Kauv Welded Yeeb Nkab Rau Cov Kab Yeeb Nkab Hluav Taws
Qhov zoo tshaj plaws ntawmkauv welded yeeb nkabyog lub peev xwm los tsim cov kav hlau ntawm ntau txoj kab uas hla los ntawm cov kab uas muaj tib qhov dav. Qhov no yog qhov zoo tshaj plaws thaum xav tau cov hlau nqaim los tsim cov kav hlau loj. Nrog rau lub peev xwm tsim khoom no, cov khoom muaj kev hloov pauv ntau tshaj plaws thiab kev ywj pheej kom tau raws li ntau yam kev xav tau ntawm ntau yam haujlwm thiab kev lag luam.
Tsis tas li ntawd xwb, qhov loj ntawm cov kav dej sib txuas ua ke yog qhov tseeb heev. Feem ntau, qhov kam rau siab ntawm txoj kab uas hla tsis pub tshaj 0.12%, ua kom ntseeg tau tias qhov loj ntawm txhua lub kav dej tsim tawm yog qhov tseeb thiab sib xws. Qib kev raug no yog qhov tseem ceeb rau cov ntawv thov uas qhov kev ncaj ncees ntawm qhov ntev yog qhov tseem ceeb.

Ntxiv rau qhov loj me meej, cov yeeb nkab vuam uas muab kauv muab kev ruaj khov zoo heev. Vim tias qhov deflection tsawg dua 1/2000, cov yeeb nkab qhia qhov kev hloov pauv tsawg kawg nkaus ntawm nws cov duab tiag tiag txawm tias nyob rau hauv kev hloov pauv siab thiab lub zog sab nraud. Qhov no ua kom ntseeg tau tias muaj kev ua haujlwm zoo thiab ua haujlwm tau zoo, ua rau cov khoom zoo tagnrho rau cov ntawv thov tseem ceeb xws li cov yeeb nkab hluav taws.
Ntxiv mus, qhov ovality ntawm cov yeeb nkab kauv welded yog tsawg dua 1%, ntxiv txhim kho nws cov khoom siv tau ntev thiab kev ntseeg siab. Qhov kev tswj ovality no yog qhov tseem ceeb rau cov ntawv thov uas cov yeeb nkab voj voog sib xws yog qhov tseem ceeb rau kev ntws dej du thiab kev ua haujlwm zoo tshaj plaws. Nrog cov yeeb nkab kauv welded, qhov zoo thiab kev ua haujlwm ntawm cov kua lossis roj xa khoom tsis raug cuam tshuam.
Qhov tseem ceeb, cov txheej txheem tsim cov yeeb nkab uas vuam ua ke no tshem tawm qhov xav tau cov txheej txheem ntsuas qhov loj thiab ncaj. Qhov no ua rau txuag tau sijhawm thiab tus nqi ntau, ua rau cov khoom lag luam pheej yig thiab ua haujlwm tau zoo. Los ntawm kev tshem tawm cov kauj ruam tsim khoom ntxiv, cov neeg siv khoom txaus siab rau lub sijhawm ua khoom luv dua thiab txo cov nqi tsim khoom, ua rau kev ua haujlwm zoo dua.
Cov yeeb nkab vuam sib txuas yog tsim tshwj xeeb raucov kav dej hluav tawsqhov twg cov kev cai nruj thiab kev ua tau zoo txhim khu kev qha yog qhov tseem ceeb. Nws qhov tseeb ntawm qhov loj me, kev ruaj khov ntawm cov qauv thiab kev tswj hwm qhov oval ua rau nws zoo tagnrho rau kev thauj dej, ua npuas dej lossis lwm yam tshuaj tua hluav taws kom tiv thaiv lub neej thiab khoom vaj khoom tsev.
Tsis tas li ntawd xwb, cov yeeb nkab uas vuam ua ke yog qhov tsim nyog rau ntau yam kev siv, suav nrog cov kav dej roj thiab roj av, cov kev txhawb nqa thiab cov haujlwm tsim kho vaj tse. Nws qhov kev hloov pauv tau yooj yim thiab kev ua tau zoo ua rau nws yog qhov kev xaiv zoo rau ntau yam lag luam uas xav tau cov yeeb nkab hlau zoo.
Hauv kev xaus lus, cov yeeb nkab vuam kauv rau cov yeeb nkab hluav taws yog cov khoom lag luam uas muaj kev ua tau zoo tshaj plaws thiab muaj txiaj ntsig zoo. Nws lub peev xwm los tsim cov yeeb nkab hlau ntawm ntau txoj kab uas hla, qhov loj me meej, kev ua haujlwm zoo heev, thiab cov txheej txheem tsim khoom txuag sijhawm ua rau nws yog qhov kev xaiv ntau yam thiab pheej yig. Txawm hais tias nws yog cov yeeb nkab hluav taws lossis lwm yam kev siv, cov yeeb nkab vuam kauv tuaj yeem muab qhov zoo thiab kev ntseeg siab kom tau raws li qhov xav tau ntawm ntau yam haujlwm thiab kev lag luam.
