Stainless hlau cov khoom welded tom qab cov tsos ntawm ntau qhov tsis xws luag

Stainless hlau raws liRau nws lub microstructure tuaj yeem muab faib ua tsib pawg: martensitic, martenitic, ustenitic, ferrite thiab nag lossis daus ua rau tawv tawv. Anustenitic Stainless hlau feem ntau yog tswj hwm kom dawb huv ntawm cov chav sov, thiab qee qhov me me ntawm ferrite, thiab cov me me ntawm ferrite pab tiv thaiv kev tawg thermal. Anustenitic Stainless hlau vim tias muaj kev lag luam weldability zoo, hauv kev lag luam tshuaj lom neeg, cov roj av roj thiab lwm yam kev lag luam muaj ntau siv.

Anustenitic Stainless Hlau muaj qhov zoo weldability, tab sis thaum cov txheej txheem vuam lossis cov khoom siv vuam tsis muaj tseeb, cov khoom siv hauv qab no, kev nyuaj siab corrosion, kev ntxhov siab corrosion, thermal tawg.
Raws li cov cwj pwm vuam ntawm cov yam ntxwv ntawm cov hlau tsis xeb, txhawm rau kom ntseeg tau tias qhov zoo ntawm kev sib koom tes, cov txheej txheem vuam hauv qab no yuav tsum tau siv:

1. Kev npaj ua ntej ua ntej. Nws yog ib qho tsim nyog kom tshem tawm txhua yam kev paug uas yuav carbonize tus weld hlau. Vuam Bevel thiab thaj chaw vuam yuav tsum yog de-greased thiab de-watered nrog acetone lossis dej cawv ua ntej vuam. Carbon Hlau Txhuam txhuam yuav tsum tsis txhob siv los ntxuav bevel thiab weld chaw. Slag thiab xeb tshem tawm yuav tsum sib tsoo cov log, stainless hlau hlau txhuam.

2. Yuav tsum muab cov electrodes yuav tsum muab cia rau hauv lub tsev rau khoom huv huv. Thaum siv lub vuam pas nrig yuav tsum muab tso rau hauv vuam qws lub tog raj kheej, tsis ncaj qha kov lub vuam food flux tawv nqaij nrog koj txhais tes.

3. Vuam nyias phaj thiab tsawg dua constrained stainless hlau weldments, koj tuaj yeem xaiv cov oxium oxide hom flux-daim tawv ntoo vuam pas nrig. Vim tias Arc ntawm no electrode yog ruaj khov, thiab Weld zoo nkauj zoo li tus kheej.

4. Rau qhov ntsug thiab ntsug vuam txoj hauj lwm, calcium oxide flux pob zeb cored hluav taws xob yuav tsum tau siv. Nws slag solidification sai dua, cov melted weld hlau tuaj yeem ua ib txoj haujlwm txhawb nqa.

5. Cov roj av tiv thaiv vuam thiab submerged arc Tsis siv neeg vuam, cov ntsiab lus chromium tsis siv neeg ntau dua li cov txheej txheem vuam ntawm alloying cov ntsiab ntawm kev kub hnyiab.

6. Nyob rau hauv cov txheej txheem vuam, lub weldment yuav tsum khaws cia ntawm qhov tsis muaj qhov kub qis, nyiam dua li 150 ℃.Stainless hlauTawv phaj vuam, txhawm rau ua kom nrawm txias txias, tuaj yeem txau los ntawm cov cua hauv Weld lossis cov pa hluav taws xob yuav tsum xyuam xim kom huv, txhawm rau tiv thaiv cov pa hluav taws xob tsis huv ntawm lub chaw weld.

7. Vim yog lub stainless hlau tsis kam tus nqi yog qhov loj dua, tab sis hais tias lub zog vuam yog qhov nrawm nrawm thiab yuav ua rau muaj kev tsis ncaj ncees thiab yuag thiab lwm yam tsis xws luag. Los ntawm kev ua kom muaj kev cuam tshuam corrosion tsis kam ntawm cov kev txiav txim siab ntawm cov vuam me me, kom tiv thaiv cov vuam cua sov me, kom tiv thaiv kev kub ntxhov ntawm welded kub-cuam tshuam cheeb tsam.

8. Nqaim vuam txoj kev siv tshuab yuav tsum tau siv rau hauv kev lag luam tshuab, sim tsis txhob viav vias rod

9. Cov hlau tsis muaj roj Daim yeeb yaj kiab no mus rau theem sib txawv tshwm sim, feem ntau oxidized hlau tebchaw. Nws plays lub luag haujlwm ntawm cov hlau thiab corrosion media kiag li sib cais los ntawm kev tiv thaiv cov hlau thiab cov hlau tsis muaj zog los ua kom lub luag haujlwm ntawm kev tiv thaiv corrosion.
