1. Dab tsi yog "Welded yeeb nkab" txhais tau tias?
Ib hom yeeb nkab welded yog ib hom steel yeeb yog los ntawm rolling lub tiaj tus hlau phaj lossis ntawv cim (npe hu ua "sylindrical puab thiab tom qab ntawd koom nrog nws cov npoo nrog weld. Cov ntsiab lus tseem ceeb yog tsim lub raj los ntawm ib lub tiaj ntawm cov hlau los ntawm kev sib sau thiab fusing rau leeg. Qhov kev qhia no tso cai rau kev tsim cov kav dej nrog cov kab uas diameters loj thiab ntev txuas ntxiv ntev. Welded kav yog qhov tseem muaj cov khoom siv hauv niaj hnub tsim kho kom thauj cov dej, roj av, thiab cov ntawv thov txheej txheem txheej txheem.
2.What yog weld yeeb nkab?
"Weld yeeb nkab" yog qhov tseem ceeb dua lwm lo lus rau "Welded yeeb nkab." Nws yog hais txog tib yam khoom: ib qho yeeb nkab uas muaj cov kab sib tw ntev uas tau khiav raws nws qhov chaw uas cov npoo ntawm cov hlau strip tau fused ua ke. Lo lus "Weld yeeb nkab" feem ntau hais txog lub xub ntiag ntawm cov leeg no. Qhov zoo thiab kev ncaj ncees ntawm Weld yog qhov tseem ceeb rau cov yeeb nkab kev ua tau zoo thiab nws cov kev siv tsim qauv.
3.Yog li cas yog qhov sib txawv ntawm seamless thiab welded kav?
Thawj qhov sib txawv ntawm lawv cov txheej txheem tsim khoom. Lub yeeb nkab seamless yog tsim los ntawm tho lub zog, root steel billet los tsim lub raj hollow tsis muaj nqaws. Qhov no ua rau nws muaj zog dua thiab muaj zog ntau dua hauv nws txoj kev ncig, tshwj xeeb tshaj yog raws li kev kub siab. Ib txoj yeeb nkab welded, raws li tau piav, yog ua los ntawm ib tug yob thiab welded steel phaj, ua rau pom ntawm seam.
Tseem Ceeb Cov Ntsiab Lus:
* ** Lub zog: ** Seamless kav yog feem ntau muaj zog thiab ntau txhim khu kev qha rau high- qhov chaw tsis muaj zog zoo li weld seam.
* ** Tus nqi & muaj: ** Welded kav tsis kim dua los tsim thiab muaj nyob rau hauv diameters loj dua thiab ntev ntev.
* ** Phab ntsa tuab: ** Cov kav dej seamless tuaj yeem muaj cov phab ntsa zoo sib xws yuav muaj ntau yam sib txawv, thaum muaj ntau yam sib txawv nyob ze ntawm Weld thiab feem ntau yog txwv rau phab ntsa.
* ** Qhov chaw saum npoo av: ** Cov chaw sab hauv thiab sab hauv ntawm cov kav dej tsis sib xws yog feem ntau smoother tshaj weld Bead yuav tsum tau muab tshem tawm rau qee cov ntawv thov.
4.What yog qee qhov siv rau Welded Yeeb Nkab?
Welded kav yog ntau yam thiab yog siv nyob rau hauv ntau ntawm kev lag luam. Cov siv sib xws li suav nrog:
* ** Dej thiab roj thiab roj hloov chaw: ** Loj -}}} Lub qhov dej hauv cov kab hauv nroog yog cov kab ke thiab cov roj hauv kev ncua ntev dhau mus deb.
* ** Cov ntawv thov cov txheej txheem: ** Lawv tau siv dav siv hauv kev tsim kho scaffolding, thiab fencing vim lawv tus nqi- ua hauj lwm zoo thiab muaj.
* ** COV ROJ THIAB COV ROJ THIAB THAUJ MUS LOS ROJ THIAB roj, tshwj xeeb tshaj yog qhov kev txhawj xeeb ntau yog tsis yog qhov kev txhawj xeeb tseem ceeb, cov kav dej welded yog qhov dav dav.
* ** COV NEEG KHO TSHUAB THIAB SIV RAU ntau yam khoom siv tshuab, tso pa taws, thiab cov kheej kheej kheej kheej kheej.
* ** Kev siv kav dej: ** Rau qhov tsawg rau nruab nrab -}}} siab cov dej thauj mus los hauv cov nroj tsuag thiab cov vaj tse.
5. Yuav ua li cas yog ib qho yeeb nkab welded?
Cov txheej txheem vuam ua rau cov yeeb nkab cuam tshuam nrog ntau cov kauj ruam tseem ceeb thiab cov txheej txheem sib txawv. Cov hau kev feem ntau yog:
1. ** Kev tsim: ** Ib lub tiaj tus kab txaij yog tsis muaj peev xwm tiv thaiv thiab pub los ntawm cov yob uas maj mam khoov rau hauv cov duab cylindrical.
2. *** Vuam: ** Qhib cov npoo tau coj ua ke thiab welded. Ob txoj kev nthuav dav feem ntau yog:
* ** THAWJ KHWV VUAM (ERW): ** High {- zaus hluav taws xob tam sim no tau dhau los ntawm cov npoo, muab cua sov rau lawv mus rau lub xeev me me. Siab yog tom qab ntawd thov rau forge lawv ua ke tsis muaj tub lim hlau.
* ** Submerged arc vuam (pom): ** Siv rau loj- txoj hauj lwm uas hla hla. Lub ADD arc raug tsoo hauv qab daim pam ntawm Granular Flux, uas tiv thaiv tus mold weld los ntawm kev sib kis thiab tso cai rau qhov muaj zog heev weld, feem ntau nrog muab cov hlau txuas ntxiv.
3. ** Sizing thiab Shaping: ** Welded cov yeeb nkab hla dhau los los ntawm cov yob ntau kom ua tiav nws txoj kab uas hla kawg thiab kev sib tw.
4. ** Kev tshuaj xyuas thiab tshuaj xyuas: ** Weld SEAM yog qhov kev kuaj mob zoo li kev sim ultrasonic 1}} rays kom ntseeg tau tias nws yog pub tsis xws luag.
5. ** TEJ: ** Cov yeeb nkab txuas txuas tau txiav rau cov kev lag luam uas yuav tsum tau ua haujlwm ntev.
