1. theem hlau
Txoj kev ua tiav theem yog ib qho ntawm cov txheej txheem tseem ceeb los sib txawv ntawm cov kav hlau sib koom ua ke thiabcov kav hlau tsis muaj seamless. Kev vuam hlau electro-thee siab ntawm cov kav hlau tsis ntxiv cov khoom siv vuam, yog li qhov vuam pem hauv ntej ntawm cov kav hlau welded yog nqaim heev. Yog tias txoj kev sib tsoo thiab tom qab ntawd siv stewing, cov seam tsis tuaj yeem pom tseeb. Kev sib koom ua ke hluav taws xob Yang thee siab ua tiav yam tsis muaj kev kho cua sov, uas yuav ua rau cov qauv seam txawv ntawm cov khoom siv kav hlau niam txiv. Thaum pom cov ferrite thiab Wigmansite, cov hlau hauv paus thiab cov qauv thaj tsam vuam, koj tuaj yeem txheeb xyuas cov kav hlau welded thiab cov kav hlau seamless kom raug.
2. Txoj kev xeb
Hauv cov txheej txheem ntawm kev siv txoj kev xeb kom paub qhov txawv ntawm cov kav hlau welded thiabcov kav hlau tsis muaj seamless, cov seams ntawm cov yeeb nkab steel welded uas tau ua tiav lawm yuav tsum tau polished. Tom qab kev sib tsoo tiav lawm, cov cim ntawm kev sib tsoo yuav tsum pom, thiab tom qab ntawd cov ntsej muag kawg yuav tsum tau polished nrog sandpaper ntawm qhov welds. Thiab siv 5% nitric acid cawv kua los kho qhov ntsej muag kawg. Yog tias pom tseeb qhov vuam tshwm sim, nws tuaj yeem ua pov thawj tias cov yeeb nkab steel yog cov yeeb nkab steel welded.
3. Sib txawv cov kav hlau welded thiab cov kav hlau seamless raws li cov txheej txheem
Thaum sib txawv ntawm cov kav hlau welded thiab cov kav hlau seamless raws li cov txheej txheem tsim khoom, cov kav hlau welded yog tsim los ntawm cov txheej txheem zoo li txias dov thiab extrusion, uas cuam tshuam nrog cov txheej txheem vuam., Tsis tas li ntawd, cov kav hlau arc welded siab, qis zaus thiab cov txheej txheem yeeb nkab welded tsis kam yog siv los Thaum vuam, cov yeeb nkab kauv vuam thiab cov yeeb nkab ncaj seam vuam yuav raug tsim, uas yuav tsim cov kav hlau puag ncig, cov kav hlau square, cov kav hlau oval, cov kav hlau triangular, cov kav hlau hexagonal, cov kav hlau zoo li qhiav, cov kav hlau octagonal, thiab cov nyuaj dua. Cov Yeeb Nkab Hlau.
4. Faib cov kav hlau welded thiab cov kav hlau seamless raws li lawv siv
Cov kav hlau uas vuam tau muaj lub zog khoov thiab torsional siab dua thiab muaj peev xwm thauj khoom ntau dua, yog li lawv feem ntau siv dav hauv kev tsim cov khoom siv kho tshuab. Piv txwv li, cov kav dej tho roj, cov ncej tsav tsheb, cov thav tsheb kauj vab, thiab cov hlau scaffolding siv hauv kev tsim kho yog ua los ntawm cov kav hlau vuam. Txawm li cas los xij, cov kav hlau seamless tuaj yeem siv ua cov kav dej rau kev thauj cov kua vim tias lawv muaj qhov seem hollow thiab yog cov hlau ntev uas tsis muaj seams nyob ib puag ncig lawv.
