Cov teeb meem thiab qhov tsis xws luag ntawm ERW steel kav yog muaj feem xyuam rau cov khoom siv raw, cov txheej txheem ntau lawm, cov txheej txheem txheej txheem, cov khoom siv thiab cov neeg ua haujlwm. Cov khoom tsis zoo uas tshwm sim hauv cov txheej txheem tsim khoom vim yog cov yam ntxwv saum toj no thiab kev txwv.
Cov khoom tsis zoo no tuaj yeem faib ua ob pawg: ib qho yog cov khoom tsis xws luag, uas yog, qhov tsis xws ntawm cov khoom nws tus kheej tsis sib haum nrog cov qauv khoom; thawj hom tsis xws luag generated thaum lub sij hawm ntau lawm txheej txheem tsis tsim cov kev cai ntawm cov khoom txheem cov khoom, tab sis kuj yog cov khoom zoo Qhov teeb meem, nws txoj kev loj hlob sib yuav inevitably ua rau cov khoom tsis xws luag. Yog li ntawd, xws li qhov tsis xws luag tsis raug tso cai hauv cov txheej txheem tsim khoom.

Cov txheej txheem tsis raug
Tsis muaj burr: burr welds. Sab nrauv burr feem ntau zoo dua thaum lub ntsuas dej ntsuas dej siab. Tab sis rau Ling, khoov, flattening xeem, weld feem ntau tawg.
Peach tip: weld ntawm tsis muaj glitches, thiab recessed nyob rau hauv lub phab ntsa, tsim lub taub hau ntawm txiv duaj, sim dej siab thaum dej nruj. Tab sis bending, flattening xeem, weld ntau cracking. Tsis pub dhau lub burr unilateral: watertight seam burr rau sab extrusion kuaj dej siab. Khoov, flattening xeem, qee zaum tawg.
Hlawv: sab nrauv ntawm cov pits me me hauv qhov vuam, vuam sparks ntau txaws, lub microstructure pom qhov me me watertight thaum ntsuas dej siab, khoov, flattening test, feem ntau yuav tsis tawg, tab sis qhov cuam tshuam ntawm kev siv thiab lub neej expectancy.
Weld tsis xws luag
Qhib: ncaj weld phaj ntug lub ntsej muag melting kab los yog cov kab tawg tsis muaj vuam, tawg ob lub ntsis raws li cov kev taw qhia weld, nthuav dav, nkag mus rau sab hauv ntawm qhov ntsuas dej siab, to.
Crack: micro-kawg tawg; sab nrauv ntawm qhov pom zoo ntawm cov kab zoo, sab hauv ntawm qhov tsis zoo, tsis muaj qhov xau hauv qhov ntsuas dej siab, tab sis thaum crushed los yog txias-tsim tawg.
Lap vuam: ob ntug dislocation nyob rau hauv vuam, scraping, tshwj tsis yog burrs tseem tuaj yeem pom qhov pom tseeb ntawm ib sab siab dua thiab tshaj phab ntsa thickness ntawm qhov tsis zoo sib txawv.
Deg tsis xws luag
Scratch: qhov dav dav yog cov axis ntawm txoj kab ncaj nraim thiab khawb, tob dua li ntawm phab ntsa tuab ntawm qhov tsis zoo ntawm qhov sib txawv ntawm cov khoom seem hauv qhov vuam ntawm ob sab ntawm cov ntsia hlau txuas txuas ntxiv. Super phab ntsa thickness ntawm qhov tsis zoo sib txawv. Khib loj qhov txhaum.
Kho mob: lub leveler kauv crushed obviously xav tias ntau tshaj phab ntsa thickness ntawm qhov tsis zoo tsis zoo ntawm - pov tseg tsis xws luag.
Pockmarked lub ntsej muag: lub raj nto ua tiav daim punctate me me pits nrog ib txoj kab uas hla ntawm txog 1 hli.
Warp: cov yeeb nkab nto warping kev sib cais ntawm ib feem thiab cov hlau substrate rau hauv daim, tsis tas mus li, spalling tsis tuaj yeem them taus.
