Kev sib piv ntawm qhov ruaj khov ntawm riveting thiab vuam tsis tuaj yeem yooj yim dav. Nws nyob ntawm ntau yam, nrog rau cov khoom siv, cov qauv kev sib txuas, hom thauj khoom thiab ib puag ncig.
1. Kev cuam tshuam ntawm cov khoom tseem ceeb ntawm kev ruaj khov
Riveting
Rau cov khoom sib txawv, qhov ruaj khov ntawm riveting yog txawv. Thaum txuas cov ntaub ntawv hlau, xws li txhuas alloys, cov khoom xaiv ntawm rivets yog ib qho tseem ceeb heev. Yog tias rivets nrog kev sib raug zoo nrog aluminium alloys, xws li txhuas rivets, siv, kev sib txuas zoo zog tuaj yeem muab tau. Txawm li cas los xij, rau qee qhov muaj zog alloy steels, vim qhov nyuaj ntawm cov khoom, riveting yuav ua rau muaj kev ntxhov siab nyob ib ncig ntawm lub qhov rivet, cuam tshuam qhov ruaj khov ntawm kev sib txuas.
Vuam
Vuam kuj muaj qhov sib txawv adaptability rau cov ntaub ntawv. Qee cov ntaub ntawv uas muaj qhov zoo weldability, xws li cov pa roj carbon tsawg, tuaj yeem tau txais cov pob qij txha muaj zog heev tom qab vuam. Txawm li cas los xij, rau qee cov ntaub ntawv tshwj xeeb, xws li aluminium alloys, qhov tsis xws luag xws li lub qhov hws thiab cov kab nrib pleb tau yooj yim tsim thaum lub sij hawm vuam, uas yuav txo tau qhov ruaj khov ntawm cov pob qij txha welded. Tsis tas li ntawd, txoj kev sib txawv ntawm vuam kuj tseem haum rau cov khoom sib txawv. Piv txwv li, argon arc vuam yog tsim rau vuam cov ntaub ntawv xws li stainless hlau thiab txhuas alloys, thaum rau cam khwb cia hlau cov ntaub ntawv, arc vuam tej zaum yuav haum dua.
2. Cov nyhuv ntawm qhov load hom ntawm firmness
Riveting
Riveting ua tau zoo nyob rau hauv withstanding shear quab yuam. Piv txwv li, nyob rau hauv lub thav duab kev twb kev txuas ntawm railway tsheb, riveting tau zoo tiv thaiv lub shear quab yuam generated los ntawm lub tsheb thaum lub sij hawm ua hauj lwm. Txawm li cas los xij, thaum raug nro, tshwj xeeb tshaj yog rau ib qho rivet, yog tias qhov nro loj heev, lub rivet yuav raug rub tawm los yog lub qhov rivet yuav deformed, ua rau kev sib txuas tsis ua haujlwm.
Vuam
Vuam tuaj yeem tiv taus ntau hom kev thauj khoom, suav nrog kev nruj, siab thiab shear. Hauv kev tsim cov hlab ntsha siab, cov pob qij txha welded yuav tsum tau tiv thaiv lub siab hauv siab (siab load) thiab qhov hnyav ntawm lub nkoj nws tus kheej thiab lwm yam cuam tshuam (nruj thiab shear force) tib lub sijhawm. Ntev npaum li qhov vuam zoo yog qhov zoo, qhov sib txuas welded tuaj yeem hloov cov khoom no kom muaj kev nyab xeeb ntawm lub nkoj.
3. Cov nyhuv ntawm ib puag ncig ntawm kev ruaj khov
Riveting
Cov qauv kev sib txuas riveted tuaj yeem tiv thaiv kev co thiab cuam tshuam rau qee yam. Hauv kev sib txuas ntawm lub plhaub ntawm qee cov cuab yeej siv tshuab, riveting tuaj yeem tswj kev ruaj ntseg ntawm kev sib txuas hauv qab qhov kev vibration ib puag ncig tsim los ntawm kev ua haujlwm ntawm lub tshuab. Ntxiv mus, riveting tsis yooj yim cuam tshuam los ntawm ib puag ncig corrosive vim hais tias cov rivet thiab cov khoom sib txuas yog mechanically txuas, thiab txawm tias cov txheej txheej puas lawm, nws tsis yooj yim los tsim electrochemical corrosion zoo li vuam.
Vuam
Welded pob qij txha tuaj yeem cuam tshuam rau hauv qhov hnyav corrosive ib puag ncig. Piv txwv li, nyob rau hauv marine ib puag ncig, yog hais tias welded steel qauv tsis muaj zoo los tiv thaiv corrosion, electrochemical corrosion yog nquag tshwm sim nyob rau hauv lub welds, uas ua rau ib tug txo nyob rau hauv lub zog ntawm cov welded pob qij txha. Txawm li cas los xij, los ntawm kev siv cov txheej txheem vuam tsim nyog thiab kev tiv thaiv corrosion, xws li kev siv cov khoom siv vuam corrosion-resistant thiab coatings, lub zog ntawm welded pob qij txha nyob rau hauv ib puag ncig corrosive tuaj yeem txhim kho.
Hauv cov ntsiab lus, nyob rau hauv qhov tsim nyog, ob qho tib si vuam thiab riveting tuaj yeem muab kev sib txuas zoo txaus. Vuam tej zaum yuav yog ib qho kev xaiv zoo dua thaum cov high-precision, high-strength tag nrho cov qauv yuav tsum tau thiab cov khoom muaj weldability zoo; riveting tej zaum yuav ua tau zoo dua nyob rau hauv kev sib txuas uas yuav tsum tau tiv thaiv shear quab yuam, muaj ib tug tej yam kam rau kev co thiab cuam tshuam, thiab nyob rau hauv ib co nyuaj-rau-weld khoom sib txuas.
