Yuav ua li cas Weld 904L stainless hlau?

Vuam ntawm 904L Stainless Hlau

Txhawm rau kom ua tau zoo thiab corrosion tsis kam ntawm welded pob qij txha, xaiv cov ntaub ntawv vuam tsim nyog tsim nyog thiab cov tswv yim yog qhov tseem ceeb.

Vuam cov ntaub ntawv

Cov Hluav Taws Xob: Ntau hom electrode hom suav nrog e {385-16 thiab e 385-17, uas muaj rau lawv haum rau vuam 904L stainless hlau.

Vuam hlau: ER385 vuam hlau kuj yog ib qho kev xaiv ib txwm muaj, muab cov kev ua tau zoo dua thiab siv roj tshuab (roj (roj tungsten arc vuam) cov txheej txheem.

904L Stainless Hlau Vuam Txheej Txheem

Preheating: Preheating ua ntej vuam pab txo kom muaj kev ntxhov siab thiab kev tsim. Lub preheating kub feem ntau yog li ntawm 150 txog 300 degree, nyob ntawm qhov tuab ntawm cov khoom siv thiab vuam cov xwm txheej.

Kev Tswj Qhov Kub Kub: Thaum ntau ntau cov vuam, qhov kev sib txuas ntawm qhov kub yuav tsum khaws cia ntawm 200 thiab 350 degree kom ntseeg tau weld zoo thiab txo qhov tawv me me hauv qhov chaw kub.

Tom qab-Weld Kev Kho Cua Sov: Tom qab Weld Kev Kho Mob Kub pab tshem tawm cov kev ntxhov siab uas muaj kev ntxhov siab thiab txhim kho cov khoom siv neeg kho hauv Weld. Cov kev sib xws suav nrog annealing thiab tempering, nrog cov tsis tseeb txiav txim los ntawm cov tuab thiab cov khoom siv ntawm welded sib koom tes.

Vuam tsis xws luag thiab tiv thaiv kev ntsuas

Tawg pleb: Kev tswj kom tsim nyog ntawm preheating thiab cuam tshuam qhov kub thiab kub, nrog rau kev zam kev ua kom txias sai, tuaj yeem pab txo qis zuj zus.

Porosity: Ua kom muaj kev ntxhua khaub ncaws huv thiab siv cov pa thaiv uas tsim nyog (xws li Argon) tuaj yeem txo cov porosity tsim.

Tsis muaj fusion: Kev tswj kom zoo ntawm vuam tam sim no thiab nrawm ua kom muaj kev lom zem puv nkaus ntawm txhua Weld Pass.
