Lub zog ntawm cov kauv raj feem ntau siab tshaj qhov ncaj seam welded yeeb nkab. Nws tuaj yeem siv cov yeeb nkab welded nrog ib txoj kab uas loj dua ntawm cov khoom siv billet, thiab tseem tuaj yeem siv tib qhov dav los tsim ib lub raj nrog cov kav dej sib txawv nrog cov kav dej sib txawv. Txawm li cas los xij, piv nrog tib qhov ntev ntawm tib qhov ntev, qhov ntev ntawm qhov vuam yog nce los ntawm 30 ~ 100%, thiab qhov ceev ntau lawm yog qis dua. Yog li ntawd, feem ntau ntawm cov me me-caliber welded kav yog welded nrog ncaj seams, thiab feem ntau ntawm cov loj-caliber welded kav yog feem ntau muab kauv welded. Tom qab qhov loj-diameter kauv steel yeeb nkab chaw tsim tshuaj paus, ob npoo ntawm kauv steel yeeb nkab billet tau rhuab mus rau vuam kub. Nyob rau hauv lub squeezing cov menyuam, cov hlau nplej ntau nkag mus thiab crystallized, thiab thaum kawg ib tug ruaj welded sib koom.
Lub kauv steel yeeb nkab yog welded nrog ob-sided arcs. Sab hauv welds thiab txheej welds muaj qhov siab tom qab vuam. Qhov siab ntawm qhov vuam seem ntawm cov kauv steel yeeb nkab kuj tau teev tseg los ntawm tus qauv. Dab tsi yog tus qauv ntau ntawm cov vuam seem qhov siab? Qhov tseeb, cov kev cai ntawm tus qauv kauv steel kav thiab lub teb chaws tus qauv kauv steel kav ntawm welded residual heights yog tib yam. Phab ntsa thickness tsawg dua los yog sib npaug rau 13 hli kauv steel kav. Qhov seem ntawm qhov siab ntawm sab hauv thiab sab nraud yuav tsum tsis pub tshaj 3.5 hli, thiab phab ntsa tuab yog ntau dua 13 hli. Qhov seem qhov siab yuav tsum tsis pub tshaj 4.5 mm.
Yuav ua li cas ntsuas qhov seem qhov siab ntawm welded seams ntawm kauv steel yeeb nkab? Ua ntej ntawm tag nrho cov, peb yuav tsum npaj ib tug weld los xyuas tus pas ntsuas, visually xyuas qhov tsim ntawm weld, xaiv ib tug neeg sawv cev ib feem, thiab siv lub weld los xyuas tus pas ntsuas. Kev ntsuas kev taw qhia yuav tsum ua tib yam rau lub axis ntawm kauv steel yeeb nkab. Kauv steel yeeb nkab manufacturers feem ntau tswj qhov siab ntawm welded seams ntawm 2 hli thiab 2.5 hli, vim hais tias cov kauv steel yeeb nkab welds tsim nyob rau hauv txoj kev no kuj zoo nkauj heev.
