Kev nyab xeeb thiab kev noj qab haus huv hauv kev ua haujlwm vuam

Vuam, raws li cov txheej txheem sib koom ua hlau, muaj ntau yam kev siv hauv kev tsim khoom, kev saib xyuas lub tsev thiab lwm yam haujlwm.Txawm li cas los xij, kev ua haujlwm vuam tsis yog tsuas yog cuam tshuam cov khoom siv tes ua haujlwm nyuaj, tab sis kuj muaj cov teeb meem kev nyab xeeb thiab kev noj qab haus huv.Yog li ntawd, peb yuav tsum tau ua tib zoo saib xyuas thiab ua raws li kev tiv thaiv tsim nyog thaum ua haujlwm vuam.

Ua ntej ntawm tag nrho cov, lub teeb arc, sparks thiab kub siab generated thaum lub sij hawm vuam txheej txheem yuav ua rau puas rau lub qhov muag thiab daim tawv nqaij.Yog li ntawd, cov welders yuav tsum hnav tsom iav tshwj xeeb thiab cov khaub ncaws tiv thaiv kom ntseeg tau tias lawv muaj kev nyab xeeb.Tsis tas li ntawd, cov pa phem thiab cov pa taws uas tsim los ntawm kev sib txuas kuj tseem tuaj yeem ua rau muaj kev puas tsuaj rau lub ntsws.Thaum lub sijhawm ua haujlwm, qhov chaw ua haujlwm yuav tsum tau khaws cia kom zoo qhov cua thiab lub qhov ncauj qhov ntswg yuav tsum tau hnav kom txo tau qhov nqus ntawm cov khoom tsis zoo.

Qhov thib ob, kev ua haujlwm vuam kuj tseem tuaj yeem ua rau muaj kev nyab xeeb xws li hluav taws kub thiab tawg.Yog li ntawd, ua ntej welding, nws yog ib qho tsim nyog yuav tsum xyuas kom meej tias qhov chaw ua haujlwm tsis muaj cov khoom tawg yooj yim thiab cov khoom tawg thiab ua kom muaj kev nyab xeeb ntawm cov khoom siv nyob ib puag ncig.Nyob rau tib lub sijhawm, kev xaiv thiab kev ua haujlwm ntawm cov khoom siv vuam yuav tsum ua raws li cov lus qhia tshwj xeeb kom tsis txhob muaj kev nyab xeeb ntawm cov khoom siv tsis ua haujlwm lossis kev ua haujlwm tsis raug.

Tsis tas li ntawd, kev siv vuam ntev ntev kuj tseem tuaj yeem cuam tshuam rau lub welder lub cev, xws li kev tsis pom kev thiab kev laus ntawm daim tawv nqaij.Yog li ntawd, welders yuav tsum tau kuaj xyuas lub cev tsis tu ncua thiab ua tib zoo saib xyuas kev ua haujlwm ntawm lub cev thiab cov sijhawm ua haujlwm kom txo tau lub nra ntawm lub cev.

Txhawm rau kom ua tiav, cov teeb meem kev nyab xeeb thiab kev noj qab haus huv hauv kev ua haujlwm vuam yuav tsum tsis txhob tsis quav ntsej.Peb yuav tsum ua raws li cov txheej txheem kev nyab xeeb, ntxiv dag zog rau kev tiv thaiv tus kheej, thiab ua kom muaj kev nyab xeeb thiab kev nyiam huv ntawm qhov chaw ua haujlwm.Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem tiv thaiv kev nyab xeeb thiab teeb meem kev noj qab haus huv hauv kev ua haujlwm vuam thiab tiv thaiv lub neej kev nyab xeeb thiab kev noj qab haus huv ntawm cov welding.
