Ua raws li kev loj hlob sai ntawm cov kab txaij zoo sib txuas thiab kev txhim kho hluav taws xob welded, cov hom hluav taws xob txuas ntxiv, thiab nws tau hloov cov hlau tsis huv hauv ntau qhov kev lag luam. Xaws lub raj. Hauv cov txheej txheem ntau lawm ntawm welded kav, lub phiajcim Weld tuaj yeem hais tau tias muaj teeb meem tseem ceeb heev.
Ntau dhau weld seam qhov siab ntawm 316L stainless hlau muaj ntau yam zais zais, raws li hauv qab no:
(1) Kev ntxhov siab corrosion cov kab nrib pleb yog qhov tshwm sim ntawm Weld ntiv taw
Tus yuam sij rau kev ntxhov siab ntawm pob tw pob qij txha yog tsim los ntawm cov kev ntxhov siab hauv vuam
Qhov ntev ntawm kev ntxhov siab Performance index yog weld qhov siab H, qhov sib tshuam lub kaum -Gle θ ntawm Weld ntiv taw thiab lub kaum kev sib tw Semi-warp r. Qhov nce ntawm cov vuam qhov siab h nce lub kaum -Gre θ, thiab txo qis ntawm tus nqi yuav nce kev ntxhov siab ntsuas.
Qhov ntau dua qhov kev txhawb nqa ntawm Weld, qhov hnyav dua qhov kev ntxhov siab qib, tab sis lub zog compressive ntawm taub qab vuam yuav tsawg. Tom qab vuam, pluav qhov siab tshaj, yog tias nws siab dua lub pob tw wandd, txo qis kev ntxhov siab. Qee lub sij hawm nws tuaj yeem nce lub zog compressive ntawm taub qab vuam. Tus Weld sab nraud muaj qhov chaw seem loj, uas yuav ua rau raug mob lub raj tom qab lub siab nthuav dav.
Thaum txoj kev ncaj arc wrded yeeb nkab tau nthuav dav hauv qab lub siab, cov leeg khi hlau nplaum yog qhwv raws li sab nraud ntawm phab ntsa thiab tsis muaj cov yeeb nkab hauv phab ntsa sab hauv thiab cov yeeb nkab sab hauv. Yog li ntawd, yog hais tias qhov kev txhawb nqa ntawm Weld loj dhau lawm, thaum txoj kab uas hla dhau los ntawm Weld yog nquag yog 'ntawm ob sab ntawm Weld loj.
Txawm li cas los xij, kev paub ua haujlwm tau muaj pov thawj tias thaum sab nraud weld reasculated yog siv thaum 2 hli lossis tsawg dua, nws tsis yooj yim, nws tsis yooj yim dua 'thaum lub siab nthuav dav. Cov yeeb nkab hom tsis yooj yim rau kev txom nyem kev puas tsuaj. Qhov no yog vim hais tias qhov kev txhawb nqa ntawm Weld sab nraud yog me me, thiab kev cuam tshuam shear siab los ntawm pob tw weld kuj tseem me me. Yog tias hom kev ntxhov siab no yog nyob rau hauv ntau ntawm ductile deformation, tom qab tsis tuaj yeem, ib qho kev sib zog, thiab cov yeeb nkab dej yuav rov qab ua.
(2) Sab hauv Weld Seam muaj qhov tseem ceeb tshaj qhov siab, uas nce lub zog thiab lub zog kev puas tsuaj ntawm cov khoom thauj.
Yog hais tias sab nraud ntawm arc welded yeeb nkab rau kev thauj mus los tsis yog coam muaj ntau cov khoom siv los ntawm kev thauj mus los tseem loj, uas yuav ua rau muaj hluav taws xob noj ntawm kev thauj mus los.
(3) Cov hlau loj mus rau cov tuab loj loj yog qhov loj, uas tsis muaj qhov tsis zoo los tiv thaiv corrosion.
Yog tias Epoxy Laminated iav daim ntaub yog siv rau kev tiv thaiv kab corrosion thaum ua haujlwm, qhov siab ntxiv ntawm sab nraud Weld Seam yuav ua rau nias khov kho ntawm Weld ntiv taw. Tsis tas li ntawd, ntau dua lub vuam sib dhos thiab ntau dua cov txheej txheem tiv thaiv xeb yog suav nrog cov txheej txheem weld, uas nce tus nqi tiv thaiv corrosion.
Piv nrog sab hauv scraper hom sab hauv Weld Tshem Tawm Khoom, Hangao Tech (Seko Machinery) 'S Huab cua txias sab hauv weld flottening cov khoom siv tsawg dua khawb ntawm sab hauv phab ntsa ntawm cov yeeb nkab steel hlau. Nws lub hauv paus ntsiab lus ua haujlwm yog siv cov built-in sib cuam tshuam nrog lub rolling rolling 30 zaug
Yog tias koj muaj cov teeb meem zoo sib xws, thov sab laj. Peb zoo siab heev los teb rau koj.
