Vuam duplex 2205 rau 316 stainless hlau yuav tsum tau ua tib zoo xav txog cov txheej txheem vuam, muab cov hlau xaiv, thiab cov txheej txheem vuam kom zoo los xyuas kom muaj kev sib koom ua ke muaj zog thiab corrosion-resistant. Ntawm no yog cov kauj ruam dav dav thiab kev txiav txim siab rau welding ob stainless hlau alloys:
Vuam Duplex 2205 rau 316 Stainless hlau txheej txheem
1. Filler Hlau Xaiv:
Xaiv cov hlau muab tub lim uas haum rau vuamwb 2205rau316 stainless hlau. Feem ntau siv cov hlau muab tub lim muaj xws li duplex stainless hlau muab tub lim (piv txwv li, ER2209) lossis nickel-based muab tub lim hlau (xws li ERNiCrMo-3).
2. Kev xaiv cov txheej txheem vuam:
Cov txheej txheem welding feem ntau rau kev koom ua keDuplex 2205 rau 316 stainless hlausuav nrog roj tungsten arc vuam (GTAW lossis TIG), roj hlau arc vuam (GMAW lossis MIG), thiab tiv thaiv hlau arc vuam (SMAW lossis welding).
Gas tungsten arc vuam (TIG) feem ntau nyiam rau nws cov precision thiab tswj, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov tseem ceeb.
3. Kev sib koom ua ke:
Ua ib qho kev sib koom ua ke uas tso cai rau kev nkag mus thiab fusion. koj yuav tsum siv ib qho ntawm peb lub ntsiab kev sib koom ua ke - pob qij txha, pob qij txha, lossis cov pob qij txha. Ib qho bevel lossis V-groove sib koom feem ntau pom zoo. Xyuas kom haum haum thiab ua kom zoo ntawm qhov sib koom ua ke los txhawb kev sib koom tes weld hlaws.
4. Base Hlau Npaj:
Ntxuav ob lubwb 2205thiab316 stainless hlaunto kom huv si tshem tawm tej yam kab mob, oxides, los yog roj. Siv cov txhuam hniav stainless hlau los yog sib tsoo lub log rau stainless hlau kom tsis txhob muaj kab mob sib kis los ntawm lwm yam hlau.
5. Kev siv vuam:
Tuav qhov ntsuas kub ntawm qhov sib txawv hauv qhov kev teev tseg kom tsis txhob muaj cua sov ntau dhau, uas tuaj yeem ua rau degradation ntawm cov khoom siv.
Siv cov khoom siv hluav taws xob tsawg kom txo tau qhov kev pheej hmoo ntawm kev hnov mob thiab tswj kev tiv thaiv corrosion ntawm duplex stainless hlau.
Rov qab purging nrog cov roj inert (xws li argon) yuav tsim nyog los tiv thaiv oxidation nyob rau sab nraum qab ntawm lub vuam.
6. Kev kho tom qab Weld:
Tom qab vuam, ua kev kho cua sov tom qab vuam (PWHT) yog tias xav tau los ntawm cov khoom siv tshwj xeeb lossis daim ntawv thov. Ua kom zoo tu thiab passivation los txhim kho corrosion kuj.
7. Kev kuaj thiab tshuaj xyuas:
Ua kev kuaj tsis muaj kev puas tsuaj (xws li, kuaj ultrasonic, kuaj hluav taws xob) kom paub meej qhov zoo ntawm cov vuam. Kev tshuaj xyuas qhov muag thiab kev tshuaj ntsuam dye penetrant kuj tseem muaj txiaj ntsig rau kev kuaj xyuas qhov tsis xws luag.
