1. Hlau theem
Txoj kev puv theem yog ib txoj hauv kev tseem ceeb kom paub qhov txawv ntawm cov kav dej sib txuas thiabseamless steel kav. High-frequency electro-coal welding ntawm steel kav tsis ntxiv vuam cov ntaub ntawv, yog li cov vuam pem hauv ntej ntawm cov welded steel yeeb nkab yog nqaim heev. Yog tias txoj kev sib tsoo thiab siv stewing, lub seam tsis tuaj yeem pom meej. Lub zog hluav taws xob Yang thee sib koom ua tiav tsis muaj kev kho cua sov, uas yuav ua rau cov qauv seam yog qhov tseem ceeb sib txawv ntawm cov yeeb nkab steel niam txiv cov khoom. Thaum cov ferrite thiab Wigmansite, lub hauv paus hlau thiab weld cheeb tsam cov qauv raug soj ntsuam, , koj tuaj yeem txheeb xyuas cov kav hlau welded thiab seamless steel kav.
2.Corrosion method
Nyob rau hauv tus txheej txheem ntawm kev siv cov txheej txheem corrosion kom paub qhov txawv ntawm welded steel kav thiabseamless steel kav, cov seams ntawm cov txheej txheem welded steel kav yuav tsum tau polished. Tom qab kev sib tsoo tiav, cov kab sib tsoo yuav tsum pom, thiab tom qab ntawd lub ntsej muag kawg yuav tsum tau polished nrog cov ntawv xuab zeb ntawm cov welds. Thiab siv 5% nitric acid cawv daws los kho lub ntsej muag kawg. Yog hais tias pom tseeb weld tshwm, nws tuaj yeem ua pov thawj tias cov yeeb nkab steel yog welded steel yeeb nkab.
3. Distinguishing welded steel kav thiab seamless steel kav raws li cov txheej txheem
Thaum sib txawv ntawm welded steel kav thiab seamless steel kav raws li cov txheej txheem tsim, welded steel kav yog tsim los ntawm cov txheej txheem xws li txias dov thiab extrusion, nrog rau cov txheej txheem welding., Tsis tas li ntawd, high-frequency, low-frequency arc welded kav thiab kuj. Cov txheej txheem welded yeeb nkab yog siv rau thaum vuam, kauv yeeb nkab vuam thiab ncaj seam yeeb nkab vuam yuav raug tsim, uas yuav tsim cov kav hlau, square steel kav, oval steel kav, daim duab peb sab steel kav, hexagonal steel kav, ginger-shaped steel kav, octagonal steel kav, thiab txawm ntau nyuaj sawv daws yuav. Cov yeeb nkab steel.
4. Muab faib welded steel kav thiab seamless steel kav raws li lawv siv
Welded steel kav muaj ntau dua dabtsi yog khoov thiab torsional zog thiab ntau dua load-bearing muaj peev xwm, yog li ntawd lawv yog feem ntau lug siv nyob rau hauv lub manufacturing ntawm txhua yam khoom. Piv txwv li, roj laum kav, tsheb tsav shafts, tsheb kauj vab ncej, thiab steel scaffolding siv nyob rau hauv kev tsim kho yog tag nrho cov ua los ntawm welded steel kav. Txawm li cas los xij, seamless steel kav yuav siv tau los ua cov kav dej rau kev thauj cov kua dej vim tias lawv muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
