Yuav Ua Li Cas Flux Core Weld Stainless Steel

Stainless hlau yog ib qho tseem ceeb hauv kev lag luam xws likev tsim kho, kev ua zaub mov, tshuaj lom neeg, tsheb, thiab kev tsim kho hauv hiav txwvNws lub zog ruaj khov, tiv taus xeb, thiab ua tiav huv si ua rau nws muaj nqis heev. Txawm li cas los xij, kev vuam hlau tsis xeb feem ntau nyuaj dua piv rau cov hlau carbon vim nwskev nthuav dav thermal, kev ua haujlwm tawv, thiab kev cuam tshuam rau kev hloov pauv.

Ib txoj hauv kev siv tau los txuas cov hlau tsis xeb yogKev sib txuas ntawm cov hlau nplaum flux core arc (FCAW)Cov txheej txheem no siv cov electrode uas siv tau tas li uas muaj cov flux ntawm nws lub hauv paus, uas tsim cov roj tiv thaiv thiab slag los tiv thaiv qhov vuam ntawm kev ua qias tuaj. Hauv tsab xov xwm no, peb yuav muab cov lus qhia ntxaws ntxaws txogYuav ua li cas flux core weld stainless hlau, suav nrog cov khoom siv zoo, cov xov hlau sau, cov txheej txheem, thiab cov kev coj ua zoo tshaj plaws.

Nkag Siab Txog Kev Siv Flux Core Welding (FCAW)

Kev vuam flux core yog ib qho txheej txheem vuam semi-automatic lossis automatic arc. Nws zoo ib yam li kev vuam MIG tab sis txawv ntawm txoj kev uas qhov vuam raug tiv thaiv.

Hom Flux Core Vuam:

1. Tiv Thaiv Tus Kheej (FCAW-S):

   • Siv cov flux hauv cov hlau los tsim cov pa roj tiv thaiv.

   • Zoo tagnrho rau cov ntawv thov sab nraum zoov thiab cov chaw muaj cua hlob.

2. Tiv Thaiv Roj (FCAW-G):

   • Yuav tsum tau muaj cov roj tiv thaiv sab nraud ntxiv (xws li CO₂ lossis Ar/CO₂ sib xyaw).

   • Tsim cov vuam huv dua nrog tsawg dua spatter.

Rau kev vuam hlau tsis xeb,Cov xov hlau flux core uas tiv thaiv rojfeem ntau nyiam dua vim yog qhov zoo dua ntawm kev vuam.

Vim li cas thiaj siv Flux Core rau Stainless Steel?

• Tus Nqi Tso Siab:Tso cai rau kev vuam sai dua piv rau TIG lossis pas nrig.

• Zoo rau cov ntaub ntawv tuab:Kev nkag mus zoo heev rau cov ntu hnyav.

• Kev siv tau ntau yam:Siv tau rau hauv txoj hauj lwm tiaj tus, ntsug, thiab saum taub hau.

• Tus nqi tsim nyog:Cov nqi khoom siv qis dua piv rau TIG vuam.

• Kev Haum Sab Nraud:FCAW uas tiv thaiv tus kheej ua haujlwm hauv cov chaw uas MIG vuam yuav ua tsis tiav vim cua.

Cov Khoom Siv Xav Tau

1. Tshuab Vuam

   • Lub hwj chim hluav taws xob tas li (lub tshuab vuam MIG uas sib xws nrog cov kua dej).

   • Yuav tsum tau siv cov hlau tsis xeb uas muaj qhov loj li ntawm 0.9 hli lossis 1.2 hli.

2. Flux Core Stainless Hlau Hlau

   • Cov qib feem ntau suav nrog308L, 309L, thiab 316L cov xov hlau flux-cored, nyob ntawm seb lub hauv paus hlau.

3. Cov Roj Tiv Thaiv (rau FCAW-G)

   • Argon + CO₂ (75/25 sib xyaw) lossis CO₂ ncaj qha.

4. Cov Khoom Siv Tiv Thaiv

   • Lub kaus mom hlau vuam, hnab looj tes, lub tsho loj, thiab cov tsom iav kev nyab xeeb.

5. Cov Cuab Yeej Npaj

   • Lub tshuab sib tsoo rau kev ntxuav cov hlau puag.

   • Txhuam hlau (txhuam hlau tsis xeb kom tsis txhob muaj kuab paug).

Cov Kauj Ruam Qhia: Yuav Ua Li Cas Flux Core Weld Stainless Steel

Kauj Ruam 1: Npaj Cov Hlau Tseem Ceeb

• Ntxuav cov hlau tsis xeb kom huv si.

• Tshem tawm cov av qias neeg, roj, xim, thiab cov txheej oxide.

• Siv txhuam hlau tsis xeb kom tsis txhob muaj pa roj carbon.

Kauj Ruam 2: Xaiv Cov Hlau Flux Core Kom Yog

• Sib phim qib hlau filler nrog hom stainless hlau:

  • 308L Hlau:Rau 304 stainless hlau vuam

  • 309L Hlau:Rau kev txuas cov hlau tsis xeb rau cov hlau tsis muaj zog

  • 316L Hlau:Rau 316 stainless hlau thiab marine daim ntawv thov

Kauj Ruam 3: Xaiv Qhov Chaw Vuam

• Voltage thiab ampere nyob ntawm qhov loj ntawm cov hlau thiab cov khoom siv tuab.

• Piv txwv li: Rau 1/8 nti stainless hlau nrog 0.9 hli hlau → 18–20 volts, 150–180 amps.

Kauj Ruam 4: Siv Cov Roj Tiv Thaiv Kom Zoo (yog tias FCAW-G)

• Cov khoom sib xyaw uas nyiam:75% Argon / 25% CO₂rau cov vuam du thiab tsawg dua spatter.

• Siv tau CO₂ ncaj nraim tab sis ua rau qhov chaw ntxhib dua.

Kauj Ruam 5: Txoj Haujlwm thiab Tack Weld

• Ruaj ntseg cov workpieces siv clamps.

• Siv cov tack welds kom tsis txhob muaj kev cuam tshuam.

Kauj Ruam 6: Kev Siv Vuam

• Tswj ib qholub kaum sab xis rub (10–15°)thaum siv cov flux core uas tiv thaiv tus kheej.

• Khaws qhov ceev kom ruaj khov kom tsis txhob kub dhau.

• Rau kev vuam ntsug, siv kev nce mus rau sab saud kom nkag mus zoo dua.

Kauj Ruam 7: Tshem Tawm Slag
