Tooj liab thiab nws cov hlau tau siv dav hauv kev tsim, tshwj xeeb hauv kev lag luam hluav taws xob thiab kav dej. Tooj liab yog tus coj hluav taws xob zoo heev thiab muaj lub siab tiv thaiv xeb thiab hnav. Cov peev txheej tshwj xeeb no tseem muaj cov kev cov nyom. Ua haujlwm nrog tooj liab, tshwj xeeb tshaj yog vuam tooj liab, xav tau nws tus kheej cov txuj ci tshwj xeeb. Ua ntej ua haujlwm nrog tooj liab, kawm paub daws nws kom nyab xeeb los ntawm kev ua raws kev tiv thaiv kom raug, txheeb xyuas cov hlau nplaum thiab tuab.
Cov kauj ruam
Ntu 1 ntawm 3: Ua Raws Li Kev Nyab Xeeb Kom Ruaj Ntseg
Kauj Ruam 1. Hnav cov iav tiv thaiv kom raug
Thaum twg los xij qhov chaw vuam siv, koj yuav tsum tsis txhob siv cov iav tiv thaiv kom raug. Cov tsom iav kev nyab xeeb, txawm tias nyob hauv lub kaus mom hlau, yuav tsum tau hnav. Lub kaus mom hlau txuas yog tej zaum qhov tseem ceeb tshaj plaws ntawm cov cuab yeej siv kev nyab xeeb vim tias nws muab kev tiv thaiv los ntawm txhua qhov ua rau koj ob lub qhov muag thiab tawv nqaij. Nws tseem tiv thaiv los ntawm ultraviolet rays uas tuaj yeem ua rau koj lub zeem muag puas.
- Lub tsho txuas yuav tiv thaiv koj los ntawm hluav taws kub thiab hluav taws xob arc.
- Hnab looj tes hnyav, nplaim taws tiv taus yuav tsum tau hnav los tiv thaiv caj npab thiab txhais tes los ntawm kev kub hnyiab thiab khawb. Xaiv cov khoom xws li tawv tawv kuj tseem yuav pab tiv thaiv hluav taws xob.
- Tsis txhob hnov qab tiv thaiv koj txhais taw nrog hnyav, khau tawv. Muaj tus tiv thaiv metatarsal hla cov hlua tuaj yeem tiv thaiv koj lub pob taws thiab ko taw sab saud los ntawm cov khoom poob.
Kauj Ruam 2. Ua haujlwm hauv thaj chaw uas muaj cua nkag tau zoo
Vuam tuaj yeem tso tawm cov pa phem. Nco ntsoov nco ntsoov tias muaj qhov tso pa tawm txaus, tshwj xeeb tshaj yog nyob rau thaj chaw uas raug kaw. Khaws cov pa tawm ze ntawm lub arc thaum hloov lub lim dej ntau kom cov pa tawm mus rau qhov tsawg kawg nkaus.
- Yog ua tau, siv rab phom tshem tawm cov pa taws. Yog tias koj tab tom siv rab phom txuas ib nrab tsis siv neeg, cov cuab yeej siv ntxiv tuaj yeem siv txhawm rau txhawm rau cov pa taws mus rau sab.
- Lub tshuab nqus pa uas pom zoo yuav tsum tau siv tas li nyob rau thaj tsam uas muaj kev tiv thaiv koj lub ntsws los ntawm cov pa.
Kauj Ruam 3. Tsis txhob kov qhov hluav taws xob nyob
Hluav taws xob ua rau tib neeg tuag txhua xyoo. Nco ntsoov hnav khau looj plab hlaub thiab tsis txhob hnav hnab looj tes nrog qhov. Vuam cov cav tov yuav tsum tau ua hauv paus kom raug, thiab cov khoom siv yuav tsum muab tua thaum tsis siv.
