Yuav ua li cas Weld 304 Stainless hlau tsis muaj kab rov tav?

Thaum vuam 504 stainless hlau, kom tsim nyog xaiv vuam, thiab kev tswj cov txheej txheem yog tsim nyog kom tsis txhob tawg, tshwj xeeb tshaj yog kub thiab txias tawg. Ntawm no yog qee cov lus qhia tseem ceeb thiab cov hau kev los pab koj kom tsis txhob tawg thaum vuam ua ntej 24 stainless hlau:

1. Xaiv cov khoom siv vuam

Cov Khoom Siv Ua Si: Siv cov tub lim hlau uas phim rau cov xaim hluav taws xob, tuaj yeem zam cov xaim hlau los ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob.

Tsis txhob zam cov ntsiab lus carbon ntau: Xaiv cov hlau roj carbon ntau ntawm 304 stainless hlau ntawm vuam kev pheej hmoo thaum lub sij hawm vuam thiab txo qhov tshwm sim ntawm cov kab nrib hoom.

2. Tswj Vuam ROURD CEEV

Vuam parameter tswj: Tswj qhov tam sim no, vuam ceev, thiab voltage thaum lub sij hawm vuam kom tsis txhob muaj kev kub ntxhov dhau los. Cov kev tawm hws ntau dhau tuaj yeem ua rau overheating ntawm cov khoom siv hauv paus thiab nce txoj kev pheej hmoo ntawm cov kub kub.

Ntau txheej txheem vuam faib khoom: Tsis txhob vuam tuab welds ib zaug, thiab tswj cov cua sov-cuam tshuam nrog ntau txheej ib los ntawm ib qho los txo cov cua sov kev ntxhov siab.

3. Preheating thiab tom qab kev kho cua sov
Preheating: rau tuab 304 stainless 304 stainless hlau, muaj mob preheating (feem ntau 150}}}} degree) tuaj yeem ua, tshwj xeeb yog rau cov phiaj tuab ntau dua 6 hli. Preheating pab kom daws qhov kub nyuab siab lub sij hawm vuam.

Tom qab kev kho cua sov: Tom qab vuam, tsim nyog tom ntej kev kho mob yuav tsum tau ua, tshwj xeeb yog rau kev tiv thaiv cov khaub thuas tawg. Kev Txias Txias Tom Qab Vuam kuj pab txo qis kev ntxhov siab ntawm kev ntxhov siab.

4. Argon tiv thaiv thaum lub sij hawm vuam
Siv cov kev tiv thaiv cov roj ntau heev: siv 100% Argon li kev thaiv cov roj tuaj yeem tiv thaiv oxidation nyob rau hauv thaj chaw weld thiab txo cov poweridation los ntawm kev sib tw ntawm cov oxide zaj duab xis.

Kev tiv thaiv vuam thaiv: Tswj cov dej ntws zoo thiab thaj chaw vuam tsis muaj kuab paug los ntawm cov av volatilization thiab kev tsim cov kab nrib pleb.

5. Tsim nyog vuam ua ntu zus
Pib vuam los ntawm qhov sib tw thinner kom tsis txhob muaj kev sib tw ntau dhau los ntawm qee qhov, yog li txo cov kev ntxhov siab tshwm sim los ntawm kev sib txawv ntau.

Symmetrical vuam: Symmetrical vuam (piv txwv li vuam los ntawm ob tog tib lub sijhawm) thiab txo qhov tshwm sim ntawm cov kab nrib pleb.

6. Kev tswj kev nyuaj siab tswj hwm
Tsim nyog fixture kho: thaum lub vuam txheej txheem, kom paub meej tias cov workpiece yog tsau kom tsis txhob muaj kev ntxhov siab thiab tawg ua los ntawm kev ua haujlwm ntawm workal ntawm vuam.

Tsis txhob haus dej ntau dhau los yog ua kom txias sai: tsis txhob txias hlau loj dua tom qab vuam. Txias txias heev yuav ua rau muaj qhov sib txawv loj hauv qhov chaw vuam thiab nce kev pheej hmoo ntawm cov kab nrib pleb.

7. Qhov tsim nyog vuam ib puag ncig
Zam kev hnyav cua nrawm: zam cua kom tsis txhob muaj zog lossis cua ntws thaum lub sijhawm kub thiab txias rau qhov kub thiab txias hauv qhov kev pheej hmoo.

Tsis txhob muaj vuam nyob hauv qhov chaw kub tsawg: vuam nyob rau hauv tsawg ib puag ncig ib puag ncig tsawg dua ib puag ncig kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo thiab cov kab nrib pleb. Yog tias ua tau, qhov kub ambient yuav nce lossis preheated tsim nyog.

8. Post-Weld Tu
Tshem cov vuam slag: Tom qab vuam slag thiab oxides tsim los ntawm vuam yuav tsum tau muab tshem tawm hauv lub sijhawm kom tsis txhob muaj kev phom sij ntawm kev ntxhov siab hauv Weld.
