Vuam 2205 Stainless hlau rau 304:
1. Xaiv txoj kev vuam tsim nyog
Cov txheej txheem welding feem ntau rauwelding 2205 stainless hlaurau 304 suav nrog TIG (Tungsten Inert Gas) vuam, MIG (Hlau Inert Gas) vuam, thiab arc vuam. TIG welding feem ntau yog siv rau lub pob tw vuam thiab kaum vuam, thaum MIG vuam yog tsim rau kev kub ceev ntau lawm vuam. Arc vuam siv tau rau cov phaj tuab.
2. Xaiv cov khoom siv vuam zoo
Xaiv qhov raug vuam hlau los yog electrode yog qhov tseem ceeb rau kev ua tiav cov khoom siv vuam zoo. Thaum twgvuam 2205rau 304 stainless hlau, nws tau pom zoo kom siv cov khoom siv vuam nrog cov khoom sib xws kom ntseeg tau tias muaj kev sib raug zoo nrog cov ntaub ntawv hauv paus. Cov khoom siv welding feem ntau muaj xws li:
- Vuam Hlau: Rau TIG vuam, ER2209 lossis cov xov hlau zoo sib xws raug pom zoo, raws li lawv phim cov ntsiab lus ntawm2205 stainless hlau tubing. Rau MIG vuam, ER2209 kuj yog ib qho kev xaiv.
- Vuam Electrode: Thaum xaiv cov electrodes rau arc vuam, xyuas kom lawv muaj pes tsawg leeg sib phim cov ntaub ntawv uas tau welded. Common electrodes muaj xws li AWS A5.4 E2209-16.
3. Cov txheej txheem ua haujlwm vuam
Thaum ua haujlwm vuam, ua raws li cov txheej txheem thiab cov kev xav tau no:
- Cov Nto huv: Ua ntej vuam, xyuas kom cov chaw raug ntxuav kom tshem tawm cov roj, oxides, thiab lwm yam kab mob kom ntseeg tau tias vuam zoo.
- Tswj Kub: Ob leegswb 2205thiab 304 stainless hlau yog rhiab heev rau overheating, yog li nws yog ib qho tseem ceeb los tswj qhov kub thiab txias hauv qhov chaw vuam kom tsis txhob muaj kev ntxhov siab ntau dhau thiab cov hlau degradation.
- Siv Cov Khoom Siv Vuam Zoo: Kho cov vuam tsis xws li tam sim no, qhov hluav taws xob, thiab vuam ceev raws li cov kev xaiv vuam thiab cov ntaub ntawv los xyuas kom meej qhov zoo vuam tsim thiab kev ua tau zoo.
4. Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb
Tom qab vuam tiav lawm, kev tswj xyuas qhov tsim nyog thiab kev tshuaj xyuas yog ib kauj ruam tseem ceeb hauv kev ua kom ntseeg tau qhov zoo ntawm qhov sib koom ua ke. Siv cov txheej txheem tsis muaj kev puas tsuaj thiab kev puas tsuaj los ntsuas qhov kev ncaj ncees thiab kev ua haujlwm ntawm kev sib koom ua ke los xyuas kom meej tias nws ua tau raws li cov qauv thiab cov kev xav tau.
Nkag siab txog alloy 2205 thiab 304 Cov yam ntxwv ntawm cov khoom
Ua ntej vuam, nws yog ib qho tseem ceeb kom nkag siab txog cov yam ntxwv ntawm cov ntaub ntawv uas koj ua haujlwm nrog.Duplex UNS S32205 stainless hlaupaub txog nws cov kev tiv thaiv corrosion thiab siab zog, muaj cov ntsiab lus xws li chromium, npib tsib xee, thiab molybdenum, muab kev tiv thaiv corrosion zoo heev thiab kev ntxhov siab corrosion cracking kuj. Lub caij no, 304 stainless hlau yeeb nkab yog ib qho kev siv stainless hlau alloy paub rau nws cov corrosion kuj thiab machinability.