Txhawm rau pab tiv thaiv koj tus kheej ntxiv, ib txwm hloov kho qhov chaw raws sijhawm thiab tsuas yog txuas hauv qhov chaw qhuav. Qhov no suav nrog hnav khaub ncaws qhuav
Kauj Ruam 4. Ua kom ceev faj ntxiv
Txhawm rau ua kom ceev faj ntxiv, xav txog qhov chaw ntawm koj cov thooj voos kheej kheej roj. Lawv yuav tsum nyob deb ntawm cov arcs thiab cov cua sov ntau dhau, nrog rau txuas mus rau qhov chaw ruaj khov kom tiv thaiv kom tsis txhob poob. Cov thooj voos kheej kheej yuav tsum tsis txhob muab pov tseg kom tiv thaiv hluav taws xob.
Nco ntsoov: Tsis muaj leej twg khuv xim qhov khoom siv tua hluav taws. Muaj lub tshuab tua hluav taws tuaj yeem cawm koj lossis koj tsev neeg ntawm kev tuag
Ntu 2 ntawm 3: Xaiv Tooj
Kauj Ruam 1. Tsis txhob qias neeg, tus neeg pleev xim, lossis pleev xim hlau ua ntej
Thaum vuam, tsuas yog siv cov hlau huv xwb. Tsis txhob txhuam cov khoom uas tau pleev xim los yog plated yav tas los. Cov hlau no tuaj yeem tso pa ntau dhau. Yog tias koj paub tias hlau tau nyob rau hauv kev sib cuag nrog cov khoom phom sij, tsis txhob txhuam tshwj tsis yog tias lawv tau raug ntxuav kom raug. Cov khoom phom sij tuaj yeem ua rau muaj kev phom sij rau lub neej thiab tso pa ntau dhau.
Yog tias koj yuav tsum tau txhuam cov xim pleev xim lossis plated tooj liab, saib xyuas qhov cua. Siv koj lub tshuab ua pa thiab txuas rau ntawm qhov chaw qhib
Kauj Ruam 2. Xaiv tooj liab kom raug
Thaum vuam tooj liab, sim siv tsis muaj oxygen lossis P-deoxidized. Cov tooj liab tsis muaj oxygen yuav tso cai rau tooj liab kom khaws cov xim tooj liab qub tom qab vuam, los ntawm kev tiv thaiv oxidation. Cov hlau no feem ntau muaj tsawg dua 0.02% cov pa. P-deoxidized tooj liab muaj cov pa tsawg tab sis zoo li muaj txog li 0.05% phosphorus thiab 0.05% arsenic, uas tuaj yeem tso pa tawm. Cov tooj liab tsis muaj oxygen yog feem ntau muaj thiab npaj tau tooj liab tau yooj yim.
Kauj Ruam 3. Zam cov hlau nplaum
Thaum cov hlau tooj liab tuaj yeem txuas tau, txhua cov hlau yuav txuas sib txawv ntawm lwm qhov. Kev tsis huv tuaj yeem ua rau muaj kev sib txawv sib txawv ntawm kev nthuav dav cua sov, kev ua kom sov sov, lossis kev siv hluav taws xob. Cov tooj liab tooj liab yuav tsum tsuas yog siv los ntawm cov kws paub ntau dua.
Piv txwv li, saib tooj liab-zinc alloy. Zinc txo qhov weldability hauv tooj liab. Nws kuj tseem muaj qhov kub npau npau qis ua rau muaj cov pa lom uas tuaj yeem tsim tawm thaum siv vuam
Ntu 3 ntawm 3: Vuam tooj liab
Kauj Ruam 1. Siv qhov sib piv roj kom tsim nyog
Nyob ntawm seb koj tab tom siv TIG (tungsten inert gas) lossis MIG (hlau inert gas), thiab tuab ntawm koj tooj liab, koj yuav tsum tau kho qhov sib piv ntawm koj cov roj thiab qhov kub. Raws li txoj cai dav dav ntawm tus ntiv tes xoo, tooj liab hauv qab 2 hli yuav tsum muaj roj av argon thiab nce mus txog 160 A. Yog tias tooj liab tau tuab dua, koj yuav tsum tau kho cov roj thiab amp los ntawm kev siv helium thiab nce lub amp. Saib hauv online lossis tus kws muab khoom siv phau ntawv los txiav txim siab qhov sib piv zoo tshaj plaws rau koj cov tooj liab.
