Yuav Ua Li Cas Weld Stainless Hlau: Ua tiav Daim Ntawv Qhia

Stainless hlau yog cov khoom siv dav siv thoob plaws hauv kev lag luam vim nws txoj kev tiv thaiv corrosion, lub zog, thiab huv si. Txawm li cas los xij, welding stainless hlau yuav tsum muaj cov txheej txheem tshwj xeeb thiab kev ceev faj kom ntseeg tau zoo thiab kev ua haujlwm zoo. Phau ntawv qhia no yuav taug kev koj los ntawm cov hauv paus ntawm yuav ua li cas vuam stainless hlau, txoj kev zoo tshaj plaws, thiab cov lus qhia kom tsis txhob muaj teeb meem.

Yog vim li cas Vuam Stainless hlau yog txawv

Stainless hlau yog txawv ntawm carbon hlau thiab txhuas thaum nws los txog rau vuam. Nws cov ntsiab lus siab chromium thiab npib tsib xee ua rau nws tiv taus corrosion, tab sis kuj muaj ntau dua rau cov cua sov. Kev vuam tsis zoo tuaj yeem ua rau warping, carbide nag lossis daus, los yog poob ntawm corrosion kuj.

Xaiv cov txheej txheem kom raug thiab cov khoom muab tub lim yog qhov tseem ceeb kom muaj kev ncaj ncees ntawm cov welded sib koom ua ke thiab xyuas kom meej tias qhov chaw khaws nws cov khoom tsis muaj zog.

Hom Hom Stainless Hlau rau Vuam

Ua ntej welding, nws yog ib qho tseem ceeb kom paub cov qib ntawm stainless hlau koj ua hauj lwm nrog:

• Austenitic (eg, 304, 316):Feem ntau welded, zoo heev corrosion kuj

• Ferritic (eg, 430):Tus nqi qis, txwv weldability

• Martensitic (eg, 410):Nyuaj tab sis ntau dua rau kev tawg

• Duplex (piv txwv li, 2205):Muaj zog thiab corrosion-resistant, tab sis yuav tsum tau tswj cov txheej txheem vuam

At sakysteel ua, peb muab ntau yam khoom siv stainless hlau-xws li 304, 316, thiab qib duplex-npaj rau fabrication thiab vuam.

Qhov zoo tshaj plaws Vuam txoj kev rau Stainless hlau

Muaj ntau txoj kev vuam tsim nyog rau stainless hlau. Koj qhov kev xaiv nyob ntawm qhov tuab, daim ntawv thov, thiab cov khoom muaj nyob.

1. TIG Welding (GTAW)

Tungsten Inert Gas (TIG) vuam yog qhov tseeb tshaj plaws. Nws muab huv si, muaj zog welds nrog tsawg spatter.

Qhov zoo tshaj plaws rau:Nyias stainless hlau nplooj ntawv thiab huv si zoo nkauj
Tiv thaiv Gas:100% Argon lossis Argon / Helium mix
Filler pas nrig:Yuav tsum phim cov qib hlau puag (piv txwv li,TSI 308Lrau 304)

2. MIG Welding (GMAW)

MIG vuam yog nrawm dua thiab yooj yim kawm dua TIG, tab sis tej zaum yuav tsis huv lossis ntxaws.

Qhov zoo tshaj plaws rau:Thicker seem thiab loj fabrication
Tiv thaiv Gas:Argon nrog CO₂ lossis oxygen kom zoo dua arc stability
Hlau:Siv cov hlau tsis muaj hlau (xws li ER316L,TIAB SA 308)

3. Nplaum Vuam (SMAW)

Txoj hlua vuam yog ntau zam rau ntawm qhov chaw qias neeg thiab nyob rau sab nraum zoov.

Qhov zoo tshaj plaws rau:Kev tu thiab kho kev ua haujlwm
Electrodes: E308L, E309L, lossis E316L nyob ntawm lub hauv paus hlau

Cov tswv yim npaj ua ntej vuam

Kev npaj kom raug yog qhov tseem ceeb rau kev ua tiav qhov huv, tsis muaj qhov tsis xws luag:

• Ntxuav qhov saum npoo:Tshem tawm cov roj, xeb, av, thiab oxide txheej

• Siv cov cuab yeej tshwj xeeb:Tsis txhob hla kev sib kis nrog cov cuab yeej carbon steel

• Tack welds:Siv tack welds los tuav qhov chaw nyob rau hauv qhov chaw thiab txo cov distortion

• Rov qab purging:Rau cov yeeb nkab lossis raj vuam, rov qab purging nrog cov roj inert tuaj yeem tiv thaiv oxidation ntawm lub hauv qab ntawm qhov vuam.

Zam kev vuam tsis xws luag

Qee qhov teeb meem nquag tshaj plaws thaum vuam stainless hlau suav nrog:

• Kev tawg:Feem ntau vim muaj cua sov ntau dhau los yog cov khoom siv tsis raug

• Distortion:Ua los ntawm cov khoom siv hluav taws xob siab thiab cov khoom siv tsis zoo

• Corrosion ntawm weld cheeb tsam:Vim tsis raug shielding los yog poob ntawm chromium thaum vuam

• Qab Zib (oxidation):Yog tias tsis tiv thaiv kom zoo, sab hauv ntawm lub vuam tuaj yeem oxidize

Txhawm rau tiv thaiv cov no, siv cov hluav taws xob tswj hluav taws xob, kho cov pa roj kom raug, thiab tom qab vuam tu qhov xav tau.

Tom qab Weld Cleaning thiab Passivation

Tom qab welding, stainless hlau feem ntau yuav tsum tau ntxuav kom rov qab corrosion kuj:

• Pickling:Siv cov kua qaub kom tshem tawm cov cua sov thiab oxide txheej

• Passivation:Txhim kho lub ntuj chromium oxide txheej kom zoo dua corrosion kuj

• Mechanical polishing:Smooths thiab brightens saum npoo rau kev siv huv si

sakysteel uapom zoo kom ib txwm ntsuas qhov kev xav tau ntawm qhov chaw nyob ntawm qhov chaw - tshwj xeeb tshaj yog rau cov khoom noj khoom haus lossis kev siv dej hiav txwv.

Kev xav zaum kawg

Vuam stainless hlau tej zaum yuav nyuaj dua li lwm yam hlau, tab sis nrog txoj kev paub, cov cuab yeej, thiab kev npaj, koj tuaj yeem ua tiav cov pob qij txha muaj zog, corrosion-resistant uas kav ntev xyoo. Txawm hais tias koj tab tom tsim cov hlab ntsha siab, khoom noj khoom haus, lossis cov khoom siv, kev nkag siab txog cov txheej txheem vuam yog qhov tseem ceeb.

At sakysteel ua, peb tsis tsuas yog muab cov khoom zoo stainless hlau rods, kav, thiab nplooj ntawv-peb kuj txhawb koj cov txheej txheem fabrication nrog cov ntaub ntawv thiab cov khoom zoo ib yam. Tiv tauj peb hnub no kom paub meej ntxiv los yog kom tau txais cov lus pom zoo rau cov khoom siv rau koj qhov project vuam.
