Ukwethulwa kweNozzle
Ama-nozzles avame ukusetshenziselwa ukushisela. Enqubweni yesevisi yezobuchwepheshe edlule, sithole ukuthi ukukhubazeka kokushisela kuvame ukwenzeka ngenxa yokusetshenziswa okungafanele kwemibhobho. Ukukhetha impahla ye-nozzle efanele, usayizi kanye nohlobo kungasiza ukunciphisa isikhathi sokuphumula, izindleko eziphansi kanye nokuthuthukisa ikhwalithi yokushisela kanye nokukhiqiza.
Iqhaza lombhobho ukuqondisa igesi eyisivikelo echibini elincibilikisiwe nokuvikela ichibi elincibilikisiwe ekungcoleni. Ukukhetha umlomo wombhobho kungaqinisekisa ukuthi igesi enezinga elifanele lokugeleza ingena echibini elincibilikisiwe elincibilikisiwe. Uma i-nozzle efanele ingakhethiwe, i-weldment ingaba nenani lezinkinga ezihlanganisa i-spatter ngokweqile kanye ne-porosity, okungagcina kuholele ekunciphiseni isikhathi ngenxa yokusebenza kabusha. Ngakho-ke, indlela yokukhetha i-nozzle efanele ibaluleke kakhulu. Okulandelayo kwethula ama-nozzle amaningana avamile kanye nezinzuzo zawo kanye nokubi.
umlomo wombhobho oqondile
#AmaNozzle Aqondile
Imibhobho eqondile iwuhlobo lombhobho oluvame kakhulu. Inzuzo ukuthi isetshenziswa kabanzi futhi ingasetshenziswa ezimweni ezihlukahlukene zokushisela, futhi umphumela wokuvikela igesi ungcono; okubi ukuthi ngenxa yogqinsi lwangaphambili lwembobo, ayikwazi ukungena ekujuleni lapho i-groove incane, futhi ubude obude bokuphuma kwentambo yokushisela buzokwenza ukuthi i-arc ingazinzi futhi ithinte igesi. Ngesikhathi esifanayo, ukuphela kwangaphambili okuvimbe umugqa wokubona kuzophinde kuthinte ukubhekwa kwechibi elincibilikisiwe kanye ne-arc ngesikhathi sokushisela.
#IkhoniNozzle
Ama-conical nozzles ngokuvamile asetshenziswa ekushiseleleni i-gap groove encane. Ingaphambili liyi-conical. Inzuzo yayo ukuthi ingaphambili lincane, lingangena lijule emgodini omncane, futhi kulula ukubona ukuma kwechibi elincibilikisiwe kanye ne-arc; okubi ukuthi ububanzi bangaphandle buncane, okuzothinta ukugeleza kwegesi. Ukuze kuvikelwe ikhwalithi, izimbobo zomoya zingase zenziwe ngesikhathi sokushisela, futhi i-spatter ngesikhathi sokushisela kungenzeka ukuthi ivimbele umlomo wombhobho, futhi imvamisa yokubuyisela izokwanda ngesikhathi sokushisela isikhathi eside, okuzokwandisa izindleko.
Kusukela ku-nozzle kuya kuthiphu yokuxhumana
Ubudlelwano phakathi kwe-nozzle kanye nethiphu yokuxhumana bunomthelela obalulekile kwikhwalithi ye-weld. Ithiphu yokuxhumana ingaba ngaphansi kunombozo noma ibe phezulu kunombobo. Ithiphu yokuxhumana ephansi kunombozo inganikeza ikhwalithi engcono yokuvikela igesi, kodwa ngesikhathi esifanayo izofinyeza ubude bokuphuma kwentambo yokushisela, okwenza kube nzima ngethoshi lokushisela ukungena emseleni. Ngokuphambene, ithiphu yokuxhumana ephakeme kunombozo ingcono ukufinyelela endaweni ekhawulelwe noma i-bevel, kodwa ikhwalithi yokuvikela igesi izoba mbi.
Ngakho-ke, opharetha welding udinga ukukhetha umlomo wombhobho ofaneleka kakhudlwana ngemva kokukala izinzuzo kanye nebubi.
