Maitiro eWeld Stainless Simbi: Complete Guide

Stainless simbi chinhu chinoshandiswa zvakanyanya mumaindasitiri nekuda kwekuramba kwecorrosion, simba, uye chitarisiko chakachena. Nekudaro, welding simbi isina tsvina inoda chaiwo matekiniki uye matanho ekuchengetedza kuve nechokwadi chemhando uye kuvimbika kwechimiro. Gwaro iri rinokufambisa iwe kuburikidza nekutanga maitiro ekuisa simbi isina tsvina, nzira dzakanakisa, uye matipi ekudzivirira zvinowanzoitika.

Nei Welding Stainless Simbi Yakasiyana

Simbi isina tsvina yakasiyana nekabhoni simbi uye aruminiyamu kana zvasvika pakunama. Yayo yakakwira chromium uye nickel yemukati inoita kuti iwedzere kusimba mukuora, asi zvakare inonzwisisa kupisa. Welding isina kufanira inogona kukonzera warping, carbide precipitation, kana kurasikirwa kwekupokana.

Kusarudza iyo chaiyo maitiro uye yekuzadza zvinhu kwakakosha kuchengetedza kutendeseka kweiyo welded joint uye kuve nechokwadi kuti chikamu chinochengeta zvimiro zvayo zvisina tsvina.

Mhando Dzakajairika dzeStainless Simbi yeWelding

Usati wapinza, zvakakosha kuona giredhi resimbi isina simbi yauri kushanda nayo:

• Austenitic (semuenzaniso, 304, 316):Yakanyanya kusungirirwa, yakanakisa corrosion resistance

• Ferritic (semuenzaniso, 430):Mutengo wakaderera, weldability shoma

• Martensitic (semuenzaniso, 410):Zvakaoma asi zviri nyore kutsemuka

• Duplex (semuenzaniso, 2205):Yakasimba uye isingadziviriri, asi inoda kudzorwa welding maitiro

At sakysteel, tinopa zvinhu zvakasiyana-siyana zvesimbi isina tsvina-kusanganisira 304, 316, uye duplex grade-yakagadzirira kugadzirwa uye welding.

Yakanakisa Welding Nzira dzeStainless Simbi

Kune akati wandei nzira dzewelding dzakakodzera simbi isina tsvina. Sarudzo yako inoenderana nekukora, mashandisirwo, uye kuwanikwa kwemidziyo.

1. TIG Welding (GTAW)

Tungsten Inert Gasi (TIG) welding ndiyo nzira yakanyatsojeka. Inopa ma welds akachena, akasimba ane spatter shoma.

Zvakanakira:Mashizha matete asina tsvina uye aesthetics akachena
Kudzivirira gasi:100% Argon kana Argon / Helium musanganiswa
Filler tsvimbo:Inofanirwa kuenderana negiredhi resimbi (semuenzaniso,ER308Lnezve304)

2. MIG Welding (GMAW)

MIG welding inokurumidza uye iri nyore kudzidza kupfuura TIG, asi inogona kunge isina kuchena kana kutsanangurwa.

Zvakanakira:Zvikamu zvakakora uye kugadzirwa kwakakura
Kudzivirira gasi:Argon ine CO₂ kana okisijeni yekugadzikana kwearc zvirinani
Waya:Shandisa simbi isina tsvina (semuenzaniso, ER316L,ER308)

3. Stick Welding (SMAW)

Stick welding inonyanya kuregerera panzvimbo ine tsvina uye mumamiriro ekunze.

Zvakanakira:Basa rekuchengetedza nekugadzirisa
Electrodes: E308L, E309L, kana E316L zvichienderana nesimbi yepasi

Kugadzirira Mazano Usati Welding

Kugadzirira kwakakodzera kwakakosha pakuwana yakachena, isina kukanganisa weld:

• Chenesa pamusoro:Bvisa mafuta, ngura, tsvina, uye oxide layers

• Shandisa zvishandiso zvakatsaurirwa:Dzivisa kusvibiswa nekabhoni simbi maturusi

• Tack welds:Shandisa tack welds kubata zvikamu munzvimbo uye kuderedza kukanganisa

• Kucheneswa shure:Kune pombi kana welding yechubhu, kuchenesa kumashure neinert gasi kunogona kudzivirira oxidation pasi peiyo weld.

Kudzivisa Zvakajairwa Welding Defects

Dzimwe dzenyaya dzinowanzoitika kana welding simbi isina tsvina dzinosanganisira:

• Kutsemuka:Kazhinji nekuda kwekupisa kwakanyanya kana zvisiri izvo zvekuzadza zvinhu

• Kukanganisa:Inokonzerwa nekupisa kwakanyanya uye kusagadzirisa zvakanaka

• Corrosion pane weld zone:Nekuda kwekutadza kudzivirira kana kurasikirwa kwechromium panguva yewelding

• Shuga (oxidation):Kana isina kuchengetedzwa zvakanaka, mukati meweld inogona kuoxidize

Kuti udzivise izvi, shandisa inodzorwa kupisa kwekuisa, kugadzirisa gasi kudzivirira, uye post-weld yekuchenesa painoda.

Post-Weld Kucheneswa uye Passivation

Mushure mekugadzira, simbi isina tsvina inowanzoda kucheneswa kudzoreredza kusagadzikana kwekuora:

• Pickling:Kushandisa mhinduro yeasidhi kubvisa kupisa tint uye oxide layer

• Passivation:Inokwidziridza yakasikwa chromium oxide layer yekudzivirira kunaka kwekuora

• Mechanical polishing:Inotsvedza uye inovhenekera pamusoro pekushandisa zvehutsanana

sakysteelinokurudzira kugara uchiongorora zvinodiwa pamusoro pepamusoro zvichienderana nenharaunda-kunyanya pakudya-giredhi kana kushandiswa kwemugungwa.

Pfungwa dzekupedzisira

Welding simbi isina tsvina inogona kunge yakaoma kupfuura mamwe simbi, asi neruzivo rwakakwana, maturusi, uye kugadzirira, unogona kuwana akasimba, asingaite ngura majoini anogara kwemakore. Kunyangwe iwe uri kuvaka midziyo yekumanikidza, midziyo yechikafu, kana zvimiro zvemukati, kunzwisisa maitiro ekushongedza kwakakosha.

At sakysteel, hatingope zvemhando yepamusoro simbi isina simbi, mapaipi, uye masheets — tinotsigirawo maitiro ako ekugadzira neruzivo rwehunyanzvi uye nemhando yechigadzirwa inowirirana. Bata nesu nhasi kuti uwane rumwe ruzivo kana kuti uwane kurudziro yezvinhu zvakagadzirirwa kune yako welding chirongwa.