Yog tias qhov vuam tsis ua haujlwm tau zoo, sim siv 100% cov roj helium. Nws muaj lub zog siab dua piv rau Argon, uas tso cai rau kom sov ntau dua rau koj cov tooj liab
Kauj Ruam 2. Preheat tooj liab
Txij li tooj liab muaj cov cua sov ua kom sov, ua kom sov siab thiab ua kom sov yog qhov tsim nyog ntawm cov tuab ntau dua 0.01 (2 mm). Kev ntsuas cua sov ib txwm ntsuas hauv qib thiab tuaj yeem nyob qhov twg los ntawm 50 degrees Fahrenheit txog 752 degrees Fahrenheit (10 degrees Celsius-400 Celsius). Txhawm rau kom sov, yooj yim ntxig koj cov tooj liab rau hauv lub cub tawg kom txog thaum pom qhov ntsuas kub tau nce.
Preheating tso cai rau cov hlau kom txias qeeb tom qab vuam uas ua haujlwm los tsim cov hlau txuas zoo. Qhov no kuj txo qhov kev pheej hmoo ntawm kev tawg
Kauj Ruam 3. Pib lub arc kom tau lub pas dej
Thaum koj lub iav kev nyab xeeb nyob ntawm thiab koj tau npaj mus, pib lub arc. Tuav lub arc khov kho rau 2-3 vib nas this kom txog thaum lub pas dej tshwm. Thaum vuam nrog tooj liab, lub arc yuav tsum yog kwv yees li 70 degrees rau tooj liab.
Ib qho arc yog txoj kab tua hluav taws xob uas tsim los ntawm cov hluav taws xob thiab cov khoom koj tab tom siv, tooj liab
Kauj Ruam 4. Ntxiv cov muab tub lim rau hauv lub pas dej
Sai li lub pas dej tau tshwm sim, maj mam siv me me ntawm cov muab tub lim los ntawm cov kab hlau txhawm rau txhawm rau txhuam cov hlau ua ke. Thov cov muab tub lim los ntawm kev maj mam soj ntsuam nws mus rau hauv paj npleg raws li arc txuas cov tooj liab ua ke. Tus muab tub lim yuav ua kua thiab sib tov nrog ob lub tooj liab, pab cov hlau txuas ua ke.
Koj xaiv cov pas nrig yuav nyob ntawm seb hom vuam koj tab tom ua, txawm li cas los xij, nws yuav tsum yog tooj liab lossis tooj liab tooj liab
Kauj Ruam 5. Tsiv nrawm
Ntev dua koj lub pas dej tam sim no, ntau lub sijhawm tooj liab yuav tsum tau oxidize. Qhov no tuaj yeem tiv thaiv kev txhuam huv, yog li txav nrawm kom tau txais cov vuam tiav.
Kauj Ruam 6. Tso tooj liab kom txias
Kev txias txias nrawm dhau tuaj yeem txhais tau tias koj cov weld yuav tawg lossis tawg. Kev ua kom txias txias yog pab los ntawm kev ua kom sov tooj liab. Tso cov tooj liab tuaj rau qhov kub siab ua ntej vuam yuav ua kom sov sov txuas ntxiv. Yog tias vuam sab hauv tsev, nws yog qhov pom zoo kom cia lub weld cua txias yog tias nws tau preheated.
- Thaum vuam hauv qhov txias txias, koj tuaj yeem tiv thaiv koj cov tooj liab uas tau txuas tshiab los tiv thaiv nws los ntawm kev tawg. Txoj hauv kev yooj yim tshaj plaws kom txias txias yog npog cov tooj liab nrog daim pam fiberglass. Lwm txoj hauv kev yog teeb cov xuab zeb nyob ib ncig ntawm tooj liab los pab tiv thaiv kom tsis txhob tshav kub.
- Tsis txhob txaws dej los yog dej khov rau ntawm qhov txuas. Yog tias koj tsis muaj sijhawm ua siab ntev tos kom cua sov maj mam dhau mus, tsis txhob txhuam txhua.
