Kev saib xyuas yuav tsum tau ua rau cov teeb meem no hauv kev ua haujlwm vuam ntawm cov kav hlau stainless welded

  Stainless hlau welded yeeb nkabyog ua los ntawm steel los yog steel sawb tom qab crimping los ntawm lub tshuab thiab tuag.Tus yuam sij rau qhov kev lees paub zoo ntawm stainless hlau welded yeeb nkab yog qhov zoo ntawm cov khoom siv raw.Yog li ntawd, tag nrho cov khoom siv raw rau hauv lub Hoobkas ua ntej siv, yuav tsum tau kuaj xyuas, suav nrog: kev kuaj pom, qhov dav thiab qhov tuab yog sib npaug;Tsis tas li ntawd, cov tshuaj lom neeg muaj pes tsawg leeg thiab tensile kuaj xyuas, tsim nyog ua ntej ntau lawm.Txawm li cas los xij, nyob rau hauv qhov tseeb zus tau tej cov stainless hlau welded yeeb nkab, feem ntau tshwm sim no los yog qhov teeb meem.Yog li, koj puas paub dab tsi yog cov teeb meem uas stainless hlau welded kav yog nquag?Dab tsi yog vim li cas rau cov teeb meem no nyob rau hauv stainless hlau welded kav?Ntawm no tus sau ua kev daws teeb meem nrog koj.

Nyob rau hauv kev lag luam vuam ntawm stainless hlau vuam yeeb nkab Hoobkas, cov teeb meem uas yuav tshwm sim yog: tsis tsim nyog vuam seam, tsis tiav vuam los yog raug hlawv los ntawm, tawg thiab pores.Yuav kom paub meej, nws yog:

1. Weld tsis tsim nyog yog vim kev xaiv tsis raug ntawm cov txheej txheem vuam tsis zoo lossis kev siv tshuab tsis zoo.Ua rau qhov siab thiab qis dav ntawm qhov vuam sib txawv, thiab tom qab ntawd ua rau cov duab ntawm cov vuam tsis zoo, lub nraub qaum ntawm cov vuam yog concave, ua rau cov vuam tsis muaj zog ntau dhau, yog li ntawd lub zog ntawm vuam yog tsis txaus.

2. Kev vuam tsis tiav lossis kub hnyiab los ntawm kev vuam tsis tiav yog vim li no: ua ntej, qhov tam sim no me dhau;Qhov thib ob, kev lag luam thev naus laus zis tsis txawj ntse, vuam ceev nrawm dhau, lub pob tw tshem tawm me me;Lub arc ntev dhau los yog arc tsis ua raws li qhov sib txuas.Yog hais tias lub vuam hlau thiab lub hauv paus hlau tsis fused ua ke los yog lub vuam hlau tsis fused hauv zos, qhov yuav tsum tau kho nyob rau hauv lub sij hawm.Qhov laj thawj ntawm kev kub hnyiab los ntawm qhov feem ntau yog vim qhov vuam tam sim no ntau dhau.Lub pas dej molten kub yog siab dhau lawm.Lub vuam hlau tsis tau ntxiv rau lub sijhawm, lub pob tw tshem tawm yog loj dhau;Vuam ceev yog qeeb heev.Cov xwm txheej no yuav ua rau ib leeg lossis txuas ntxiv perforation ntawm lub vuam, kom lub zog ntawm cov vuam tsis muaj zog, thiaj li yuav tsum tau hlawv.

3. Cov kab nrib pleb thiab qhov hws (1) Qhov teeb meem nrog lub siab zaus yog cov kab nrib pleb.Raws li qhov sib txawv ntawm cov kab nrib pleb, cov kab nrib pleb dav tuaj yeem muab faib ua cov kab nrib pleb thiab cov kab nrib pleb txias.Kub tawg tshwm sim vim kub tawg nrog oxidation xim yog tsim raws li intergranular ciam teb ntawm qhov kub ntawm cov kua hlau thaum lub sij hawm solidification los yog me ntsis qis dua cov khoom theem kab.Thaum txias tawg yog qhov txias tawg nrog cov cuab yeej transgranular, ci ntsa iab thiab tsis muaj oxidizing xim uas tshwm sim nyob rau hauv cov khoom theem transformation, los yog muaj diffused hydrogen, thiab nyob rau hauv qhov kev txiav txim ntawm ntau welding shrinkage kev nyuaj siab thaum txias.Yog tias kev siv vuam hlau tsis yog raws li tus qauv, vuam qhov kub ntawm qhov chaw nyob ntev dhau lawm, ua rau oxidation, overheating thiab loj hlob ntawm cov siv lead ua loj, cov khoom nws tus kheej yog impurities ntau dua, los yog cov khoom nws tus kheej yog ib qho yooj yim rau harden, tab sis kuj tseem yuav tawg.(2) Porosity tshwm sim vim muaj cov roj stains, oxide daim tawv nqaij thiab xeb ntawm qhov chaw vuam thiab vuam hlau, los yog vuam nyob rau hauv ib qho chaw ntub dej, los yog cov roj argon tsis muaj purity, los yog argon roj tiv thaiv tsis zoo, thiab cov molten. pas dej ua ke yog oxidized ntawm qhov kub thiab txias, txaws thiab lwm yam kev mob yog yooj yim los tsim porosity.Cov teeb meem saum toj no feem ntau tshwm sim hauv kev ua haujlwm vuam ntawm stainless hlau vuam raj manufacturers.
