Zeziphi iindlela eziphambili zokusika kwiityhubhu ezixande?

Ezi ndlela zilandelayo zokusika ezintlanu zeiityhubhu ezixandeziyaziswa:
(1) Umatshini wokusika umbhobho
Umatshini wokusika umbhobho unezixhobo ezilula, utyalo-mali oluncinci, kwaye lusetyenziswa ngokubanzi.Ezinye zazo zikwanalo nomsebenzi wokuchamfer kunye nokulayisha okuzenzekelayo kunye nokukhulula kunye nezixhobo ezidibeneyo.Umatshini wokusika umbhobho sisixhobo esiqhelekileyo esisetyenziswe kwisikwere kunye noxande lombhobho wokugqiba umgca wokuvelisa;
(2) Isarha yombhobho
Inokwahlulwa ibe isarha yombhobho, isarha yebhendi kunye nesarha yesetyhula.Isarha yombhobho inokunqumla iityhubhu ezininzi zesikwere kwimiqolo ngexesha, ngamandla aphumayo aphezulu, kodwa isakhiwo sesixhobo simdaka kwaye utyalo-mali luphezulu;Iisarha zebhendi kunye neesarha zesetyhula zinamandla okuvelisa aphantsi kunye notyalo-mali oluncinci.Isarha setyhula ifanelekile ukusika iibhubhu ezixande kunye needayamitha zangaphandle ezincinci, ngelixa i-band saw ifanelekile ukusika iibhubhu ezixande ezinobubanzi obukhulu bangaphandle;
(3) Umatshini wokusarha
Umatshini wokusarha ubonakaliswe ngokusikwa ngokucocekileyo kunye ne-welding efanelekileyo ngexesha lokwakha.Isiphako kukuba amandla aphantsi kakhulu, oko kukuthi, acotha kakhulu;
(4) Ukuvala isixhobo somatshini
Amandla okuplaga aphantsi kakhulu, kwaye asetyenziswa ngokubanzi kwisampulu yetyhubhu yesikwere kunye nokulungiswa kwesampulu;
(5) Ukuvaleka komlilo
Ukusika amadangatye kubandakanya ukusika i-oxygen, ukusika i-hydrogen oksijini kunye nokusika i-plasma.Le ndlela yokusika ifaneleke ngakumbi ukusika imibhobho yentsimbi engenamthungo kunye nedayamitha yombhobho omkhulu ngakumbi kunye nodonga lombhobho olongezelelweyo.Xa ukusika i-plasma, isantya sokusika sikhawuleza.Ngenxa yokushisa okuphezulu ngexesha lokusika i-flame, kukho indawo echaphazelekayo yokushisa kufuphi ne-cuttings kunye ne-square tube end surface ayigudi.
Imibhobho yesikwere kunye noxande yimibhobho emile okwesikwere.Izinto ezininzi zinokwenza imibhobho yesikwere kunye nexande.Zisetyenziselwa nayiphi na injongo kunye nalapho zisetyenziselwa khona.Uninzi lwemibhobho yesikweri kunye noxande yimibhobho yentsimbi, ubukhulu becala yesakhiwo, ukuhombisa kunye nolwakhiwo.
Umbhobho wesikwere ligama lombhobho wesikwere, oko kukuthi, umbhobho wentsimbi onobude obulinganayo becala.Igqitywe kwintsimbi yentsimbi emva konyango lwenkqubo.Ngokuqhelekileyo, intsimbi ye-strip ikhutshwe, ihlanganiswe, igobile, idityaniswe ukuze yenze umbhobho ojikelezayo, ifakwe kwipayipi yesikwere, kwaye emva koko inqunywe ubude obufunekayo.Ngokubanzi amaqhekeza angama-50 ngepakethe nganye.
