I-submerged arc welding (SAW), njengoba igama libonisa, iqhutshwa ngaphansi kwesendlalelo sokuzivikela noma ingubo yokuguquguquka.Njengoba i-arc ihlale imbozwe ubukhulu be-flux, iqeda noma yimiphi imisebe ekhothameni eveziwe kanye nesidingo sezikrini zokushisela.Ngokuhlukahluka okubili kwenqubo, okuzenzakalelayo kanye ne-semi-automatic, kungenye yezinqubo zokushisela ezisetshenziswa kakhulu embonini yenqubo.I-Wenzhou Tianyu Electronic Co., Ltd., engomunye wabahlinzeki bezintambo zokushisela ezingaphansi kwamanzi abangaphansi kwamanzi e-China, ibonisa isimiso nokusetshenziswa kokushisela okungaphansi kwe-arc.Ake sibabone ukuthi bayini:
Inqubo:
Ngokuhambisana nokushisela kwe-MIG, i-SAW iphinde isebenzisa indlela yokwenza i-arc phakathi kwejoyinti le-weld kanye nentambo ye-electrode engenalutho eqhubekayo.Ungqimba oluncane lwe-flux ne-slag lusetshenziselwa ukukhiqiza izingxube zegesi ezivikelayo kanye nokwengeza ama-alloys adingekayo echibini lokushisela, ngokulandelana.Njengoba i-weld iqhubeka, intambo ye-electrode ikhishwa ngenani elifanayo lokusetshenziswa futhi ukugeleza okweqile kukhishwa ngesistimu ye-vacuum ukuze igaywe kabusha.Ngaphandle kokuvikela imisebe, izendlalelo ze-flux nazo zinenzuzo enkulu ekugwemeni ukulahlekelwa ukushisa.Ukusebenza okuhle kakhulu kokushisa kwale nqubo, okungaba ngu-60%, kubangelwa yilezi zendlalelo eziguquguqukayo.Futhi inqubo ye-SAW ayinayo nhlobo yokufafaza futhi ayidingi inqubo yokukhipha umusi.
Inqubo yokusebenza:
Njenganoma iyiphi enye inqubo yokushisela, ikhwalithi yamajoyinti okushisela amayelana nokujula kokungena, ukwakheka kanye nokwakheka kwamakhemikhali ensimbi yokushisela efakiwe ngokuvamile kulawulwa amapharamitha wokushisela afana namanje, i-arc voltage, isilinganiso sokuphakelwa kwe-weld wire, kanye nesivinini sokuhamba sokushisela.Enye yezingqinamba (Yebo izindlela ezikhona zokubhekana nazo) ukuthi i-welder ayikwazi ukubheka i-weld pool ngakho-ke ikhwalithi yomthombo incike ngokuphelele kumingcele yokusebenza.
Amapharamitha okucubungula:
Njengoba kushiwo ngaphambili, kuphela ngemingcele yenqubo, futhi i-welder iphelelisa i-weld joint.Isibonelo, enqubweni ezenzakalelayo, usayizi wentambo nokuguquguquka okusetshenziswa okufanele uhlobo oluvamile, ukujiya kwento, nosayizi womsebenzi kudlala indima ebalulekile ekunqumeni izinga lokumiswa kanye nokubunjwa kobuhlalu.
Intambo:
Kuye ngesidingo sezinga lokubeka kanye nesivinini sokuhamba izintambo ezilandelayo zingakhethwa
·Twin-wire
·Izintambo eziningi
·Intambo yeshubhu
·Metal powder ukwengeza
·Intambo eyodwa enokwengezwa okushisayo
·Intambo eyodwa enokwengezwa okubandayo
I-Flux:
Ingxube eyimbudumbudu yama-oxide ezakhi eziningana ezifana ne-manganese, i-titanium, i-calcium, i-magnesium, i-silicon, i-aluminium, ne-calcium fluoride isetshenziswa kabanzi njenge-flux ku-SAW.Ngokuvamile, inhlanganisela ikhethwa ngendlela yokuthi inikeza izakhiwo ezihlosiwe zemishini lapho ihlanganisa nocingo lwe-welding.Kufanele futhi kuqashelwe ukuthi ukwakheka kwalawa ma-fluxes kudlala indima ebalulekile ku-voltage ye-arc yokusebenza kanye nemingcele yamanje.Ngokusekelwe kwimfuneko yokushisela, ngokuyinhloko izinhlobo ezimbili zama-fluxes, eziboshiwe nezihlanganisiwe zisetshenziswa kule nqubo.
Isebenzisa:
Yonke indlela yokushisela inesethi yayo yezinhlelo zokusebenza, ezivame ukudlulana ngenxa yesilinganiso somnotho kanye nemfuneko yekhwalithi.
Nakuba i-SAW ingase isetshenziswe kahle kakhulu kuwo womabili amalunga ezinqe (longitudinal kanye ne-circumferential) namajoyinti e-fillet, inemikhawulo embalwa emincane.Ngenxa ye-fluidity ye-weld pool, i-slag esimweni esincibilikisiwe kanye nongqimba oluvulekile lwe-flux, amalunga e-butt ahlala enziwa endaweni eyisicaba, futhi ngakolunye uhlangothi, amalunga e-fillet enziwa kuzo zonke izikhundla - flat, enezingqimba, futhi mpo.
Kumele kuqashelwe ukuthi inqobo nje uma izinqubo ezifanele kanye nokukhethwa kwemingcele yamalungiselelo ahlangene kwenziwa, i-SAW ingenziwa ngempumelelo ngempahla yanoma yikuphi ukushuba.
Ingatshalwa kahle ezinsimbini zekhabhoni, izinsimbi ezingagqwali nezinsimbi zengxubevange ephansi kanye nama-alloys angewona ayoni kanye nezinto zokwakha, inqobo nje uma kusetshenziswa ikhodi ye-ASME yezinhlanganisela eziphakanyisiwe zocingo kanye ne-flux.
I-SAW ithola indawo ehlala njalo ezimbonini zemishini esindayo kanye nezimboni zokwakha imikhumbi yezingxenye ezinkulu zokushisela, amapayipi amakhulu obubanzi, kanye nemikhumbi yokucubungula.
Ngokusetshenziswa okuphezulu kakhulu kocingo lwe-electrode kanye namathuba okuzenzekelayo okufinyeleleka, i-SAW ihlale ingenye yenqubo yokushisela efunwa kakhulu embonini yokukhiqiza.
