokushisela i-sub-arc. Ake sibone ukuthi ziyini:
Inqubo:
Ngokufana nokushisela kwe-MIG, i-SAW isebenzisa nendlela yokwakha i-arc phakathi kwe-weld joint kanye ne-continuous bare electrode wire. Isendlalelo esincane se-flux kanye ne-slag sisetshenziselwa ukukhiqiza izingxube zegesi ezivikelayo kanye nokwengeza ama-alloy adingekayo echibini le-weld, ngokulandelana. Njengoba i-weld iqhubeka, i-electrode wire ikhishwa ngesilinganiso esifanayo sokusetshenziswa futhi i-flux eyengeziwe idonswa ngesistimu ye-vacuum ukuze isetshenziswe kabusha. Ngaphandle kokuvikela imisebe, izingqimba ze-flux nazo ziwusizo kakhulu ekugwemeni ukulahlekelwa ukushisa. Ukusebenza kahle kokushisa okuhle kwale nqubo, cishe ama-60%, kubangelwa yilezi zingqimba ze-flux. Futhi inqubo ye-SAW ayinayo nhlobo i-splitter futhi ayidingi noma iyiphi inqubo yokukhipha i-fume.
Inqubo yokusebenza:
Njenganoma iyiphi enye inqubo yokushisela, ikhwalithi yamajoyinti okushisela maqondana nokujula kokungena, ukuma kanye nokwakheka kwamakhemikhali kwensimbi yokushisela ebekwe ngokuvamile kulawulwa yimingcele yokushisela efana nogesi, i-arc voltage, izinga lokuphakelwa kwentambo yokushisela, kanye nesivinini sokuhamba kokushisela. Enye yezingqinamba (vele izindlela ziyatholakala zokuzixazulula) ukuthi ukushisela akukwazi ukubuka ichibi lokushisela ngakho-ke ikhwalithi yomthombo incike ngokuphelele kumapharamitha okusebenza.
Amapharamitha enqubo:
Njengoba kushiwo ngaphambili, kumane nje kungamapharamitha enqubo, futhi umshini wokushisela uphelelisa ijoyinti lokushisela. Isibonelo, enqubweni ezenzakalelayo, usayizi wentambo kanye nokuguquguquka okusetshenziswayo okufanele uhlobo oluvamile, ukujiya kwezinto, kanye nosayizi womsebenzi kudlala indima ebalulekile ekunqumeni izinga lokufakwa kanye nokuma kobuhlalu.
Ucingo:
Kuye ngesidingo sesilinganiso sokufakwa kanye nesivinini sokuhamba, izintambo ezilandelayo zingakhethwa
·Izintambo ezimbili
·Izintambo eziningi
·Intambo ye-Tubular
·Ukwengezwa kwempuphu yensimbi
·Intambo eyodwa enokufakwa okushisayo
·Intambo eyodwa enokufakwa okubandayo
Ukuguquguquka:
Ingxube ye-granular yama-oxide ezinto eziningana ezifana ne-manganese, i-titanium, i-calcium, i-magnesium, i-silicon, i-aluminium, kanye ne-calcium fluoride isetshenziswa kabanzi njenge-flux ku-SAW. Ngokuvamile, inhlanganisela ikhethwa ngendlela yokuthi ihlinzeka ngezakhiwo ezihlosiwe zemishini lapho ihlangana nentambo yokushisela. Kufanele futhi kuqashelwe ukuthi ukwakheka kwalezi fluxes kudlala indima ebalulekile ku-voltage ye-arc esebenzayo kanye namapharamitha wamanje. Ngokusekelwe esidingweni sokushisela, ngokuyinhloko izinhlobo ezimbili ze-fluxes, eziboshiwe kanye nezihlanganisiwe ziyasetshenziswa kule nqubo.
Ukusetshenziswa:
Indlela ngayinye yokushisela inesethi yayo yezinhlelo zokusebenza, ezivame ukuhambisana ngenxa yobukhulu bokusebenza kahle kanye nesidingo sekhwalithi.
Nakuba i-SAW ingasetshenziswa kahle kakhulu kokubili amalunga ezinqe (i-longitudinal kanye ne-circumferential) kanye namalunga e-fillet, inemikhawulo embalwa emincane. Ngenxa yokugeleza kwe-weld pool, i-slag esimweni esincibilikisiwe kanye nengqimba ekhululekile yokugeleza, amalunga ezinqe ahlala eqhutshwa endaweni eyisicaba, kanti ngakolunye uhlangothi, amalunga e-fillet enziwa kuzo zonke izikhundla - eziyisicaba, ezivundlile, kanye neziqondile.
Kufanele kuqashelwe ukuthi uma nje kwenziwa izinqubo ezifanele kanye nokukhethwa kwemingcele yokulungiselela amalunga, i-SAW ingenziwa ngempumelelo ezintweni zanoma yiluphi ubukhulu.
Ingasetshenziswa kahle kakhulu ezitsheni zekhabhoni, ezitsheni ezingagqwali kanye nasezintweni eziphansi ze-alloy kanye nezinhlayiya ezimbalwa ezingezona i-ferrous nezinto zokwakha, uma nje ikhodi ye-ASME iphakamisa ukuthi kusetshenziswa inhlanganisela yensimbi ne-flux.
I-SAW ithola indawo ehlala njalo ezimbonini zemishini esindayo kanye nasezimbonini zokwakha imikhumbi yezingxenye ezinkulu zokushisela, amapayipi amakhulu, kanye nemikhumbi yokucubungula.
Njengoba i-electrode wire isetshenziswa kakhulu futhi ikwazi ukusebenziseka kalula, i-SAW ihlala ingenye yezinqubo zokushisela ezifunwa kakhulu embonini yokukhiqiza.
