Txiv ntseej qhov chaw vuam yog cov txheej txheem kev lag luam uas siv los koom nrog ob daim hlau los ntawm kev tsim kom muaj kev sib txuas ruaj khov thiab ruaj khov. Txawm li cas los xij, nws tsis yog qhov tsis tshua muaj tshwm sim rau qhov chaw vuam tig daj tom qab txheej txheem vuam. Qhov kev hloov ntawm cov xim no tuaj yeem raug ntaus nqi rau ntau yam.
- Thaum tshav kub kub:Thaum lub sij hawm vuam txheej txheem, cov hlau nto yog raug kub heev, uas yuav ua rau oxidation thiab discoloration. Thaum cov hlau kub dhau heev lawm, txheej txheej ntawm oxide tshwm rau ntawm qhov chaw, uas ua rau yellowish tint.
- Cov khoom paug:Yog hais tias cov hlau raug welded muaj impurities los yog cov kab mob, cov no tuaj yeem hnov mob nrog cov cua sov thiab tsim kom muaj xim. Cov impurities no yuav suav nrog cov roj, cov xim, lossis cov coatings uas tsis tau ntxuav kom zoo ua ntej vuam.
- Kev tiv thaiv tsis txaus:Cov txheej txheem vuam feem ntau siv cov roj thaiv kev tiv thaiv los tiv thaiv cov vuam los ntawm kev sib kis ntawm atmospheric. Yog tias cov roj tiv thaiv tsis tau siv tau zoo lossis yog tias muaj cov xau hauv qhov chaw vuam, nws tuaj yeem ua rau muaj xim tsis zoo ntawm qhov chaw vuam.
- Vuam Parameters:Cov kev txwv tshwj xeeb uas siv thaum lub sijhawm vuam, xws li qhov hluav taws xob, tam sim no, thiab lub sijhawm vuam, tuaj yeem cuam tshuam cov xim hloov ntawm qhov chaw vuam. Kev siv cov kev teeb tsa tsis raug yuav ua rau lub ntsej muag daj.
- Hom Hlau:Cov hlau sib txawv tuaj yeem cuam tshuam qhov sib txawv ntawm cov txheej txheem vuam. Qee cov hlau muaj ntau dua rau kev hloov xim dua li lwm tus. Hom khoom siv welded tuaj yeem cuam tshuam cov xim hloov.
Txhawm rau tiv thaiv lossis txo qhov yellowing ntawm weld me ntsis hauv cov txiv ntoo qhov chaw vuam, cov kauj ruam hauv qab no tuaj yeem ua:
- Kev tu kom zoo:Xyuas kom meej tias cov hlau qhov chaw yuav tsum tau welded yog huv si thiab tsis muaj tej yam kab mob. Ua tib zoo ntxuav thiab degrease cov hlau kom txo tau qhov kev pheej hmoo ntawm discoloration.
- Optimized Vuam Parameters:Kho qhov vuam tsis zoo rau qhov kev pom zoo rau cov khoom siv tshwj xeeb thiab tuab yog welded. Qhov no tuaj yeem pab ua kom tiav qhov huv, tsis muaj xim tsis zoo.
- Tiv thaiv Gas Control:Saib xyuas cov roj tiv thaiv kom paub tseeb tias nws muaj txiaj ntsig zoo tiv thaiv cov vuam los ntawm cov pa phem. Gas ntws thiab kev pab them nqi yog qhov tseem ceeb.
- Kev xaiv khoom siv:Yog tias ua tau, xaiv cov khoom uas tsis tshua muaj xim tsis zoo thaum vuam, lossis tshawb nrhiav lwm txoj hauv kev vuam rau cov ntawv thov tshwj xeeb.
Hauv kev xaus, qhov yellowing ntawm weld me ntsis nyob rau hauv cov txiv ntseej qhov chaw vuam yog ib qho tshwm sim, thiab nws tuaj yeem raug ntaus nqi rau ntau yam xws li kev kub hnyiab, cov khoom sib kis, tsis txaus shielding, vuam tsis, thiab hom hlau siv. Los ntawm kev ceev faj kom tsim nyog thiab ua raws li cov kev coj ua zoo tshaj plaws, nws tuaj yeem txo lossis tshem tawm qhov kev hloov pauv no, ua rau kom huv thiab zoo nkauj dua weld.
