Welded kav yog ua los ntawm steel phaj los yog steel strips uas khoov thiab ces welded. Raws li daim ntawv welding seam, nws muab faib ua ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab.
Raws li lub hom phiaj, lawv tau muab faib ua feem ntau welded kav, galvanized welded kav, oxygen-blown welded kav, hlau casings, metric welded kav, cov menyuam kav, sib sib zog nqus twj tso kua mis kav, automotive kav, transformer kav, hluav taws xob welded nyias-walled kav. , hluav taws xob welded tshwj xeeb-zoo li tus kav thiab kauv welded kav.
General welded yeeb nkab: General welded yeeb nkab yog siv los thauj cov dej uas tsis tshua muaj siab. Ua los ntawm Q195A, Q215A, Q235A steel. Nws tseem tuaj yeem ua los ntawm lwm cov hlau me me uas yooj yim weldable. Cov kav hlau yuav tsum tau ua raws li kev sim xws li hydraulic siab, khoov, thiab flattening, thiab muaj qee yam yuav tsum tau ua rau qhov zoo. Feem ntau, qhov ntev ntawm tus me nyuam yog 4-10m, thiab kev xa khoom ntev ntev (lossis ntau qhov ntev) feem ntau xav tau.
Cov specifications ntawm welded kav yog qhia nyob rau hauv nominal txoj kab uas hla (millimeters los yog nti). Lub nominal txoj kab uas hla txawv ntawm qhov tseeb. Raws li cov txheej txheem phab ntsa thickness, muaj ob hom welded kav: zoo tib yam steel kav thiab thickened steel kav. Cov hauv qab no yog cov lus qhia luv luv rau kev siv ntawm ntau cov kav dej tawv tawv:
1. Feem ntau cov kav dej welded yog siv rau kev thauj mus los ntawm cov khoom siv qis qis xws li dej, roj, cua, roj, thiab cua sov.
2. Ordinary carbon steel hlau tes tsho (GB3640-88) yog cov yeeb nkab steel siv los tiv thaiv cov xov hlau thaum lub sij hawm siv hluav taws xob xws li cov tsev lag luam thiab pej xeem thiab kev teeb tsa ntawm cov tshuab thiab cov khoom siv.
3. Ncaj seam hluav taws xob welded yeeb nkab (YB242-63) yog cov yeeb nkab steel uas lub vuam seam yog sib npaug mus rau qhov ntev ntawm cov yeeb nkab steel. Feem ntau muab faib ua metric fais welded kav, hluav taws xob welded nyias-walled kav, transformer txias roj kav, thiab lwm yam.
4. Ib qho kauv submerged arc welded yeeb nkab rau kev thauj mus los ntawm cov kua dej siab (SY5036-83) yog cov kauv submerged arc welded yeeb nkab rau kev thauj mus los ntawm cov kua siab. Nws yog ua los ntawm kub-kuav los tiag steel sawb coils thiab spirally tsim ntawm qhov kub thiab txias. Nws yog welded los ntawm ob-sided submerged arc vuam. Nws yog ib qho kauv submerged arc welded yeeb nkab rau kev thauj mus los ntawm cov kua dej Sewing steel yeeb nkab. Cov kav hlau steel muaj lub zog siab-cov kabmob muaj peev xwm thiab kev ua haujlwm vuam zoo. Lawv tau dhau los ua ntau yam kev soj ntsuam thiab kev sim thiab muaj kev nyab xeeb thiab txhim khu kev qha. Cov yeeb nkab steel muaj txoj kab uas hla loj, kev thauj mus los zoo, thiab tuaj yeem txuag kev nqis peev hauv kev tso cov kav dej. Feem ntau yog siv rau cov kav dej thauj cov roj thiab cov nkev.
5. Kauv seam high-frequency welded yeeb nkab (SY5038-83) rau kev thauj mus los ntawm cov kua dej siab yog ua los ntawm kub dov steel strip coils raws li cov yeeb nkab blanks, spirally tsim ntawm qhov kub thiab txias, thiab welded los ntawm high-frequency lap welding txoj kev. Nws yog siv rau kev thauj mus los ntawm cov kua dej siab. Kauv seam high-frequency welded steel yeeb nkab. Cov kav hlau muaj lub zog siab-cov kabmob muaj peev xwm, thiab cov yas zoo, thiab yooj yim rau vuam thiab txheej txheem. Tom qab ntau yam kev soj ntsuam nruj thiab kev tshawb fawb thiab kev sim, lawv muaj kev nyab xeeb thiab txhim khu kev ntseeg siv. Cov yeeb nkab steel muaj cov kab loj loj, kev thauj mus los zoo, thiab tuaj yeem txuag kev nqis peev hauv kev tso cov kav dej. Feem ntau yog siv los tso cov kav dej thauj cov roj, cov pa roj, thiab lwm yam.
6. Kauv submerged arc welded steel yeeb nkab (SY5037-83) rau kev thauj mus los uas tsis tshua muaj siab yog ua los ntawm kub dov steel strip coils raws li cov yeeb nkab blanks thiab yog spirally tsim ntawm qhov kub thiab txias; nws yog tsim los ntawm ob-sided tsis siv neeg submerged arc vuam los yog ib sab welding. Submerged arc welded steel kav yog siv los thauj cov dej uas tsis tshua muaj siab xws li dej, roj, cua, thiab chav.
Welded kav siv tau peb txoj kev sim hardness.
