Qhov teeb meem ntawm yellowing ntawm vuam nto nyob rau hauv lub taub qab vuam tshuab tuaj yeem yog ib qho kev txhawj xeeb rau cov welders thiab cov kws tshaj lij hauv kev lag luam vuam. Nkag siab txog qhov ua rau thiab kev daws teeb meem rau qhov teeb meem no yog qhov tseem ceeb rau kev ua kom zoo nkauj zoo nkauj thiab zoo nkauj zoo nkauj welds. Kab lus no tshawb txog cov txheej txheem zoo los daws qhov yellowing ntawm vuam qhov chaw hauv lub taub qab vuam tshuab, muab cov tswv yim daws teeb meem los daws qhov teeb meem no.
- Kev txheeb xyuas qhov ua rau: Thawj kauj ruam hauv kev daws qhov yellowing ntawm vuam qhov chaw yog txhawm rau txheeb xyuas qhov tshwm sim. Cov laj thawj muaj peev xwm rau qhov kev hloov xim no suav nrog cov khoom siv vuam tsis raug, kev sib kis, lossis muaj cov impurities hauv cov khoom siv vuam.
- Kho Vuam Parameters: Tshawb xyuas thiab kho qhov vuam tsis zoo, xws li vuam tam sim no, qhov hluav taws xob, thiab xaim pub ceev, kom ntseeg tau tias lawv tsim nyog rau daim ntawv thov vuam tshwj xeeb. Kev tswj xyuas kom zoo yuav pab ua kom huv thiab zoo ib yam welds yam tsis muaj xim.
- Xyuas kom huv huv Workpieces: Cov khoom tsis huv los yog qias neeg tuaj yeem ua rau yellowing ntawm qhov chaw vuam. Ua tib zoo ntxuav qhov chaw ntawm lub hauv paus hlau ua ntej welding kom tshem tawm cov roj, roj, lossis lwm yam kab mob uas tuaj yeem ua rau muaj xim daj.
- Siv cov khoom siv vuam zoo: xyuas kom meej tias cov khoom siv vuam zoo, nrog rau cov khoom siv hluav taws xob thiab cov xaim xaim, siv rau hauv cov txheej txheem vuam. Cov ntaub ntawv tsis zoo yuav muaj cov impurities uas ua rau cov xim tsis zoo rau ntawm qhov chaw vuam.
- Ua raws li cov khoom siv tiv thaiv zoo: Hauv cov txheej txheem uas siv cov roj thaiv kev tiv thaiv, xws li MIG lossis TIG vuam, xyuas kom muaj kev xaiv raug thiab ntws ntawm cov roj thaiv kev tiv thaiv. Kev siv cov roj shielding zoo tiv thaiv lub pas dej ua ke los ntawm atmospheric contamination, txo cov xim tsis zoo.
- Tom qab Weld Ntxuav thiab Polishing: Tom qab vuam, ua tom qab vuam tu thiab polishing kom tshem tawm cov xim tsis zoo. Cov txheej txheem no pab kho qhov zoo li ntawm weld thiab ua kom pom qhov pom kev ua tiav.
- Preheating thiab Post-Weld Thaum tshav kub kub kho (PWHT): Rau cov khoom siv tshwj xeeb thiab kev sib koom ua ke, xav txog kev ua kom sov lub hauv paus hlau ua ntej vuam thiab ua haujlwm tom qab vuam kub. Cov tswv yim no pab txo qhov kev pheej hmoo ntawm kev hloov xim thiab txhim kho tag nrho cov tsos ntawm cov vuam.
- Weld Quality Inspection: Ua ib qho kev soj ntsuam zoo ntawm qhov vuam zoo kom paub meej tias qhov teeb meem daj tau raug daws. Tshawb xyuas qhov kev ncaj ncees thiab qhov zoo ntawm qhov vuam, thiab ua qhov tsim nyog hloov kho rau cov txheej txheem vuam raws li xav tau.
Hauv kev xaus, hais txog qhov yellowing ntawm vuam qhov chaw hauv pob tw vuam tshuab suav nrog kev txheeb xyuas cov hauv paus hauv paus thiab siv cov kev daws teeb meem zoo. Kho qhov vuam tsis zoo, ua kom cov khoom ua haujlwm huv si, siv cov khoom siv vuam zoo, cov pa tiv thaiv kom zoo, tom qab vuam tu, thiab kev kho cua sov yog cov kauj ruam tseem ceeb los daws cov teeb meem tsis zoo. Los ntawm kev ntsuas kev ntsuas thiab ua tib zoo saib xyuas qhov zoo ntawm cov khoom siv vuam, cov vuam thiab cov kws tshaj lij tuaj yeem ua tiav cov welds nrog pristine tsos thiab kev ua haujlwm zoo. Ua raws li cov kev daws teeb meem no tsis yog tsuas yog txhim kho qhov zoo nkauj ntawm welds tab sis kuj tseem txhawb nqa tag nrho cov kev vam meej thiab kev ua haujlwm ntawm ntau yam kev siv vuam thiab kev lag luam.
